    So I made a laser alignment tool based on a few Ideas I gleaned from the forum. I made a slip collar that fits over the CD009 output shaft that holds a 45ACP laser bore setter. I'm using this for the horizontal alignment. Works well. I made a target that has a couple of alignment lines. The bottom is parallel/perpendicular to those lines so you can use a level to get it plumb. I then proceeded to drill so many holes in it that it's almost useless:) The key word here is almost. That was a far over to centerline as I could get it. I need to rework either the Diff mount or the trans mount to get it any further but it's only about a half a degree so I may live with it. I'm running the Technoversions RT mount and I switched to the top mount instead of the stock bottom. This brought the pinion angle down to 2.8 degrees. The transmission is at 2.9 degrees so I'm pretty satisfied. Hard to tell if it made much of a difference but the math says it should.

    As I mentioned on the previous page, a prop valve in the front is never a good idea. As brake pressure increases, the proportion of braking done by the circuit with the valve decreases. With a valve in the front, the harder you hit the brakes, the lower the percentage of front brakes you get. This is not good, because the harder you hit the brakes, the more weight transfers to the front wheels and off of the rears. So the wheels with less traction get an increasing proportion of the braking effort as you step on the brakes harder and harder. "Proportioning Modifications We could start this section by clearly stating that you should not modify your proportioning valve. But, what fun would that be? In all seriousness, making changes to the proportioning valve to effect brake bias should be left to those with the proper tools and measurement devices, but if you have tweaked your vehicle beyond recognition, this may be your only solution to restore a sense of proper bias to your braking system. We’ll start here with three of the most basic rules regarding proportioning valve installation and selection. 1. If you have the deeply-rooted need to install your own adjustable proportioning valve, be advised that they should NEVER be installed if the factory unit is still in place. Proportioning valves in series with one another can do nasty, unpredictable things! 2. If you have the deeply-rooted need to install your own adjustable proportioning valve, be advised that they should NEVER be installed in-line to the front brakes. The effect would be to make your vehicle rear-biased before you could say “terminal oversteer.” Front brake line pressure should always be left alone – only the rear pressures should be considered for proportioning. 3. In all cases, the basic brake system balance needs to be close to optimized to start with. This is the only way that a proportioning valve can be effectively utilized. You should never assume that simply adding a proportioning valve will address all rear-bias conditions, as even the best proportioning valves must be well-matched to the target vehicle." https://www.apcautotech.com/getmedia/d958a29e-4ebf-41fd-931f-bf7e4451801b/brake-proportioning-valves.pdf

    The plan was to do some track days this year, so I needed some brake ducts and an oil cooler. I sold/bartered a set of series 1 scooped backing plates I had for a set of normal ones. No need to cut up the rare stuff. Took the new backing plates, cut them to 8" diameter, took a 3" exhaust collector and modded it to fit the cut down backing plate. Welded, drilled holes in the duct hole and then used cut off wheel and die grinder to open the hole in the backing plate up. Also took a section of the rim of the stock backing plate and welded it on for stiffness and to close the gap between the backing plate and the rotor vents. Doesn't look all that wonderful but I think it's going to work well. 1 down, 1 to go, then can modify my front end for the scoops and hook up the tubing.

