Hey guys i own a r32 gtr 93 model and im having issues with my car.

Il state the mods to help you guys with answers.

Full exhaust system 3 inch

Apexi pod filters

Nismo afm's

Sard 700 cc injectors

Bosch 040 pump

Hks 2530 turbos

Greddy boost controller 15 psi boost

Power fc ecu tuned

Splitfire coilpacks

Iriway 7 spark plugs

The coilpacks were purchased second hand of a member on the forum about 7 months ago, they were fine till the last couple of days as to my knowledge. Now as i drive normal everything is sweet but as soon as it gets past about 4000rpm it missfires then it drops a cylinder and sounds like a wrx. Im guessing its the coilpacks that are efffd, but my car isnt that heavily moded to fail a splitfire coilpack (280 kw at all fours).

Am i right to lean towards faulty coilpacks? Or is it not possible for them to die so easily?

Thanks in advance

Sorry don't know the exact name for it but could be the brain that the coil packs are all connected to as well? It kinda dies in the ass sometimes due to heat, but it quite possibly could be the packs themselves. Try another set.

The coils sound dead but try the resitor first it's the silver and black box that sits on top of the coil pack cover. I have coil packs and a resistor you can try to find out the problem I'm on the coast where in syd you live?

The "resistor" box is not a resistor. It's the ignitor. R32 (RB20 and RB26) and S1 R33 RB25 use the same igniter and coils. S2 RB25 coils are not compatible with the earlier ones.

Because all your ignition gear is relatively new, it would be strange (but possible) for something in there to have died. I'd also suspect that one of the injectors might have an issue, so if you get desperate get them tested too.

And then there's the CAS.

cheers

Turned out my ignitor was gone. No issues after replacing with another.

Cheers for the help guys!

Interesting. My brother-in-law was recently handballed a Legnum wagon that no-one else could make work. He worked out that the ignitor was stuffed......but a new one didn't help. Then they found that the ECU was torched. It had had coolant in it at some earlier stage when a heater hose had died. When the ECU went, it took out the ignitor. Sounds like you might have suffered something similar (ie, ECU killing the ignitor).

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
