  1. I have a question regarding 5.3L chevy truck engines for a 280z 2+2 swap. The plan is to use a v8 swap kit like the Hoke performance or Johns cars, headers (CX racing has some good ones), fuel injection, LS1 intake manifold, and a manual throttle body. My question is does anyone know which chevy 5.3L truck engines will work? I know the early Vortech engines are popular, like the LM7 and L33, but will the more modern engines 2007-present work as well? For example, will the Gen IV LY5 and LMG and Gen V L83 engines still work? Has anyone gone this route, or are these engines too difficult to wire and work with? Also, will these engines mount up to a T56 or TKO600 manual transmission? Thanks very much for the help! The only info I found by searching the forums is that these engines have DOD which I would need to deal with.
  2. Greetings from Montana. This is my first post so let me know if it's helpful. So my '75 Z has been sitting in a garage since 2013 on account of the clutch pedal lost its pressure and the fuel system was all gunked up with rust. I went off to school so I had no time to work on it. I came home this summer and have been working on it for a month or so now when I can afford it and have the time and finally this weekend it should drive once again! I came to the conclusion that the priority would be the gas tank and fuel system. So I dove right into draining the gas and stripping the tank from the car. What I had found next was a nightmare. Layers upon layers of rust in the gas tank! First thing I did was sloshed around quite a few nuts and bolts with some old gas and banged on it very carefully with a hammer to break some of those rust chips up. I drained what I could of the broken rust pieces and began my search for a cheap alternative for a rust removing chemical. Come to find out, white vinegar works wonders if you submerge and soak rusted metal for a couple days. I got 17 gallons of the stuff for 2$ a gallon at costco because you will want to fill the entire tank to prevent flash rusting on exposed metal. I filled the tank and sealed it all off with duct tape except for the small tube at the very top of the tank so it could breathe the fumes. I let it soak for 3 days like this and I would suggest placing whatever you are going to drain the vinegar into underneath the drain plug BEFORE you fill it because you won't be able to lift it yourself after it is full of 17 gallons, unless you are Hulk Hogan. Once you are satisfied with the amount of time it has soaked(anywhere from 24 hours for minor rust to 3-4 days for caked on rust), unscrew the drain plug and commence draining. After all but about a gallon or so has drained, grab hold of the tank and start rocking it back and forth and 360 degrees, slowly to get all the flakes to drain. You could bang on it with a rubber mallet or hammer again as well. Once it's all drained, take your phone camera and put it on video with the flash on and poke it inside the sending unit hole. You will be amazed looking around at how well the vinegar works. You will see mostly bare metal. Unplug all the holes and allow it to dry for a day or so. I taped an air compressor blower to one of the holes to give it a blow dry for about an hour right after I drained the vinegar. There will be flash rusting and there is nothing you can do to avoid that unless you wipe it clean with a rag right after it has drained, which is impossible with a gas tank. But don't worry the next step will cover that. Now go to your local car parts store and ask for a liquid gas tank liner, any brand will do. Make sure you read the directions and get enough, especially if you want to do 2 coats. They usually come in 1 quart cans that will usually only cover about 12 gallons. The brand I got was this way. For my '75 280z the gas tank is 17.2 gallons so I had to get 2 quarts. Once you are satisfied that your tank has dried completely, it is time to put your first coat on. Look inside your tank and you will see that it has a divider to the skinny part of the tank. For this reason, I plug all the holes except for the sending unit hole on the tall part of the tank and the gas outlet hole on the narrow part of the tank. This allows you to fill both halves without worry of missing a spot with the coat. You need a good funnel for this stuff. Fill the narrow half with one quart first because it takes longer. Then fill the sending unit half with the remaining quart. Plug the remaining holes. Very slowly roll the gas tank around in your arms 360 degrees on all planes for about 15 minutes or until you think every spot has been touched by the good stuff. It's kinda like the consistency of molasses and it dries like a rubber glove so be thorough. After rocking