    Hey Guys, I have been trying to figure out what I wanted to do for color uniformity on my datsun. I really wanted to get the car sand blasted and do a complete overhaul, but after swapping a l28et in the car, building and installing the megasquirt, and all the other tid bits... I was way over budget to say the least. To be cost effective I decided to do a vinyl wrap. 3m vinyl to do the whole car was only 500 bucks! The car itself was in no shape for vinyl. It had chips, dings, rust, you name it. I had to do all the body work to straighten it out. Here is some before pictures. The paint had to be sanded or removed to metal and bondo was applied. First time ever really doing body work and it looked OKAY. I did have a professional come and do the final things to the driver's side fender and door. Lots of chipping paint that needed to be sanded. After things were sanded and looked pretty good, spray can primer was sprayed on the trouble spots, then sanded, then black rustoleum, then sanded. Finally I wet sanded the car with 1000 grit and made sure all surfaces were smooth. Then the fun began. Vinyl took around 20 hours to finish in a weekend. This did not include the headlight buckets, turn signals, or cowling which I am still trying to figure out. The car being unibody caused issue. The rear bumper section is 1 piece which is then overlapped 1 inch by the quarter panel which is then overlapped by the roof. Knifeless tape was key to get smooth lines. The hood is harder then it looks because of the round center bubble. Really have to stretch and pull to get in on right. Also getting the vinyl to stick properly on the back required cleaning all edges and even applying loctite super glue.... I know not the right way, could use primer 94, but actually works! Just don't get that near any exterior surfaces or you will leave marks on the laid vinyl. Fenders are one of the easiest. Tucking around the wheel arch was a little tough. Make sure to clean these back areas so that no dirt is in between were you want the vinyl to stick on the inside. This is were I started to notice that my rusto paint would start to peel if we kept taking off and re-applying the vinyl. There are spots were you can see this for sure, but oh well.... it cost 500 dollars. Also you would get specs of shit for the same reason, small pieces of paint peeling up. Moral of the story. Only works on really good paint or paint that is strong against the body. Should have spent more time in that regard. Rear bumper area was pretty easy just a flat piece. The quarter panels were the most difficult. Trying to get around the rain gutter was a challenge. We accidentally cut the vinyl and had to pivot to a new plan regarding the roof. Paint was peeling up if we removed it so we went with what we got. If we were to peel it off... I would have to sand the whole quarter panel over again. Made it work, just needed to add an intermittent piece between the quarter panel and roof. Getting around the back taillight area was a little hard as you really need to stretch it. I assumed the inner edge would mostly be hidden by the taillight panel, but more is exposed then I thought. Might try to adjust this better. Roof and hatch were also pretty difficult. If you have old shitty gaskets around the glass. CHANGE THEM. Tucking underneath that shit would have been way harder than it already was. I got new rubber were needed and it was way worth it. If you mess up on a part like that... there goes 70 bucks in vinyl to redo it. Tucking worked best with knifeless tape in my opinion. Don't forget the sides of the windshield... I used a small inlay for that. Also the bottom area below the door is an inlay. Here is the vinyl result.... get it... vinyl result Might keep the windshield wiper area black... its scary when you see all the spots were it needs to be cut! Here is a picture of how we did the inlays from quarter panel to roof. It turned out pretty damn good if I say so myself. I have learned a lot about this process as I went because there is not too much info about unibody cars. I would say that this is a pretty difficult job and very tedious. Details are important, missing a cut or making a mistake can make it look bad. We had mistakes, bumps, paint chips you name it, but the point of this was to get the car looking good for a couple years for cheap until I am ready to get the car painted. What I would suggest if you want to do this... - Make everything really smooth. - If painting, take your time and get it to stick well. Paint peeling and sticking to the vinyl was the biggest issue I experienced. - Have a friend. My dad worked the whole time with me.... I can't thank him enough. I did a trial hood before all this on my own and it took 2 times as long and looked way worse. - Plan out all the cuts before you apply. Thought I would share my experience. If you have any questions about it let me know. I hope to reassemble the car in the next 2 weeks.

    Thanks to everyone that purchased a piece of apparel in the fundraiser to help @SuperDan with operating costs for the site! We sold a total of 88 shirts with a resulting profit of $1202.19, which I just sent 100% of to Dan. It won't show as a donation because I sent it via friends and family to ensure every penny made it to him. This should cover the site's costs for about 6 months. Moving forward, I'll be doing an annual apparel sale with 100% being donated towards operating expenses. Each year we'll do a different promotional item since many of you now have several HybridZ shirts in your closet! Looking forward to hearing your ideas on what you'd like to see along with the shirts. Hats, beanies, keychains, stickers, etc all come to mind.

