Hey car was missfiring when under load more than 5 psi. After long thought i decided to do a wasted spark set up on it.

i use a rb25de ignitor from a 92 c33 (same as r32) and the loom aswell and a vn coil pack

From the s2 8 pin plug i wired up the 6 signals to the ignitor, it has a 3 pin plug but the black wire from the ignitor had no wire to go to after the plug so just cut it and grounded the ignitor,

The last 2 wires coming from the 8 pin plug (white & black) i joined to the 3 pin plug then the white to the 3 pins on the coil.

Last of all i conected the black one to 1&6 on the coil.

Started it up and it ran on 4 cylinders, 1 and 6 are not firing at all and 1&6 coil gets hot well the others stay cold.

please help i have looked round everywhere and can not find any information on it.

1&6 have never work at all

thanks

Thread dig, but I have the same problem with my S1.

Did you get it sorted? People have told me that I have blown my ignitor bridging wires 1/6, 2/5, 3/4....

Initially I didn't have 1 and 6 firing... but perhaps it was the pins I was using which clip into the bottom of the commodore series 2 (VR/VS/VT) coil packs. Now I have spark on all cylinders but just a Really Really rough idle.

Put the original setup back in there and now it won't even idle. Turns over coughs and farts but won't idle. Going to put wasted spark setup back in there and troubleshoot from there since it was running at least.

      Jacks that fit under GTR lips that can reach the subframe?

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
