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.

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).

      Might import a stagea

      By iamhe77 · Posted

      Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      Neil's R33 Gts-t Build

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