    Semantics is a big deal on this forum. It is one way that separates us from other forums. Making sure an item is called the correct name that people recognize will go a long way. If you want I can edit the title of your post which directly asks for a workaround to the combo switch. Semantically it seems to be called a multi-function relay. The relays themselves seem to last quite a while, I'm still using several stock ones in my 71 that was in use till 2010. I would suspect as miles pointed out it may be the switch contacts on the stalk going out. The hazard lights switch has its own set of wiring so it may be acting as a red herring if you are using that as the reasoning in your train of thought. I suggest taking a breath, people are here to help of their own accord, it may be frustrating to seemingly answer the same question or when someone is caught on a seemingly unrelated point, but realize we need clarity to try and help. It may serve to help their train of thought, and it may seem tedious, but given the free help, maybe try being accommodating? It may serve better to have a post where you clarify exactly what you are looking for that you or others can refer to someone asking a question in the post. I can't answer as I've only looked at the early Z wiring in detail, but it seems odd for the blinker wiring to go through the floor so I can identify with others as to the confusion. I'm finding a note that the part number was used for a fuel pump relay, might be something else to check. I do know the pins are a standard spade connector so you could wire in a modern relay if you can pin out the contacts and make little adapter lengths, I've done that for some older plugs before. Identify power, ground, switch ground, switch power, and output. Then you can use any modern automotive relay.

    katman? Where the hell has he been for the last 10+ years? Oh, that's me, back from the dead. That thread may have been on improvedtouring.com. Assuming your friend also has to run the stock drum brakes, here's how we made brakes last in an ITS car, which at the end of its development was probably as fast as any CP vintage car. I don't know what compound Carbotech has today, but back then the HT-9 was the only thing that would hold up to the heat on the front. The HT-10's that replaced them were not as good, but that was about the time that SCCA pissed me off by outlawing remote reservoir shocks so I quit thinking about Z brakes. I ran both the Nismo rear shoe, and the relined Carbotech shoe, I think. We cryo treated rotors and drums. We ran the parking brake so we could adjust the rears during the course of a race. That and having an adjustable prop valve so you can make the rears take their share of the load is critical. If you aren't turning the friction surface of the drums blue, then you ain't there yet. Scour the junk yards and find every Z drum you can find and have them turned and expect to rotate in a new set every weekend. Up front, don't fall into the trap of using a pad that maximizes the pad material, in other words instead of this | | , you want this \ /. The outer radius of the rotor runs hotter because its going faster (linearly) and wears the pad faster. Nothing worse than having to pump the brakes every corner to take up the slop from tapered front pads, maladjusted rear shoes, and expanded rear drums. We drilled holes in the backing plate on the rears for some cooling, but not much else you can do back there. Up front we ran three 3" ducts on each side, one to the hub area of the strut to cool the bearings, one to a custom "can" that blew air on either side of the rotor, and one that blew into the caliper overtop of the pads. That one was tricky to make as there isn't a lot of clearance between the caliper and a 14" wheel that we had to run. I also drilled a series of small holes around the periphery of the pistons just behind where they contact the back of the pads so air could circulate behind the pads from the aforementioned duct over the pads. PM me and I'll send you some pictures.

    It's a spacer for the flex plate. You need to remove it anyway to mount your flywheel. Pretty sure it just pries off easily. Then the seal will be exposed.