it around on all planes I would let it sit on it's bottom for 5 minutes then on it's side for 5 minutes then on it's top for 5 minutes then on the other side for 5 minutes and back again on the bottom. I did this for an hour or so while I was changing the oil. I wanted to make sure that bare metal would not show. Once you are satisfied, place it on top of some saw horses or an old cooler or something and place one of the liner cans under the drain plug and unscrew it. Remove all plugs so it can dry evenly. On all the small openings, I took my air blower and blew a small amount of air through to make sure the liner didn't plug them. I would highly recommend this. Let it dry for a day. Come back and check to see if it dried evenly. If there are bare spots, do a second coat, if you have enough left over liner. I did anyway. Let it dry for a day and a half just to be safe. This next step isn't necessary but I recommend doing it since you already have the hunk of junk out. Get a can of rust proof spray enamel from your hardware or car parts store. You could get any color you want. I just got black cause I don't know what the paint job will be on the car yet. Tape all the holes, Air blow it free of debris and sand the rusty spots, air blow again, then commence spraying the enamel. Let it dry. Now that the gas tank is complete, check all your filters. My Z had a small filter between the outlet and the fuel pump. When I took it out, it was pack full of rust to the brim. I have looked all over the market and can not find a part to replace this filter. I tapped all of it out and submerged it in vinegar as well. There is a strainer between the fuel pump and the fuel line to the block. I removed that and soaked it in vinegar. I installed a new fuel pump while I had the gas tank out. And there is another larger fuel filter by the engine block under the hood. I just got a new one of those for 20$ and installed it. Once your tank is completely dry, put it all back together. I suppose you could seafoam the system and bleed it if you want to go a step farther. I probably won't since I know the gas tank is good and that is the source of bad gas. I figure any bad stuff that remains will get washed out and burned off in a day of driving. Thanks for reading my first post! Hope it helped!
  3. Thought I would actually post my build in the project section since this is a project. As the story goes my 1995 240sx was stolen on 10/21/12. Had SR20DET S15 with the S15 6speed, Nistune ECU management. Tomei 272/272 cams. 750cc injectors, Z32 MAF. AEM tru-boost controller. Ran the J30 dif with abs sensor that I used with a Digital decoder to convert signal for the speedo. Full gauge setup last tune done on the car in July put 305 HP to the rear wheels at 15lbs of boost. Car had working A/C. Fortune 500 coilovers, Isis rear adjustable suspension. Paint and body work done in July as well, Navan front bumper, side skirts and rear valiance. Here is a dyno pull!! http://s158.photobucket.com/user/melbellwood1/media/1995%20Nissan%20240sx/20110923_162204.mp4.html Here is a run at the track!! http://s158.photobucket.com/user/melbellwood1/media/1995%20Nissan%20240sx/20120113_185224.mp4.html The gray 240 is a friend of mines, He runs deep into the 11's at the track makes 390hp runs sticky drag radials all with A/C! Car was recovered 3 days later stripped. Did not have full coverage, my stupidity. Makes ya sick. Now onto the next project. Found thru the internet in Salt Lake City Utah. Car originally bought by person when living in California. Car was originally green and repainted in the early 80’s red. Late model 1974 260Z. Car had updated DGV carbs installed. Western Star wheels and headlight covers with a rear deck louver. Car ran great for short trips to work and out. But my first road trip to a car show about 60 miles away the car overheated on the freeway cruising at 70mph. So switched out for a new radiator and thermostat. First upgrades was a twin pipe exhaust through twin glass packs. Sound is awesome. Power is limited. I was originally going do a head swap, raise the compression and run triple 2 barrels. I wanted to get 200+ hp. After driving the car for 3 months and missing the pull of a turbo, I decided to do a turbo. Didn’t help that a close friend drives a Golf daily with 400+ hp to the front wheels and owns a tuning shop. I decided from research (not deep enough to add a turbo to the 260Z motor because I am over 4 times that cost so far and still counting). Looking it over I thought with intercooler and buying all the parts that I could do this with only about $1500 out of pocket and I would have a turbo driver! HAHAHAHA..... Plans are to be a driver with some track use. Here are some of my