i vaguely remember someone posting a few PDF's in regards to mods before.. and i cant find them on here, or on the DPI website.

i'm basically interested in the engine conversion part of it, and going from a RB20 to a 25.

isn't it 20% increase in power/weight? not actual capacity? at least that's what i interpreted from that document.

unfortunately i'm going from a red top rb20 as well, so the starting figure is even lower... 180hp to *cough* 250hp...

The document says a few different things about power increase such as the part that states the maximum power the chasis come with... there is a few ways to interpurate as in all governement documents so it depends on the person or if you have an engineer then depends on them. Just read really careful and know your stuff so no one can bluff you :blush:

Hey man i work with DPI and licensing cars and all that stuff. You only need to have the vehicle inspected if there is a considerable power increase from the engine (i cant tell you percentage wise coz i dont know), or if the new engine has more/less cylinders.

We do have forms we can send out called change of engine number forms....ill check our website BRB

aha here we go, change of engine number form http://www.dpi.wa.gov.au/mediaFiles/lic_MR6_ChgEngNum.pdf

      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).

      Second time Skyline owner (R33 GTS-T and now a V36 370GT)

      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).