    I noticed some traffic on my web site from HybridZ and was pleasantly surprised to see a thread opened on the CV axles. Thanks John! Mods, I'm new to this 'vendor' role, please let me know if I'm breaking procedures etc... I'll keep this theme to simply answering some of the questions raised above. Please don't hesitate to add questions and I'll continue to answer as best as I can - w/o giving up too much R&D. "...he seems to be quite a regular in the "Dime" community" - that I am. For the past 7 years I've been a proud owner of a 1972 Datsun 510 2 door, orange. I also own a 1976 280z that currently being built up into another fun toy and R&D test bed for future products. Much of my involvement on 'The Realm' has been sharing in my experimentation (Yamaha R1 carbs on a KA24e and MegaJolt EDIS ignition etc...) and learnings. "..I wonder if he is just cutting flanges off old u-joint axles and welding them on to "CV" axles..." - nope. I manufacture brand new adapters/flanges, accurate up to 4 thousands of an inch on centering/mounting to make them dead smooth. The flange's bolt-hole placement is left to CNC machining for repeatable accuracy. "...Not sure that they're much better than a u-joint axle though. What's the benefit?" - Several benefits: As the U-joints in our axles fail, finding replacements has been difficult, at least for me. Also, with lowered Datsuns, the larger angles within the axle exaggerates a U joint's inability to rotate at a constant speed. These newer CV axles (short for Constant Velocity), can rotate at more consistent speeds with larger angles. The end result is a noticeably smoother ride - even for Datsuns with seemingly fine stock axles. Another reputed benefit is more drivetrain efficiency and a couple percent increase power to the wheels. "I wonder where the came up with the torque limit. Breaking welds? " : A LOT of engineering went into these CVs - down to shear calculations, metals selected for the adapters and how it interfaces with the CV, impacts from tempering, redundancy in fastening etc... Calculations showed that the fastening/welding technique is ~20-30% higher than the stubs at their weakest point. Back to the question, the torque limit was placed because that's the approximate OEM limit that the axle is designed for, and I wanted to limit anyone trying these axles on over the top machines. As previously posted the axles are comparable to the Subaru STI which are quite capable. My guess on the weakest link now lies in either the axle splines or the shoulder/D bolts themselves. " Being that the stub axle is such a weak spot..." - I'm not sure where on the stub you are referring to but I do offer an integrated stub CV where an OEM STI stub is directly fastened onto the CV housing - in 3 different manners (it's NOT coming off!). It's really slick with only 4 bolts to fasten the axle onto a clip-in diff setup. A similar R200 version is in the plans for this spring as well. I hope that answers the questions. My CV axles are designed to fill a niche market and not directly compete with existing products/vendors. There are already several options for owners with massive HP and/or heavy track duty needs. My CVs, and frankly the basis of all my future products, are intended to be an affordable & original solution that offers a level of reliability (read: lack of maintenance) you expect from a street car, be it stock or with a moderate swap/upgrade powerplant.

    Well guys, I finally solved the issue - Since I got my car without any keys and ignition lock and switch, I had ordered a replica version on e-bay. Once it arrived I looked at the connector and the switch (5 pins,1 missing) and figured that it was all correct. I also checked the details in BE-26, with the B,S,A,IG pins, and the one not named in BE-26, marked as "R". Measured the signals and all seems correct. - After having run through the fuses, relais, and wires, i went back to the switch again. After studying the schematic below, I figured I better measure the signals with the connector in the switch. There I found out there was no voltage signal on the "S" with ignition on START. Checked the schematic below again, and found out that when I would swap out 2 wires in the connector, all would be fine. So thats what I did, I swapped the White Red wire, with a Black Blue one, and starter cranked up right away. Issue solved! So for people getting replica ignition switch watch out for this mix up between R and S. - btw, anyone know what the Black/Blue wire is for? as I have now switched that one in the ignition switch connector. Thanks for the help jhm! cheers, joost

    Quite a few things wrong with that Tune. No wonder you are having issues with AE. Made some revisions to. 1: AE settings. No where near correct. Made several changes there that should be positive. 2: Target AFR table far too lean at low RPM. VE table greatly affects transition off idle. Going too lean creates a bog. With proper Ve Table, less AE is required. 3: You were running Alpha N. MS3 has a special Fuel algorithm for ITB's. I have enabled that. 4: Spark Table needed some work 5: I've noticed that you have your O2 feedback control disabled. I have enabled it but set proper settings and filters on it. Send me a PM with your E-mail address and I will send you a touched up Tune. This is just a Baseline . but should be an improvement. I also do Remote Tuning and offer full Tunes built for your particular engine specs.

    I know everyone knows this already but 250hp/300ft-lbs is handled easily by the stock R200 long nose. Until the 8.8 became the hottest topic, the long nose R200 was considered just fine for all mild V8 swaps and some fairly upgraded ones too. Drag racers have run the R200 well into the 11s without issue (other than the lack of LSD options/ratios).

