As stated have no injector pulse if car is driven till normal operating temp. After turning car off car will just crank, has great spark but no injector pulse. Cold start perfect, never cuts out once running.

Background info: r32 has just gone major heart transplant from rb20 to rb25/30 with highmount gt3082, front facing plenum, gtr injectors and resistor pack (which i have changed back to standard) + nistune. Absolutely hauls arse.... but pull into servo to fill up and have to wait 15mins or so before it will fire back into life.

I had the nistune board installed by electronic repair man who had never done this before which is where i believe the problem may lie. Has anyone had anything like this happen before???

Any feedback much appreciated, thanks in advance.

Checked with noid light on injector plug. Definately has fuel pressure. Has power to one side of the injectors. Has good spark on crank.

You really need to get data and check what your hot cranking on time is. To me it sounds software related - ie an incorrectly calibrated table. If you send me the bin image I can have a look for you.

sorry guys should have been clearer. WAS running gtr injectors with resistor pack, but thinking this was the problem i removed the resistor pack and re-installed standard injectors. I since have reverted back to stock as a rock rb20 tune and the hot start problem still remains. NO injector pulse at all, but good spark.

    • 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?
    • 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).
