  1. Hello, I am new to this forum. So far, I have found the search function doesn't work as well as some other forums I am on. So if this topic has been beaten to death I apologize, but I did look (both on here and through google). As many posts here have acknowledged, the stock alternators on the S30 leave much to be desired (particularly at idle). I found sites discussing swapping to smaller diameter pulleys, but only in a generic sense. Therefore, I don't know what the alternator on a 1975 280z can handle ...or if it would even help. Has anyone tried putting a smaller pulley in to increase the idle alternator RPM? What are your thoughts and what size might you suggest? Obviously, it will wear faster and I don't want to over spin it. On the note of wear, what do you think of swapping for a clutched pulley while I am at it? If no one answers, I will just try swapping in a internally regulated 70-Amp alternator from a 1986 300zx.
  2. Hey, I'm new here and did a search but didn't find a real answer. What's the best place to buy repair/ patch panels and fenders. I live in the mid-west and have a 76' z with some rust. I know Black Dragon parts are foreign produced, MSA says on some of there parts that they are made in the USA and I really don't know anything about British Victoria parts. Are there other sources? Of the ones I mentioned does one provide a better fitting panel and fender than the others??? Any feedback and input would be appreciated, thanks in advance...
  3. I've never seen a thread where someone documented how hawks mounts actually mount up and are installed. So I took a bunch of pics when I did mine for all to enjoy. Chassis Mounts Here's how the mounts look in your hand. I'll explain what each location really does as we move along. And here is the back of the plate that you must weld onto the frame. As you can see, you must clearance the frame in order for the plate to site flush again your frame rails. But before we get into that, lets see how we locate the bracket (front to back). So here is the mount just resting on the frame rail, without the backing plate, You can see now that the lower location of the bracket lines up perfectly with the lower control arm bolt. Now all you have to do is loosen the LCA bolt, remove the nut, and thread the bolt into the bracket (yeah its threaded down there). Once you have it threaded in and snugged (not tight), you've got it located front to back. So then I attached the backing plate to the bracket and swung it back into place on the frame rail. Obviously the backing plate wont sit flush until you clearance the frame. So now, mark the front and back of the backing plate on the frame like so. Now remove the backing plate from the main bracket, also remove the main bracket from the LCA bolt. Place the backing plate on the frame and mark the hole locations. Note that they will be off because you still cant set the bracket flush. So here are my marks. Let me save you some time and suggest that you cut the frame like the pic below. I tried counterboring the holes to make room for the tacked on nuts, but its harder to get the position correct. Notching the frame is easier and much faster. Now you can check to see if the bracket will sit flush. It might not sit perfectly flush, but pretty close. Heres how mine looked. If its good enough for your taste, put the main bracket on the LCA bolt and bolt it back to the backing plate. This will ensure that when you weld it, it is in fact correctly positioned. You probably want to go ahead and grind off the paint on the frame as well, I dont have a pic of that but you get the idea. Now your ready to weld. Just for reference, the side of the frame rail is twice as thick as the top. So you can get a little more heat into that side. Here's my ugly flux core madness, but it will get the job done. The second one turned out much prettier after I found a rhythm. And here is the finished product. Engine Mounts The mounts on the motor are fairly straightforward but I figured I'd show them for documentation purposes. Here is where the original mount goes. And here is the backing plate for the new Hawks mount. Dont put that lower right bolt in though, that comes later with the actual mount. And here is it all bolted together. At this point, I dropped the motor in to position the trans mount. I'll write more on that in the Trans Mount section. Here, its just to show you how the motor sits in the bay.

    Mounts to place sway bar into a 77 280z
  5. Edit - First, thank you for any replies and to anyone who read my original post. I am learning this with the FSM and two repair manuals. I used a second set of eyes to go out and triple-check that I hadn't made a bunch of mistakes. The first cylinder gets a compression reading on the gauge at about the 45 mark (if it existed). When bringing the pulley mark to zero with the help from my second eyes, I get a completely different and much less dramatic looking scenario. The timing mark on the chain is a V (sitting at 2) versus a shiny which I couldn't find before. This looks less problematic than the crazy scenario I originally posted about but is still puzzling to me as the PO's mechanic didn't work on the timing but said there was a definite issue. Do these markings look off to you?