trips to time attacks and road course racing. http://s158.photobucket.com/user/melbellwood1/media/Tooquick260z/20130216_150116_zps0eee095d.mp4.html At the point of putting the parts together and driving my car some issues started happening to the 40 year old car. The transmission that worked flawlessly started being difficult to put in first gear (after removal realized it was the slave cylinder no pressure). It developed an exhaust leak, thought it was the new exhaust that I installed. During removal of the intake realized that the #6 cylinder exhaust bolts were gone, yeah missing. Also the head gasket was leaking. I found great deals on all the parts and put them together. Turbo, ECU, AFM, wiring harness etc. Look at the boxes of parts WOW! I located a P90 head and had it rebuilt and flycut. Bought some cam tower shims from Derek, member on hear from Ocala. I put new valves from the 75-78 head with some addition spring spacers got them lined up. Before.... After.... Bolted to the head with cam timing done. Cleaned the engine compartment and painted with a few coats of clear. Looks like a deep dark hole where all the money has gone. Who’s counting right! While this was going on my brother toasted his 1993 300zx by letting the timing belt break, can you say interference. With the tranny going bad(auto) and a/c problems and other issues he decided to part it out. So, I purchased a lot of the parts from him. Breaks, Diff, MAF, Master cylinder and booster, and drive shaft to put in my Z. To put all that stuff on I purchased the rear setup from TechnoToyTuning. Nice stuff. Rear Z32 diff mounts, coilovers with Tokico’s. Old and new clutch, I should hook now!!! Handle the projected 250 HP! So since I had a 6 speed in the stolen car I decided to go with the same tranny. S15 6speed. I researched and found a few people with attempted installs of this tranny but no one had a step by step build. I posted I wanted to do this and a fellow member Xnke (Jacob) said he could help. He said to send the 6 speed with an S30 bellhousing. So I purchases a 6 Speed from JDM Tech of Orlando put them on a crate and sent to Xnke. He then cut the S30 bellhousing and mated it to the S15 6 Speed. Jacob informed me that this is actually a Mazda MX-5 6 speed. he can source and work on these tranny's! Awesome. Here are pics of taking the S30 tranny out and apart. Then with the 6 speed back ready to be installed. Znke even machined the speed access hole for the S30 speedo cable. He got the 4.11 speedo gear that will work great with the Z32 4.09 rear diff. Tranny installed and mounted in Stock tranny mount! Street T installed to run the turbo oiling line. Electric fans installed,,,, Isis 12" fans Stay tuned for the process.......
  4. Hi everyone, I've been having some issues with my door that I'm trying to fix but frankly I need some help with what I can actually do to fix it. I made a video showing and telling the issues I have: My hope was some folks on here could watch it and give me some guidance as to what exactly is wrong and how to fix it. Thanks, - Pac Man
  5. Hi All, Well I am finally getting close to building another Z. Now that the prices have risen 10 fold or so, I figure I'll spend my money... LOL. This would be my 4th Z car. So, I am looking into doing a complete build on an S30, probably a 76-78, as I just cant justifying tearing up a 240 now that the values are through the roof. I am looking at a complete build, engine, tranny, suspension, brakes, etc, etc. I am thinking about a few different motor configurations. Ideally I would like to see RWHP in the 375 to 425 area, and torque somewhat commensurate with those numbers. I have thought about a NA motor, but not so sure I will see those numbers from an NA motor. As I hate turbo lag, but love the top end of a turbo, I was pondering a twin scroll type of a set up. My budget is in the $15K to $20k area for the motor. As many of you on this site have much more experience in this area than I do I would love to get some input from you as to what your thoughts are on this project and which way would you go, NA 3.2 motor, slightly built RB series motor, single twin scroll or twin turbo? Also, if I decide to go RB who is a good RB engine builder out there, I am in the Washington state area. I should add that I am not looking for a drag car, but something more like a solid GT car that can also handle some light track day fun. Thank you in advance for your input.
  6. Hello fellow HybridZers, I'm looking for a whale tail for the S30s, hopefully in better condition than not. Willing to pay shipping from anywhere in the US, I am located in 92691. My phone is the best way to reach me, text or call. 949-939-7573. Thank you for your help in advance!
