Hey everyone, this build will document my tear down and rebuild of a 1977 280z. This is my first restoration project and as such, I plan to take this slowly and methodically so I can remember how to build it back up! My goals for this build: Complete teardown, soda/abrasive blast entire body Fix any rust and dents Paint - Not sure what color yet, but factory color is blue. I like the blue color and might think about a white racing stripe, but again, I am not 100% on the color scheme yet. Install a 5.3 LS (LM7) engine and t56 6-speed (eventual power goal is 350-400 hp) Install a R200 LSD (final gear ratio TBD). The car has a R180 open diff most likely, I will confirm as I get to removing the suspension. Refinish the interior - Most the plastic is in terrible condition, everything is very brittle and the center console and dash are cracked pretty badly. My goal is a light tan leather interior with some modern updates (power windows, locks, seat heaters, new head unit, racing wheel). The interior is white/tan currently and I like the white with blue combo so that is in the running. I feel I am about 1-2 years, at least, away from having to decide on this. Complete everything myself so I can learn about each and every aspect of this process. I might consider farming out engine rebuild because I really don't want to mess that up, but my initial plan would be just to use stock internals on the engine, and rebuild the engine after the car is up and running for a while. Have Fun! Don't get too frustrated or more importantly take a break when stuck. My next post is going to detail the current state of the car. I welcome all input, advice, and suggestions!

I recently fixed an engine oil leak that made a mess all around the underside of my 77 280z. After a few months of the leak stopping I noticed that my transmission is also leaking at the rear where it meets the the driveshaft. I also noticed it only leaks when I drive it. Is this because the transmission might be overfilled? Or could it be a bad seal? If I have to remove the driveshaft, what's the best way to do it? I'll add some pics, you can see the oil drip and splatter all over the car. Thanks!

Hey to all, I am testing the waters to see what my project's worth as is. I do not have the time to complete this project on my own. I'm willing to throw money at it to finish, but don't know where to take it. I live in Southwest Louisiana in case you're wondering. Refreshed engine - New gaskets, ARP bolts, OEM head gasket Sanded, primed, and bedlined engine bay and cleared with metal flake Borg-Warner 7670D Twin Scroll 1.05A/R About the car: Bought the car in New Mexico. Surface rust beneath the fenders but can be sanded out. No rust on floor boards up front. Surface rust near the back of the seat mounts but nothing serious. I the frame rails need to be repaired as there is rust damage there. No rust around drip rails, or in spare boot. No rust on or around hatch. Illumina adjustable springs and eibach springs bought for front and back. Only back has been installed, along with poly bushings. Carbon Fiber rear spolier and front splitter 5-speed manual that came with the engine Bought but not installed: New weather strip kit for whole car Eibach lowering springs (front) and tokico illumina adjustable (front) Poly bushings for front suspension I have a spare R-200 that comes along with it, but it's not worth much as I thought it was an LSD, which it isn't.

Went to the Dyno today expecting to do 5 pulls and get a horsepower number. I am planning a significant amount of upgrades soon so I wanted a baseline. This place lets you run the car yourself on the dyno. I had never done something like this before, so my first run I stopped at 5500 RPM. The second run I went all the way to 6200 RPM. Better numbers, but we thought there was an air leak. Upon closer inspection, we saw coolant going everywhere! Apparently a weird old T-fitting on coolant lines had failed. It killed my dyno session. Luckily, the shop let me replace the T-fitting there myself using their equipment and I was able to head home. But not without this interesting dyno chart! This is a 99% stock L28ET. Swapped by previous owner around 2004. The only thing not stock is that the air intake is moved in front of the radiator and there is an oil cooler. Dyno Chart Peak Power: 148.86 hp at ~5700 RPM - MEGA POWER!!! Peak Torque: 161.37 ft/lbs at ~4400 RPM EDIT: Done with 1978 280z 5-speed transmission and rear diff in 3rd gear. I'm gonna be honest - I thought there was more power under there lol. But I'm not complaining! It certainly feels like it with how light this car is. But what the heck is with everything taking a dump @5k? Action Shots: Coolant Pouring!! The busted T-fitting - wtf is this thing? Fresh T-fitting Installed! My buddy who was nice enough to come by and help!

I had a slight ticking sound in my engine a while ago and decided to adjust my valve lashes. I had no issues adjusting them, but when I put everything back in place I noticed a knocking noise coming from then engine, and it smells like its burning oil, my spark plugs are all black as well. I dont know what might have caused the knocking sound, as it wasn't there before. Could it be a collapsed lifter or a bad stem seal? I'll attach a video of the engine running, you can hear the knocking pretty clearly. This thing is driving me nuts.. I try to fix one problem and end up with 10 new ones. 20180719_194207.mp4

I took the valve cover off today to adjust my valve lashes, I tried to clean it as much as I could with simple green degreaser. Would it be safe to reattach in this condition? Or should I continue to clean it completely? The seals on the inside around the baffle plate look worn out and I'm worried some of it will get into the engine, some of it chipped off while I was scrubbing it. Is there any way I can scape off the old sealing and re seal the edges? Or do I need a new valve cover?