    Machine work finished! I can relax a little:) Just got done with their first bath. Still need de-buring and edge finishing but the majority of the work is done. The VCT holes are drilled and tapped but they haven’t been drilled all the way through. Easily opened up with a drill if needed. The head has provisions for three sub plates. Timing chain idler, upper tensioner and a slack side guide pivot. The idler and tensioner are connected to the oil system and o-ringed. It is getting really crowded in there with all the oil passages, head bolts and cam tower bolts. Next stop vacuum resin impregnation.

    With all do respect newzed you have contrbuted nothing new to the solution of the problem that I had not already addressed many weeks back with DSS. I may not be using terms that agree with you.... I said “bind and won’t turn” and you prefer “won’t spin”. Your suggestion of filing off a dust cap is impossible as we are talking about solid billet machined parts that are meant to be to spec. You just can’t take a file to this stuff and call it good and I don’t own a lathe. I purchased these parts at great cost per DSS selling them as bolt on and in regularly use on many S30 Z’s. They have since admitted that they have NEVER had this stub axle on 240Z and admitted that there stub axle was previously copied off of an unknown Datsun stub axle they were told was an S30. I have supplied them all of the measurements using my mics and calipers for the risers so the bearing would fit per spec. Unfortunately, the first riser was not machined to measurements I provided so they did them a second time, this time per my measurements and they are perfect. Great, however the billet machined shoulder then cam into contact with the housing and again would not spin. Soooooo I sent them a stock 240Z OEM stub axle along with their axles with the understanding that DSS would machine into the billet stub axle the proper recess and width allowing the stub axle to fit as OEM with the stock stamped dust cap. DSS sent the axles back to me with shoulder machined down but without the necessary recess. I called them concerned they still would not fit however, per their instructions, bolted them back up as they were “within .005 tolerance of OEM”. I bolted them back up and they continue to press against the housing and will not spin. I called DSS with the bad news and they said “sorry, we didn’t think the recess was that important”. My response was “why didn’t you just machine the axle to match the OEM one I sent”? There Response- “Im not sure i need to talk to the machine shop”. As of this afternoon, DSS has requested I send it all back one more time and they will make it right. I’m going to give them that opportunity again as I am to far into this to just turn back. So, after month of emails, pictures, and sourcing hardware to fit (since the supplied hardware hits the differential on the adapter side of this conversion) I am again hoping that DSS machines these stub axles to OEM spec. Keep in mind, this is advertised as a “bolt in no modification kit”. Im really not offended that I’m not making sense to you. I’m offended and ticked off that I was sold a product that has never actually been bolted on to a 240Z and that I have been patiently (admittedly sometimes not so) trying to help them produce a useable product from the other side of the U.S with phone calls emails and pictures. The final straw is sending them an OEM axle with the instructions “make a copy of this” and it still came back machined wrong. Every point you have made regarding bearings and risers and clearance I agree with fully and in fact I communicated to them to fix those issues as they arose. It’s been a long process. I’m sorry I can’t satisfy your deepest need for every piece of communication and I honestly can’t tell you why they keep getting it wrong. Funny thing is, they can’t explain it either, but they sure as heck are not blaming me. Lee thanked me for my patience with all of DSS mistakes. Getting into a war of words is not my bag. I’m bummed out this crap is clogging up the forum. I apologize if I offended you. I’m really just a hard working guy that loves Z’s and gearhead culture in general. I’ve been building and racing for most of my 50 years of life (first kart and motorcycle age 5) and building cars in my garage is my therapy..... supposed to be fun. Given all my frustration with this purchase, i just needed a place to vent and I really want others to avoid the same. So hearing that I’m a whining complainer that doesn’t know what the hell he is saying and is incompetent to turn a wrench hits where it hurts to be perfectly honest. Agree to disagree is cool with me, time to let this squabble go. With respect, Jim