  7. Hi my name is Harry and i am in the prosses of buying my first classic car, a 1975 280z. I have kept my head down and been reading a fair amount on diffrent forums about common problems with these cars. I plan on daily driving the 280z as stock untill i have the money to do what i want with it properly. So i was just wondering what are the things that i need to do first to try and keep the old girl as reliable as she can be. Ive read that there is some issues with fule tanks rusting and fule lines getting cloged. Im going to try and have a look in the tank with it still in the car as i dont have a garage at the moment so will find it hard to store parts like fule tanks ect. Obviously if the tank is full of rust then i will just have to remove it and get it sorted. Ive also read that there is a heat soke isue with the fule in the fule rail boiling after shut down of the engine after a few minutes. I dont much fancy getting a fan to cool this down so was wondering if heat rapping the exhaust would help this or i sould jsut get a nice new fule rail. The car i am buying has a very nice chasis with very little / no rust so this shouldnt be a big issue in the short turm. I am planning on a full body sand blast back to bear metal, repare and dammage/rust and respray in the future as well. All of the hoses are proabley ging to be my first job to change as i cant see 40 year old rubber not springing a leak at the worst posible time. I also plan on changing all of the bushing for the suspension soon aswell. My plan is for polly as i dont mind a harsher ride unless there is a reson not to do this. I also want to chage the springs and struts to slightly lower the car, only an inch or so as i think it looks nicer. Is there anything that i have missed or things that i need to do first? Any and all insite would be much appreciated. Apologys if i have spelt anything wrong, there defiantly will be, i just cant spell Second apology is for no pictures at the moment, my phone with the pictures broke and i have lost them. I should, fingers crossed, be getting the car in a month or so now and am getting rather excited. I live in the uk so any pointers to shops to buy parts from here would also be much appreciated as most are based in the us. Come on free trade deal with the us Edit. Almost forgot to say the obviouse, all fluid changes, filters and spark plugs. Do you think i should get new points and spark leads?

  9. Looking for a clutch pedal for an s30. I think they are all the same. Thank you!
  10. As you all can undoubtedly tell I'm new to the forum and decided that I might as well document my build for my own purpose of keeping track of things and organizing my plans and thoughts. This is the first time I've created a build thread for any of my projects so bare with me and don't pile the BS up to high, I'm kinda short and I don't swim to well in the green stinky stuff. I've always loved the look of Zs and I have wanted one for quite sometime. The opportunity has presented itself recently for me to get one from a co-worker who has decided to part with an extra "parts" car that he has a few miles from my house. I checked the VIN tag and it appears to be a '75 280z. The engine and manual trans are in unknown condition and the body is in desperate need of paint and some rust repair, but what neglected S30 doesn't need all of those areas fixed. All of that a side the cost of the car is pulling the LH door for him to install on his '70 240z or find an acceptable replacement for his current door and the car is mine. A couple of days after being told that I can have the car a local classifieds had a fairly complete VK56DE out of a 2005 Armada for free with a spun #4 rod bearing and otherwise pristine internals. The seller included a fairly complete engine wiring harness, injectors, fuel rails, intake, block, heads, internals and oil pan as well (some items are already removed and on the shelf). I've always liked the raspy growl of ITB injections setups but can't stomach the price tag on my salary, but while looking around at a few other VK56 builds on other forums I decided that if I'm going to go thru the all of the fabrication headaches of stuffing the beast in I might as well go big or go home. So I researched some different options using extrudabody, gsxr throttle bodies and a few other motorcycles until I came across some really inexpensive BMW units on ebay. I paid $2 and shipping for 4 throttle bodies in a bulk buy and they arrived last friday, and another one is on it's way with the injector and TPS for under $20. I'm on the look out for some good deals on the remaining three units. These ones have a stock 336cc/min injector vs the vk56 286cc/min from what I've been able to find online, they also have a straight thru 45mm ID and the injector will clip right into the factory VK fuel rail. I haven't decided if I'm going to use the BMW injectors for sure