I purchased this dash over 5 years ago but never used it. I believe it was an alternative dash for use with Vela Rosa or Thunder Ranch GTO kits. Anyone have an idea of worth, or have a need? I'll probably ebay it. PM me with any thoughts

This came in a 240z I got a few years ago, I parted the car out as a friend of a friend wanted something for an lsx swap and my uncle has been trying to sell me his 240z for ages. The z I bought from my uncle has a rebuilt numbers matching original motor so I’m not changing it. This L28 came from a 280z and is supposedly built. Unsure what it has, could be just a cam, I wasn’t the one who put it together. N42 block, N47 head. Turns by hand. Remanufactured starter. Intake and exhaust manifolds were on until I just removed them, it wasn’t sitting exposed. L28’s originally came in 280z’s but they can be used in 240z’s with carbs, an electric fuel pump, and ignition control (I have a Crane kit and a GM unit people often use available). $675 6-1 header available separately $195. Round top SU carb complete setup available extra with motor. Located in Buffalo, NY, I’d drive across the border in exchange for a bottle of vodka from the duty free heh Text or call 716-7two5-5366 -
I'm looking to refresh my suspension for my 75 280z. Looking for coilover and aftermarket control arms, preferable techno toy tuning but open to other brands. I'm also looking for an R200 to swap in for my stock R180. Let me know if you have anything that you are looking to get rid of. I do have so parts to trade if you are looking for Retro-spec fender flares, 240z calipers, 240z inspection lids. thanks -
I just picked up this badboy about 2 weeks ago. Runs strong and shifts smooth. Has a Corvette LT1 engine with matching 4-speed auto, engine has intake, larger throttle body, competition cams, headers, power steering. Suspension is okay, seems to have been refreshed at somepoint but I'm thinking of going the coilover route and some aftermarket control arms to push back the rear wheel a little. Also looking to change out the wheels at some point but one of the biggest disappointments is the stock R180 with Open diff. Whats the cheapest way to get an LSD in here, i think its a 3.54 and seems to work pretty well for all around driving running about 2500 RPM at 80 mph but i'm not opposed to a 3.7. I'm considering welding the 180 to keep it intact while i figure out a r200 LSD swap. Any advice is appreciated.

Hi all, I just joined the forums. I bought a 77 280z a couple of days ago and I'm having trouble passing emissions. The previous owner installed a megasquirt EFI which wasn't really the issue during the test. However, some vacuum lines are missing. The EGR valve isn't connected to anything and the vacuum line diagram shows that I must have a BPT valve, which I don't. Would it be ok if I connect the EGR valve directly to the intake manifold? The other issue is the purge valve on the carbon canister isn't connected to anything either, form what I understand, it should be going into the throttle chamber where you can see that it's plugged in Thanks!

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. -
Wanted: 240z, 260z, or early model 280z. I need one with all glass and a body with no major damage. Rolling body with a dashboard is a big plus. Im located near sumter sc, and can have family look at cars near louisville ky.my max price range is 8k.

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.

This is a build thread to document the progress on a 1977 Datsun 280z 2+2. The previous owner had started stripping the car with intentions of restoring it but it ended up just sitting in a storage container. Before that, the car sat in someone's yard because of a lien against it and eventually a tree fell on the back portion busting out the rear glass and leaving a nice dent. Because the car has been sitting for so long, it has a bit of rust but nothing structural, like the frame rails, is damaged. We've never done any car restoration work before so any pointers would be appreciated. The long term goal is to swap a LS v8 engine (probably a 5.3L or 4.8L), upgrade the suspension and brakes, and have a solid daily drivable Datsun. Below is a list of what we have done to the car already: -Stripped the interior and exterior -removed the sound dampening material with some freeze spray and an air chisel -removed the engine, transmission, and engine bay wiring -misc metal work (cutting out the usual Z rust and welding in patch panels) -coated all internal frame rails and cavities with east-woods internal frame rail coating or POR-15 Here is what we started with. Inspiration / Goals Pulling the engine - relatively easy. When you don't have a load leveler, you just use screw drivers to make sure the chain doesn't slide! Hopefully, the steering rack will be salvageable. Cutting out the rust (floor pans, battery tray, and a big spot in the bumper area) Here's some of the welding / patch panels. We used weld through primer so the the welds won't rust through. Battery Compartment The front nose area - patched on both sides driver's side floorpan (not nearly as bad as passenger side just one patch panel near the seat mount). Passenger floorpan - we fabricated a floorpan that was mainly plug welded in place and also replaced a rusty spot in the trans tunnel. a shot of some POR-15 rust convertor work underneath the cowl panel. That brings the project up to present time, lots of work to do still.

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!

After looking everything over and doing some digging I came to the conclusion that using 65 mustang hubs on 240z spindles is not a cost effective solution for big brakes. I am now looking into a ball joint adapter that bolts to the control arm of the 204z and uses press in 2014 mustang ball joints. I intend to use this in conjunction with 2004 Subaru wrx coil over struts to allow the use of 5 lug 2014 mustang hubs and brakes. Which are 5x114.3 The intent is to have the outer wheel mount flange be pushed out roughly 35mm.... effectively converting our cars from a "zero offset" wheel to a "plus 35mm" wheel... aka just like the 300z and the 240sx, Toyota supra etc... It's a front steer, rear caliper spindle just like the stock 240z, once I know what the bump steer geometry will be I will have a clearer picture of things. Someone could use a widebody or flared setup if they chose to run a zero offset wheel, or use cheap and readily available 350z wheels and have stock track width. Let me know if anyone has any input on this. Good idea, bad, etc...- 90 replies

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.

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

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.

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!

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

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.