    While the Z is at my place, my Bodyshop gave me some homework: To completely strip the chassis from all the seam sealer, undercoating, bondo and paint so that it's easier for him to remove old welds and weld new stuff... started by removing the biggest chunks in the front inner fender area with a spatula. but after an hour i realized i need a faster solution. After a bit of research, i found this tihng called Turbo-Igel (Turbo Hedgehog). The name comes from the "hook" style spikes that remind of a hedgehog This thing works absolutely brilliantly and isnt really agressive to the metal due to it's unique shape. The problem is, after 10 minutes the effect really starts to weaken since the hooks get dull. but you still can u se it totally for about 30minutes at a maximum speed of 3500 rpm. then all the hooks are gone With two disks i managed to get this much done in approx. 2 hours of work: Well and while the car got cleaner, i got dirtier And i removed approx 3-4 kgs of Bondo / Paint, underbody coating, seam sealer etc.. Still a lot to do. for me and the bodyshop. can you see all those terribly cheap repair attempts from previus owner? And rusty spots? And dents where there shouldn't be? Well... i've come too far to stop now, i guess

    Why do you want disc brakes on the rear? I ask because any kind of brake on the back is still only get the set amount of brake fluid pressure that the M/C and stock proportioning valve will allow and that amount is just right for the stock drums. Or I should say just the right amount for the rear wheel cylinders, it is engineered to be a balanced system. Putting disc brakes on the rear with everything else in the system being stock could lead to the calipers not applying enough pressure making stop times longer or they may lock up the rear sooner than the front which really is not a good thing. After having tried all the usual brake combinations that are popular for 240z's I can say with conviction, If you want better brakes then remove the stock balanced system and replace it with another balanced system, a system that has been designed to work together.

    I think that they're showing "boxed" body components. Integral reinforcement as you said. Like the rocker panels are one of the most important structural elements of the unibody. People often overlook that area when dealing with rust. The "frame rails" are just added stiffeners. They'll replace the stiffeners and leave the rusted out rocker panels. So, when looking at the cowl, or any body area, look for those reinforced areas. But, I'm not a structural or automotive engineer, so don't put too much weight in to my words. Somebody had a thread on the site where they really went deep in to how to reinforce the body. I think that they even built a framework to load the frame and measure deflection. It might be in an FAQ area, or might be found by a search.

    Progress has been slow but the car can be pushed around right now Work on wiring up the gauges, wiring harness etc is basically under way now. The frame for the fuel cell needs a couple more brackets and powder coat. Getting pretty close to sending back for paint Silicone intake hoses are probably coming out...but wanted to show a picture of where it is at.

    Okay, now driven on both setups i can tell this mod is way stiffer than original. For normal winding roads, brisk thru roundabouts normal setup is more balanced for my use, but on highway driving faster stiffer feels bit safer. Wet auto-x track would be fun to test on both, i think stiffer would understeer a lot.

    Twin turbo and twin injectors are a bit out dated lately. Has it been a while since you have looked into tuning? Times have kind of moved on with more advanced ECU's that can handle large CC injectors at low idle, something like the 750cc you will most likely require shouldn't need a smaller injector for idle or anything of that nature. Twin rear mount on an inline 6 just seems gratuitous. A modern single turbo will have adequate spool characteristics or you can cheat with a QSV, but running two same sized turbos ala FD RX7, TT Supra, or the TT subaru that spool one then both at different times is quite a chore when modern compressor housings, twin scroll, QSV and such will bring most to a more than usable power bound. Most rear turbo setups are due to proximity of a rear mount engine, space, laziness, or style. Engine is in the front, you have ample space, the fabrication to mount the intercooler back there and the ducting to bring it back forward would indicate no lack of effort, so short of style it seems kind of silly. Echoed above, find the ecu the shop or shops around you will tune on unless you have a tuner or plan on doing it yourself.