yet, I'm thinking initially I will just install the VK units with a small press fit bushing to reduce the bottom sealing boss to 14mm from 16mm. I already ordered some replacement shaft bushing as they are a known problem for the BMW oilheads and talked to a few friends about linkage and shaft design. I think I can get an 8mm precision stainless shaft to run thru all 4 on each side and then put a cam arm on each bank with a solid link to a torque arm and cable pulley in the center done failry easily. Once I finish getting the adapter plates for the head to throttle body modeled in solid works I'll be able to get a better idea of the specifics. The spun rod and crank need to be addressed first though, but I've got some mad scientist ideas for that in the back of my head too, we'll see what the engine shop machinist has to say first... As far as drivetrain goes I'm still researching and trying to decide what transmission option will be the best in regards to price, ease of conversion, longevity and power handling capabilities. The top two choices currently are a Z32 manual or a CD0009. Differential will initially stay the stock open R200 until I get the bugs of the engine and trans swap all worked out and then as funds and the necessity for stronger parts come into play either an R230 swap of some form or the Ultimat IRS 8.8 that wfritts911 has worked out in the drivetrain section. Just clarify for those still reading this I am well aware of how difficult and intense this swap will be and that many people all over the web have started, talked about and never completed the swap but there are some who have paved the way in S130s, buggies, 240sx, 350s and 370s. All of that being said this will be a pretty drawn out and long process as I don't have a set pool of money to just throw at a project until completed. I've got 4 kids and I'm the bread winner for our family working 1 full-time and 2 part time jobs. I do how ever have some very good connections with a few local machine shops, mechanical engineers, fabricators and professional welders. I also work full time at a government shop where I can use any of the tooling and facilities after hours that I don't have at home as long as I clean up after myself. That's about all I can stand to write for now, as things progress I'll try to take lots of pictures and document as much as possible.
  11. Hey guys, Sorry about posting this in the FAQs first, didn't see what category I was in. I recently got the Zcardepot.com Rear disc brake conversion kit, the sport one with the drilled and slotted discs. It uses a maxima caliper. They didn't send me any install information, just a box of parts. I have searched around and haven't found anyone who has documented the install. I did my best to install it how it makes sense, but I want to make sure that it is correct before I bleed the system and drive the car. I've posted some pictures below of my install, sorry for the lighting. I usually do all my work with a headlamp on, so pictures are either too bright or too dark..... I posted a picture of the brake line included, as well as letters showing where they are located on the installed caliper. I used the factory bracket to hold the middle of the brake line fitting. I also used the caliper with the R for right side on the right side of the car. I literally couldn't even find info on how the pads are supposed to be installed. They seem to be left/right specific, as the pad touching the caliper piston has a large tab off the back of it that sticks out. Mostly I am wondering: 1. Is the caliper even in the right position? 2. Is the brake line routed correctly? 3. I read that to make the hand brake cables work, i should swap them across the car so they are short enough to use them on the front of the disc. That is my plan, but have yet to do it. Is it correct? 4.Is there anything I am missing documentation-wise? I can't even find a maxima caliper swap guide. The one I found has broken picture links, so it isn't much use. Thanks in advance!
  12. He Guys, right now i am doing a full restoration of a 280z from 1978. The car little rust, but it got welded together from 2 different cars and was sold to me as „original“.... So i am looking for a 280z shell in good condition, preferedbly from california or desert area but not a must (no accidents, minimal/ no rust). If anyone has one in the garage or knows someone who wants to get rid of his project, i would be more the happy to hear from you. Thanks a lot
  13. I currently have a 240z with a chevy small block installed but am planning on upgrading to an ls3. The car has upgraded suspension but when going on the freeway the car drifts side to side with no steering input and I think this may be do to the weak chassis. Would it be worth it To sell the car and upgrade to a 280z which I have heard has a stiffer chassis and do the engine swap into that car instead of the 240z?