  6. Background: Long story short, wasn't interested in cars until I got screwed over by a dealership replacing an alternator shortly after moving to Maine from Ireland. Found a '84 300zx for $300 on Craig's and proceeded to teach myself the dark arts of car wrenching, and consequently fell in love with Z cars/Group B/Rally/Hillclimbing Fast forward a few years, I picked up a 1970 240z with some track prep work done and it begun: Cars 1970 240z: 2.6l engine Mikuni ph44 carbs Battery relocate. MSD Ignition Rota Grids with Toyo Proxxes Put cosmetic (Flat Black paint), small amount of mechanical work (New clutch, relined tank, new Holley Red FP, FR, SS lines) and new shoes on the car to prep for the New England Hillclimb Association 2015 season. Work and life got the better of me and only got to one race. Car performed pretty good and the driver got a lot better over the weekend. Couple of issues raised their heads over the race weekend: Keeps popping out of second gear. Power-band not right. 1st, 2nd great to 6500rpm, go to 3rd and bogs down bad. Last two races, kept stalling in low rpm and overheating - I believe this was from running out of fuel and picking up something in the carb. Need a full roll cage if I keep racing it; wife and kids agree. The last bullet is how I happened upon the 280z. After pricing a cage and always being on the hunt for a deal I came across this 1976 280z in a wrecker yard in MA. Something caught my eye on the Craig's post - I had been lurking on Hybridz for many years and thought had seen the chassis before. Upon viewing it was indeed one of RB240zDET's builds. I was able to get the car and good price and figure the project would be worth my time. 1976 280z - as it stands: Tubular frame chassis. R33 rear subframe and R230 diff. RB20DET engine mated to GTS trans. Lexus SC400 front end. Probably a bunch more I have yet to document.

  7. Hi, my '75 280z makes a horrible squealing sound whenever you engage the A/C. If you set the climate control to vent or any other setting the noise doesn't happen, only when its on A/C with the fan on. I heard it could be the belt so I sprayed a generous amount of water on the pulleys and belt and the sound persisted. The noise gets louder and changes pitch when I press on the gas. If I get out and look at the belt when the A/C is engaged I can see the belt slow down/catch on something. I've driven it with the A/C on for a few minutes to see if it would ever stop but it hasn't. At this point I'm kinda lost as to what it could be and what I should do about it. I'd love if you guys could give me some advice.
  8. Hello all, I've had a 77 280z for a few months now. It's got a 75 L28e motor with the non exhaust lined head. Since then, I've converted it from automatic to 5 speed, 3.9 R200, decent paint job, etc. My friend and I were getting the car ready for a long trip (1500 miles) doing routine maintenance when we heard what sounded like rod knock. Well, a 2 hour basic maintenance trip turned into a 10:30AM to 5:30AM bottom end rebuild. This was 3 days before my 1500 mile trip. Regardless, the car made it with no issues!! Essentially, everything has been touched in this car except for the wiring. It runs great and is my daily driver. Now I'm looking for some more power. I've already done the basic stuff (auto to 5 speed, 3.9). I do like the L28 motor, but I have no issues swapping in something better. I am not looking for a crazy drag strip beast, just maybe upwards of 200whp with decent gas mileage (20+ would be great!). I know generally power and gas mileage don't go together, but I know some of the Chevy V8's can get you 28+ on the freeway. For a budget of $1000, what is the best way to go? From everything I've read, it seems an L28ET may be the best option. If I don't do a swap, will any upgrades to the L28 give significant gains within this budget? There are still intake, headers, megasquirt, cam, headwork, etc. My goals are a 'quick' daily driver, so I would prefer to keep the power band lower rather than higher. Torque improvements would also be nice. I'll be happy to give more information if necessary!
