I just fitted a one piece dump and front pipe to my car, tho I couldn't do one of the bolts up tight enough. So I have all bolts except one done up tight.

I'm not sure if there's a leak, but if there is will it affect performance?

Someone told me it won't, as it's after the turbo, but is this true?

probably not recommended for there to be leaks .. i mean i got one in my exhaust somewhere and i'm too lazy to do anything about it .. but what happens is that i rev up just fine .. no problems there .. but when u let go it doesn't go down smoothly which i guess i dont' just like .. theres a small splutter sound ... doesn't sound too nice to me ... and the rev needle bounces up and down slightly ... so yeah i'd make sure theres no leaks ...

no. O2 sensor wont be affect. Leak wouldnt be helping your exhuast system hold back pressure. Theres no advantages in having the POSSIBLE leak there so i would try n tighten that bolt up and if its in a pig of a place then get some bendy bits n pieces for your ratchet or what have u.

Yeah I had the same trouble, one bolt very had to get to, if you do the other ones up as tight as possible and the hard one fairly tight it shouldn't leak, get someone to heat up a spanner with an oxy and give it a bend, it helps.

      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).