  14. I finished my LS1 and 4l60e swap this spring into my s30. Have enjoyed driving it this year. My plan this winter was to pull the motor and trans and rebuild them. Both are bone stock. Motor is going to be completely rebuilt with c/h/i. While trans is getting built up to handle more power and fix failing clutches. That was until my friend at the junkyard called and said he has a ls3/6l80e with harness and pedal out of a 2013 Camaro ss with 50k miles. I can get it for about $4300. I know the ls3 is no issue, but I can’t find anyone who has put a 6l80e. How much bigger is it than a 4l80e? My LS1 has about 180k miles on it and by the time I rebuild both it and trans with a higher stall, I figure I will have about what the ls3 pull would cost me. My Z was originally an automatic, as was the donor z28 Camaro I took the original drivetrain from. I guess I could always convert to manual and run a t56. Is a 6l80e something I can message in, or is it a major surgery not worth messing with.
  15. Sakura Garage is pleased to announce the availability of the Stance USA fully adjustable coilover set for the 240Z, 260Z, 280Z. See our website: http://sakuragarage.com/products/datsun-suspension for order information. - We use Stance USA Super Sport inverted struts. (No hood clearance issues) - Your choice of spring rates. - Swift Springs are also available as an option - Weld-on adapters included - with proper size and length for 240Z or 280Z strut configuration. Our kit allows a wide ride-height adjustment range** - from stock ride height to - well - dirt-nasty-low... We've also developed a bolt-on Camber Plate* for use with the Stance USA coilovers. Our camber plates allow the maximum possible adjustment range in an S30 strut tower! Included templates for drilling and cutting strut towers Drilling template uses stock top hat holes for proper alignment every time Cutting template assures you remove only what's needed to install camber plate Our stainless steel top plate (vanity plate) gives every installation a professional look Please note - this coilover kit requires: - cutting your stock strut tubes - welding the threaded adapters to your stock suspension - the bolt-on camber plates require cutting some material from your strut tower $1595 + shipping with camber plates $1295 + shipping without camber plates (modification must be done to stock top hat) * The camber plate is bolt-on but still requires some cutting of the strut towers to allow for installation of the camber plate and movement of the pillow ball for camber adjustment. ** Our primary focus is to give you a high-quality upgrade with full adjustability to give you maximum suspension performance for your dollar. But if your primary focus is low - you got it...
  16. Did some digging around, and I'm going to get an adapter set made to adapt the 240z spindles to s550 disc brake mounting points. This are massive brakes that sell for pennies on the dollar. Good for the guys with 800 hp ls v8s and 2jz setups. Going to use 65 mustang hubs which have the same A2 and A6 inner and outer bearings as the 240z spindles. Still got some fitting to do, more to come later. We are talking 4 piston 14 inch brakes for under $200 sometimes. Or 15 inch monster 6 piston brembos setup if your heart desires. Anyways, let me know if anyone would be interested, I'll be building the setup for my own 240z, but if 5 or 6 people want some, I will make extras. I did something similar for 1968 dodge chargers and people love them. Made an adapter that allowed use of 2014 mustang brakes on drum hubs and people have been buying and using them with great results, so I'm not new to designing something that works and offering it to people. I'll post pictures as I make progress. Currently dealing with a child who has a fatal heart defect so this may take a few months, but this is something I'm seriously designing right now to go along with the super 8.8 rear irs conversion I'm developing... The idea is to have a balanced braking system off a 2015 mustang complete, front and rear, no mismatch.
  17. I searched around and didn't see any mention of it yet (on hybridz), Although I am not a fan of Richard Rawlings and his show since Aaron left, I really like this car ever since I saw it on social media. I was like awwww when I saw the A$$ monkey plate. Still, the exact direction I was going with my 2+2, and now I feel like i have to switch things up to be accused of copying this celebrity Z. Little run-of-the-mill, but very sharp and tasteful. And its good to see the 2+2 body style getting some more attention!