  9. So I had bought an S30 air dam from Japan this past summer but never got around to mounting them to the car until this past winter. I originally got air dam with turn signal cutouts because I was planning on doing front turn signal swap and going for a 240z set, now I'm not so sure. Anyway, upon install I realized that the air dam doesn't come close to the sitting flush against the mounting points near the headlight buckets. At first, I figured it might be because there's extra material on bottom of the mouth of the air dam but I assume that even after cutting it it still wouldn't sit flush on the mounting surface anyway. Additionally it seems as if the vertical faces on the inside of the turn signal cut outs aren't long enough to sit flush with the inner most edge of the mounting surface. Also when you have one side of the air dam seated flush along the fender lip, the other side is pushed away from it, which leads me to believe that the air dam's overall size is too narrow. Am I wrong in assuming that the 240z and late 280z air dams are similar in nature? I'm very close to just purchasing a fiberglass 280z air dam and redoing it in carbon. Apologies for the lack of light in the photos, I was doing this at about 11 at night.
  10. Reading at 0 throttle is 220 and at full throttle is 1238. Is that correct? Keep losing signal, have traced it through a spade connector that was loose. Once I have reset the signals is as above readings. Throttle application seems accelerated, as in 1/3 is half.
  11. So smoke started coming from my steering column one day ... My right turn signal does not work and my left "freezes" . Has anyone else had this problem with their 77? I'm suspecting it short circuited . Is there any KEY areas to check ? Any help is greatly appreciated
  12. As the title suggests looking for a z that's swapped clean would be a plus. As much as possible no rust. Willing to travel for the right one
  13. 1971 240z "Kirin" Hi there! This is going to be my little Z build. Picked her up as a gift to myself after coming back from Japan. Today she sits eagerly awaiting to be fixed up and driven.

  14. I am looking for a cheap, running and driving v8 swapped Z. It can be ugly but I do not have the equipment to do a swap. I have the skills and equipment to give it some TLC such as suspension and paint. A decent interior would be nice. I am young and broke, but will take good care of it.
  15. Hello guys, I am in the process of replacing the heater core on the 77 280z. I have removed just about everything but now I'm stuck on how to remove the cooper wire that goes into the heater valve. can someone tell me the best ware to remove it without damaging the cooper wire. it seems to be in the way of removing the side door to pull out the heater core. See the picture I have provided.

  18. ok I am going to blow through a lot of questions here I have a 1971 240Z i upgraded the alternator and now my dash and running lights stay on anytime the key is on what could cause this? Second last monday i swaped a 79 280 f54block n42 head with the biggest cam you can get without going to larger valve springs i bought the motor this way i put my brand new ztherapy 4 screw su carbs on it with the msa 6to1 header and the orignal bosch distributer and e12-80 module but it wont run right it backfires through the carbs when you rev it I did get it to run the other day long enough to set the valves at .012 exhaust .010 intake but Im not sure the coil is right it has a pretronix 3.0 ohm coil from the kit I put on the 240 motor when i got it i also tried a crane cam lx91 and it got worse so I switched back to the pretronix my plug gap is .042 i just need a starting place iv done everything i know how to do to no avail. what am I not seeing?
  19. My goal is to swap a 2007-2008 VQ35HR and 5 speed automatic transmission into my 1974 Datsun 260z. I had a 2003 350z with the 5 speed auto and enjoyed it more than any vehicle I've ever had. I still have a set of Works Bell Electronic Paddle Shifters for it that never were installed. I plan to retrofit them to the 260z steering column.
