Oop's, my bad.

Posted without spotting that there was a second page and the backpressure issue had already been addressed.

I was thiniking along the lines that if the turbo is working against a stupid amont of backpressure then to generate boost it will first have to overcome that issue. Then to generate positive pressure over that then you are essecially haveing to spin the turbo a lot faster than normal to generate say 12psi. As the turbo has to work harder to make that pressure then the wastegate needs to be held shut for longer which the weaker spring is unable to do. And so the EBC is working it's arse off.

There'd also be spooling issues that have been ruled out also.

To me a stronger spring/ higher preload is just masking the underlying problem and will eventually lead to a much bigger problem. Unless the original springs aren't quite what they're being sold as?

Actually, what i've just written is pointing more towards a restriction between the intake manifold and the turbo, not backpressure at all. hmmmm.

From the turbo into a huge intercooler 2.5inch or close out of the intercooler into a Q45 (80mm) throttle body mated straight up to a greddy plenum. Hope there is no restriction. Keep the ideas coming.

i think i will be going hi flow on my 33 gtst. Seems too good for what im after at the moment. Im not after big power, i gotta run my motor in for aslong as i can so a smaller more driveable turbo would be nice but one that also has abit of punch when needed. Seriously considering.

      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).