  18. Hello everyone! Im new to the Hybrid Z forums so I thought I would start a build thread for my build on my 1975 280z. Current car: 1975 Datsun 280z Mods: Subaru Power Steering conversion, Full Eibach suspension, aftermarket swaybar + full polyurethane bushing conversion, Toyota front disc conversion, aftermarket A/C installed, 240z driveline, (im probably missing some things so I'll update it as I go.) I have roughly 20 years of receipts of all the work done to the car. I just recently acquired the car so everything listed above was done by the previous owner. Now here is my plans for the rest of the car: [Key --> Green = Acquired Crossed Out = No longer using ] Turbo Spec Motor 7.31:1 Compression (N42 block/P90 Head) Either T3 Precision Turbo or T3 Turbonetics Arp Head Studs External Wastegate + Blowoff Valve + AFR + Boost Gauge Oil Cooler Turbo dizzy 82/83 280zx + shaft Megasquirt EFI kit from Softopz 550cc RX7 Injectors / 440 cc Supra Injectors (For Sale, Message me if interested I will ship at no extra cost) Turbo Oil pump (thoughts?) 240sx throttle body + Sensor Intercooler + Piping Oil Pressure T for oil lines to turbo (in & dump) 2mm head gasket to lower compression to 7.8/1 wastegate Downpipe (need a dump tube as well for the wastegate) Turbo Manifold(x2 anybody want to purchase my extra?) + wastegate adapter 2.5" exhuast / black widow widowmaker Upgraded Ignition System (not sure which to go with yet, suggestions??) NGK Plugs Pallnet Fuel Rail Kit + Throttle Body Spacer Electric fuel pump upgrade + New Pressure Regulator ------------------------------------------------- UPDATES: Update 11/3/2017 - With some great info/advice from the comments, I am highly considering going with a megasquirt plug in play kit made by softopz (just waiting on his reply at the moment). I've also decided I definitely DO want a bigger cam, so any suggestions on that front are helpful as well. Also I have added that if I go the megasquirt route I am ordering a pallnet fuel rail to compliment it. Update 11/4/2017 - Alright after meticulous research, hours of comparing prices and talking back and forth to people who have done the cam/turbo builds and the potential power gain (and I do mean COUNTLESS hours of this haha), I have decided to completely ditch the whole cam and head upgrade idea and go the turbo build route. For almost the same price (actually a bit cheaper) I can get alot more smiles per gallon with the turbo build. There just isn't enough power to be had on the N/A build for the amount being spent. So as of right now this is the game plan. I will continue to add to this as I see fit, everything will be updated on this original thread post. Part 2 11/4/2017 Just went through the receipts on the car (dating back to the late 90's) and boy was I in for surprise! All of the tedious work to maintain the stock L28 has been completely gone through by the PO! For example the timing chain kit from Z Motorsport has been installed, Tune up kits routinely done, fuel pump and filters / lines replaced, harmonic balancer replaced, and the list goes on. I couldnt be more happy with this purchase!! Did I mention the PO gave me a close ratio 5-speed for the car?! This car amazes me and I am very thankful that it has had such meticulous care over the years. Update 11/7/17 Added some parts to the list. Also purchased a turbo manifold on facebook for 150 bucks! ***Update 11/10/17**** I have purchased a complete L28 turbo motor setup at a very very good price! Here are the engine specs: L28 N42 Block with dished pistons, P90 Head, N47 intake, turbo manifold, Pallnet fuel rail + Fuel pressure gauge, 440cc supra injectors, rebuilt chinese housing turbo with turbonetics internals, turbo dizzy, and assembled with ARP studs. Came with some other misc parts as well. Update 11/13/17 Link to spreadsheet for parts list: https://docs.google.com/spreadsheets/d/1iOiWBJyjQH3KEkLnBor0snwgOvXaUo4I0qIo1ZDYFZo/edit?usp=sharing Update 12/7/17 Tore down the entire motor and I am going to rebuild the bottom end and the head and all freeze plugs timing chain etc... Ordered all the parts just need to hot tank the block to start assembly again.
  19. hello everyone! im new here but ive had my 280 for 2 years now. the engine turns over but it will never fire up. ive switched out plenty of relays and electrical components, cleaned out the fuel lines and installed new fuel pump. ive just decided to scrap the EFI system and switch to carburators. i was wondering if this would be the right place to ask the right person for some good but affordable carbs that will fit onto my 280z (cali model) thanks
  20. Hi I'm currently researching swapping a KA24DE along with the KA 5 speed trans into my 280z and have questions regarding mounting. I plan on running this setup due to a turbo build planned. I've read the trans is able to be mounted via the stock mounts but I've also seen that its not possible and would like an answer to the debate. Im also planning on using McKinney motor mounts and was curious if anybody has any experience with them and what they think of them? Also, I've heard I may need a custom driveshaft and was wondering if that was true or not. I've read on a forum previous that I won't need to but I'd like to know if I need a custom one before I do the swap.