  20. Hey guys! This is going to be my thread for my 5.0 swap in my 1977 280z. A little history....I picked up a 77 280z from a guy in Texas. Its not a bad car for the price. I had this crazy idea to drop a 5.0 in it, since I've got a 1995 mustang GT as a DD. I bought a 1995 GTS with a full Cobra motor in it from an auction website and parted out the rest of the car. My dad had a bunch of Z's back in the day, and I wanted to build something he would enjoy as much as I would. Please if you like any of this, let me know! I would love to keep posting some pics and hopefully get some help and help out some other guys in the same boat. Now...lets get started
  21. I have been searching for a certain yellow for my '77 280Z as I am getting ready for paint. I am contrasting the yellow with black and carbon fiber. I cannot find a color code for the certain type of yellow I am looking for. The closest I came to deciding on a color was Mercedes Solarbeam Yellow but as I am unable to see it in person, I have my doubts that that is the right color. I am aware that the color will most likely be a pearl and I am fine with that. I'm just trying to stay away from that bright lemon yellow lol. All suggestions or advice would be much appreciated.
  22. I've bought a number of vehicles in my time, but I'm looking for specific advice here. Here's what I have: 1. 72 240z 2. n42 l28 with SU carbs (x2) 3. 4speed transmissions (x2) It needs a radiator, all the hard lines, pedals, rear brakes, seats, and harnesses before it can move itself around. Because of that, I started looking for a parts donor for all the little stuff, to get the ball rolling. I happened to find a 280z with an l28et in it and a couple manual transmissions attached. It has side skirts and bumper covers, which kind of concern me, and the engine wiring is incomplete. None of that concerns me much, but my previous experience with early Nissan EFI does. I haven't seen a reliable, effective l28et using the stock engine management. Therefore, the plan for this car would be to plop one of my SU-fed l28's in it and put the l28et on a stand as the more serious build for my 240z. Here's the question of the day: Aside from the obvious doglegs, frame rails, battery tray, engine rotation, brake line condition, etc ... what dealbreakers should I look for tonight?
  23. Finished my MS1 3.57 install but have a few issues. 280z, just figure everything stock except 420cc injectors. 1. Tunerstudio and the MS ecu lose comm during cranking. The main relay has power during cranking, maybe down to 10 or 11v but still good power. 2. No tach signal. Pin 24 (white) goes straight to coil negative JP1 is jumpered 2-3, J1 is jumpered 3-4 Would anyone recommend using one of these to isolate a good signal? http://www.summitracing.com/parts/msd-8910/media/instructions 3. Would I have better luck taking the tach signal from the oem ignition control unit? When cranking and watching multimeter on the neg side of blaster 2 coil its spitting out all kinds of voltages, 12v, 8v, 10v,14v... Everything ran fine with the carb, ignition has not been touched. And why am I not permitted to upload my msq tune or logs to here?
  24. Well my car has been at the point where I can actually drive it around for a while now but I have some gremlins which make it kind of sketchy and I want to try to pin down what my issue(s) is/are. Background of the car: 1976 280z, l28et swap Stock engine setup and ECCS, z31 coil, EGR deleted and blocked off, pop off valve removed and plugged. New battery. Alternator tests good. Brand new CHTS. New aftermarket FPR with a pressure gauge. Brand new O2 sensor. My issue lies in air/fuel ratio... I have a wideband gauge which I know isn't precise but can at least give me an idea of what the car is doing. Startup is difficult, and I'm under the impression that it's because the mixture isn't rich enough for easy fireup. Idle upon startup shows lean. Idle is also a bit high at ~1100 rpm. Not sure if that could be the cause, but I haven't been able to find any indication of idle adjustment on the L28ET throttle body like people have mentioned. The odd thing is after driving the car around and letting it warm up, idle AFR shows normal with a bias towards rich, which seems to be as it should be. Things get weirder, and this is why I think I have some kind of issue with grounds or something. Driving around normally, I can turn my headlights on and the mixture will go from slightly rich to slightly lean. Driving around with the headlights on indicate that it has a permanent issue of running lean with the lights on. I've had a heck of a time finding any indication of what could cause this specific issue, both looking through the FSM and google. I'm hoping someone on here can give me assistance since at this point I feel I'm in over my head. Thanks in advance, Pac_Man
  25. I'm looking for a 5-spd transmission from a 280z to put into my 240z. Where is the best place to find one (or do you have one for sale) ? I browsed through ebay and craigslist but didn't really find anything. Also noticed that neither MSA nor Whitehead carry them. Thank you!
