  1. Huh? The 260Z dash design is what they carried through to the 280Z. There are major differences.
  2. Yup, don't use Turbo injectors with a stock NA ECU. (unless you've figured a way to retune that ECU...)
  3. Good luck with that... When you get yours in, send me a picture. I'll send you a picture of mine.
  4. You should, the original outer metal piece of the stock bushing has to come out to fit either Prothane or Energy poly bushings. I've done several in the shop - it has to come out. I installed Energy poly in my personal 260Z (Goldie) nearly 10 years ago (and, yes, I cut that barrel out - with a sawzall (but, I'm careful) and, I daily drive my car)). Please don't hit that with a hammer anymore.
  5. I think my trigger angle is about what you ended up with. The ECU needs to know TDC is coming BEFORE it actually happens and not just because we set our plugs to fire before TDC. It also needs time to make the calculations before the events are to happen. Like stated above the important part is not necessarily the trigger angle (as long as there's plenty of time before the event is to happen) but that the actual mechanical timing is the same as the reported timing from the ECU in TunerStudio. I don't think you need to worry as we have set up MS2 and MS3(X) boxes to run on both single coil and
  6. I really can't tell from either of your pictures. The mirror base should be centered in the "valley" just below the window trim and just above that final bend in the door skin (the bend that follows the front fender top curve and continues the full length of the car over the wheels on the quarter - the classic "Z shape" body line).
  7. Did the supplier tell you exactly how to connect the new harness to your existing harness(es) wiring? Megasquirt in an S30 is never "Plug and Play". The wiring to the GM coils and/or number of wires used has nothing to do with the CAS wiring. The CAS supplies a "tach" input to the ECU - it just supplies the ECU with the engine speed. BUT, until the ECU "knows" the engine is indeed turning, it can't do anything - so the CAS input is critical. This signal is displayed in you tuner studio gauges EVEN IF the engine is not running. When the engine is cranking, IF the turner studio gaug
  8. Three pin connector on each side. Should have a Black, Green/Black, Green/White wire. It's the Green/White wire.
  9. Ya, I don't understand why he's wired the coil and electronic ignition module always hot. The stock B/W delivers battery voltage to the coil at ignition ON. Connecting the red from the electronic ignition module to the coil "+" provides power to the module at ignition ON. You don't need more than that. But. I also don't understand why wiring it that way would cause your fuel pump to run...
  10. Here in the U.S. the 1984-1988 300ZX (Z31) with factory A/C used a Hitachi MJS170 compressor. The 1989 Factory Service Manual lists a model DKS-16H (Diesel-Kiki make). You can get the Factory Service Manuals for the U.S. model Z31 at nicoclub.com...
  11. In Tuner Studio, be sure to set Baro to Initial MAP Reading. My L28ET idles at around 35kpa. The default settings in Tuner Studio will likely not make changes at idle. Check the "Advanced Settings" tab and see what limits are set. Autotune will only make changes to the table within those parameters which generally include a minimum engine temperature, a set kpa (load) range, and a set RPM range. I think idle normally falls outside the default ranges. There is also an Idle VE Table you can work with. If you have followed the "Setting Up" steps in the documentation, you really
  12. Yup... Chances are you'll need to get to a different engine management system at some point. Read my posts over the last 9 or 10 years and you'll see what we mean. I struggled with the stock ECCS for years before I decided to change. I started with an Infiniti M30 ECU swap with Nistune (much the same as a 300ZX only Infiniti - so, better - and my son's '76 280Z L28ET still runs well on the Infiniti ECU (also there used to be a bunch of M30's in the yards here in Phoenix - not anymore...). I tried a VE30DE ECU for COP at one time and ended up with an MS3X. There are any number of good options o
  13. Yes, that's the electronic ignition module for the 280Z. It needs to be disconnected (removed) as I said above. But let me simplify this: ALL you need to spark an L28ET with a stock 280ZXT coil and ignitor is: - Black/White (constant battery voltage (+12v) at IGN ON) to top of "T" (2-pin connector on ignitor) - Yellow (Y/W - who cares) to "leg" (bottom) of "T" (2-pin connector on ignitor) FROM ECU pin 5 - The coil bracket must be bolted to sheet metal (meaning it HAS to be grounded). - The ignitor -> coil wiring needs to be as stock 280ZXT (meaning: Bl
  14. The '77 flywheel will be 225mm and the L28ET flywheel would be 240mm. There's a reason for the difference - the L28ET makes a lot more torque... I tried using a stock early Z clutch / flywheel package when I originally did my turbo swap, but the clutch slippage made me move to the 240mm turbo flywheel and an Exidy clutch package.
  15. The "T" connector on the Ignitor does NOT have a ground. (the ignitor gets it's ground from the bracket which should be connected to the body) It should be Black/White (+12v at IGN ON) on the top spade of the ignitor connector and ECU signal (pin 5) on the leg. The ignitor then feeds +12v to the "+" coil via a B/W. There shouldn't be any another connection to the "+" side of the coil. (Stock 280Z will have a B/W in the engine bay harness that goes directly to the coil "+". The turbo engine coil is not wired that way - the B/W goes to the ignitor. The coil "+" should already be wir
  16. Do you have the engine running currently (or have you had it running)? (I know it won't run without the AFM... my question is have you either verified the engine runs well with the ECCS harness that you have (perhaps by mocking it up on a temporary basis)… ) Obviously it's yours to do what you will, but I would caution against cutting anything up to make a permanent AFM mount if you haven't thoroughly tested your ECCS system and you are satisfied with it's operation.
  17. When I had such a thing, I didn't "mount" it. It just had to be hung as part of my cold air intake. I didn't have an intercooler at that time so that made it a little easier. I feel you, the logistics are tough. You may not want to hear this but your best option will probably be: don't use an AFM.
  18. I have to agree... I ran the stock 3.36 R-180 in my early 260Z for years (behind an L28ET) before swapping to a 3.54 R-200 - and an L24 doesn't have anywhere near the torque of the turbo motor. It is completely do-able however - a bit of a pain, but the swap is pretty straight-forward as described above.
  19. But, to answer your original question: No, you do not necessarily need to install an aftermarket fuel rail...
  20. Why did you install 430cc injectors? Do you have an aftermarket (standalone) ECU? If you're using the stock ECU, those injectors are FLOODING your engine and the stock ECU has no way of adjusting their pulse width for the increased flow that they have over stock injectors.
  21. They are disconnected (wiring connectors pulled OFF) but leaking?? Normally they would be stuck closed. An injector has a "pin" that is normally forced closed by a spring and fuel pressure (when there is fuel pressure). It has an electromagnet that opens it very quickly and briefly but should be always closed tightly otherwise. They also normally have a filter to keep debris large enough to cause problems OUT of the pintle area. I would have to think long and hard before I left those injectors in my car... (You can work them as stated above - even a 9V battery will make them open. Make them "c
