May be possible to use R34 ecu if you are going to replace coils etc and you can get a whole loom and fit it while your engine is out... and Nistune that. Anyone done that?

Coils, CAS and injectors are different..

Might aswell just start with a Neo head..

well he already has a 25de in his car. so I thought that would be the best place to go from.. using that loom and head. cas etc

he has an R32 DE head without VCT? or R33 DE head with VCT?

if he has the R32 head, use the R32 loom and sensors etc and just retune the stock ECU.

Yep, using the head/wiring/sensor setup that already suits the car is the easist way to go but as TiTs said, need to use a Z32 ECU if he wants to Nistune and retain VCT.

its a 33 head with vct.. which he wants to keep. could he just use the z32 ecu and get it chipped or tuned or would he need to get a nistune? (I know thats not the only option, but thats all his budget allows for)

Also with using the z32 ecu, what are the wiring differences that need to be fixed up?

    • Well, yes, every CU on the bus is available via the Consult port, but whether the scanner you are using is capable of talking to the TCU, the ABS/TCS modules, etc etc, is what is at question here. Many of them are only for engine codes. So, if you have one of those, you won't know if the ABS is having a bitch.
    • That's now. R chassis Skylines come from a time when the tolerance in the ADRs was a bit more....slack. My car, on 235/35-17, which is damn near the exact same size as the original 205/55-16, is pretty much bang on correct indicated speed across the whole legal range. That's demonstrated with constant speed run over 5km, and GPS speed. It's just the luck of the draw. My particular speedo head has to be the thing that is "calibrated" that way, because everything else (the diff ratio, the gearbox and the speedo drive**) are all same same as most other Skylines. **OK, so the speedo drive is a Navara unit to drive the R32's cable, not the electronic unit than an R33/4 would normally have with teh same gear on it. Otherwise, I applaud your OCD tendencies, and I would do the same if I needed to.
    • Not too sure, I believe the Nissan consult port does everything? Also just filled up the reservoir to full and the light is still on. The float seems to move up and down fine.
    • The speedo's can be very conservative, when my Mazda NC MX5 speedo is showing 118kph, the GPS, and a calibrated radar.... cop mate.....hits me at around 110kph +/- 1 or 2 kph, and that is on a 215/45 17, stock tyres size is 205/45 17 as well, so weirdly conservative with stock tyre size When my Commodore speedo red 116kph GPS had me at 110kph on 255/40 17, so again conservative Google says manufacturers need to set the speedo from 4 to 10% slower than actual road speed.....for safety.....and compliance  After doing some offset and clearance measurements to see what can fit the NC on 17x8 +40, without guard rolling or rubbing anything at my current ride height, I've decided that when my tyres are toast, I'm going to fit 225/45 17 and see where that gets me IRT actual speed of my speedo and GPS/radar From the online calculator I should be still be doing around 5kph under an actual 110kph when the speedo is showing 110kph My ADHD requires that when I'm doing 110kph on the speedo, that the actual road speed is actually really close to that, and not alot slower And going from 205 to 225 still keeps the car within the %/mm allowable in the NSW vehicle rules and regulations, which is nice, as long as I'm looking at the latest version that is.....LOL https://www.nsw.gov.au/sites/default/files/2021-02/RMS-13.464-Light-vehicle-modifications-Vehicle-Standards-Information-No-6-November-2013.pdf
    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