  21. I pulled my engine and tranny last weekend while my kids and wife were out of town and now I want to restore my engine bay. I would like to know from those who have performed this swap what I can throw away. I would look at the photos of other peoples' engine bays who have performed the swap, but I'm not sure what has been hidden as opposed to demo'd/removed. Please assume: I will be keeping the AC system, relocating the battery to the back. Thanks to everyone, I have been using this, my FSM, and youtube to help make a lot of this happen. In case you're wondering, my car came painted like this. I'll be dreaming up a new scheme either to match or something else. Jeff Engine Removed
  22. Hey all, bought a pair of wheels with some positive offset, so I got a set of 25mm wheel spacers all around to make them fit. I went with the pair listed at zcardepot: https://zcardepot.com/wheel-spacer-set-pair-1.html I was hoping this would "ensure" that they fit all around (since zcardepot specializes in z-cars) but alas, the fronts do not. On the front (stock) hub, it seems that rubber-ish (might just be gunk lol) piece sticking out doesn't clear the center bore of the spacer. I need about 1/8" more clearance. See the following pics. Should I have expected this? Is there just gunk build-up on my car that needs to be cleaned off? What is this rubber extension anyway? Am I screwed unless I get new hubs? FYI - the wheels themselves have 73.1mm inner bore (~2 7/8") and would likely fit on the hub if they were correct offset. I have to use a hub ring to properly center them on the spacer outer edge. Gap when fitted: The center bore appears to be machined out to compensate, but it is just a bit too narrow: OEM wheel has 2 7/8" inner bore: Spacer has 2 5/8" inner bore:
  23. I've got a 1975 280z with a stock suspension. This is the only Z I've ever driven so I can't really compare it to anything but I feel like the ride is pretty rough. I can feel every tiny imperfection in the road and if I hit any kind of hole or bump at a good speed it feels pretty bad. It gets very floaty on the freeway. I've got it on 215/55r16 tires. I don't race it or anything so it's just for normal street driving. I looked around at a bunch of other forums and from what I read it looks like Eibach Pro Spring Kits rated at 150lb in the front and 175lb in the rear is what people are suggesting, with Tokico HP struts. I was wondering if anyone is running this setup and could maybe say anything about it like if it isn't too rough for just everyday driving. Or if maybe something new has come out that I didn't find and anyone had suggestions.
  24. So about a week ago my car started to have issues when it got up to temp. It would originally start, idle, and run fine, but after the car began to get warm it would lean out like crazy (have a wideband installed) and there would be no response when throttle was applied under load. It did this for a few days until it decided to completely die on my way home from the gym. After a few minutes the car would start and idle lean on the side of the road, but then die immediately with any throttle (not under load). The engine is from a 1983 280zx turbo. After a little bit of research I'm wondering if it is my Crank Angle Sensor in my distributor, but I'm still very confused. I don't think it's a wet Throttle Position Sensor because I had that problem recently and I removed it/dried it out and the car ran fine. Also the symptoms are different due to not even idling rather than failing at 2000rpm. Short video with symptoms: https://streamable.com/nn9ls
  25. Hey all, Recently looking at getting into older Z's. Was gonna do an L28ET swap as my first foray into engine swapping (given its apparent simplicity) but if I can avoid it I would rather do that and focus on the more "fun" parts for me (suspension, bodywork). I found a 1978 280z 5 speed with '82 zx turbo motor and oil cooler for sale locally. Guy has owned it since 2004, did the swap himself, and driven for ~3k miles a year. It is right at 100k miles and garaged when not in use. Looks like pretty much stock everything else (suspension, driveline, body, interior, etc.) Body is mostly straight but has a few quarter-sized holes as well as 2-3 rust spots spots. He is asking $9,995, what do you guys think is fair?