    Wheels for setting up your car 😉 The items pictured are more like hub stands as they don't resemble wheels It goes something like this - jack car up - wheel off's - bolt hub stand's to hub's in place of wheel's - lower onto corner weight scales/set up patch - give it a good shake to settle the suspension - adjust away to your hearts desire, without having to fight your way around the wheel that's normally in your way

    Alright, so we're going to try this again. Utilizing the rusted roof car as a parts car now I was able to find a early 260 that I'm going to use as my project base. It is in WAY better shape as some did a attempt a repairing the floors and there are just a few small rust spots here and there that are repairable. So 240 V8 build take 2.

    Here's the latest on the bracket saga. I tried three sets sourced by Summit Racing, and when the third set (made by Grove) was going to hit stuff, I bit the bullet and fabricated (actually, I modified the last set I got). The folks at Summit were super about the returns, but when the third set didn't work, I felt embarrassed. After all, three times! I used 1/4-inch aluminum plate to make the modified parts, and used as many parts as I could of Grove's stuff. The compressor is off now, but with both in place, I measured and measured, and I am now certain--well, almost certain--that these will work. Here are some photos.

    Posting from another forum by the user sfm6s524. I am the seller. You guys can ask questions here or contact me by etsy as i check that more. Original etsy listing here: https://www.etsy.com/listing/668444381/datsun-240z-260z-280z-sun-visor-bracket?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=car+sun+visor&ref=sr_gallery-1-5&frs=1 On a 71 240 Z I have, the piece that holds the sun visors in place that mounts beneath the rear view mirror, broke on the drivers side. It was pretty annoying having the visor flop around, and I finally took the visor off until I could locate a replacement part. Searched all over the place for another, no luck. Finally saw one on Etsy from a person who has a 3D printer named PlasticWiz, figured I'd give it a try. Removed my old one, which basically disintegrated while trying to pop it loose from the vinyl covered roof frame. Sanded the new ABS piece a bit and painted black. I suppose the "print lines" could be removed completely with a lot of work, but for this car I just wanted a functional piece. Here it is mounted ready to pop in the rear view mirror. I've never used a 3D printed part on any of my cars, but I must say this really did the trick for a difficult part to find. Anyway, just thought I'd post this since I couldn't find any recent help on this part. I may order another for my other Z just in case...

    What year S30? The early-year cars came with open R180s, and some of the last year cars came with R200s. I don't believe any of the standard differentials were LSD from the factory. Most people putting down serious power in straight-line applications use the R200...it's quite a beefy unit. There are quite a few threads here about the different options available, so search and you should find all the info you could possibly want, and make sure you check out the pinned threads too. Hope this helps.

    Well, I did want to adjust the fuel and timing maps a bit to get rid of a few drive-ability issues since I'm not running a stock block. Also wanted to pull some timing before turning the boost up again. I also have an 84T ECU I've been scavenging components from it, I'll probably dump the ROM at some point as well.

    Socorob: If you lowered the car with springs or Coil overs. Did you shorten the strut tubes? If not you are probably running out of suspension travel and hitting the bump stops. Common problem. Then you have to put Box Car springs in the thing to keep it off the bump stops. Not ideal.

    it's all a nice exercise... Have titanium valves, retainers, spring keepers? Well then lighten that reciprocating end and run a lighter spring, you might be good to 24,000 rpms! stock nissan rockers on our bonneville engine were stable to 13,000 rpms in our testing. I think valve, spring, and cam profile selection play a much more critical role. If you note the E-Motive guys polished theirs similar to TimZ. We didn't even do that, though I have in the past on other engines (Yamaha....)

    Found the problem. There is a relay attached to the motor which, I believe operates the parking system. Mine was toast. I bypassed it and now motor operates as long as I want. Just have to time shutting off wipers to park wipers correctly.

    Yeah, regarding the boxer swap, until someone actually gets it done and running, I'm not counting it. The purple V8 car you're talking about is the same one I was referring to, BTW. It belongs to a guy named Kevin Mackrell. I managed to find the other one I was talking about. The track width and wheel base make it look really wonky. http://jdm-culture.com/adree-hamid-r32-in-disguised-s30-240z/ Also, while looking, I managed to find mention of a third AWD Z, posted on this very forum. This one actually looks really impressive. Fourth post, by OlderThanMe.
