You could use a dremel it might make it easier in places. I just used 400 grit wet and dry then 800, then used a combination of polishing wheels finally finished off with autosol... came up ok... I'm not looking for ward to doing the plenum though... I did the cam covers the same way, came up mirror, but I'm now thinking I will paint them as having to maintain the shine of polished alloy is very time intensive...

sounds good, do you have pics of the end result? i think it might save quite a bit for coin which could be better spent on food ^_^

I don't have a decent camera but this is how the cam covers came out... it is really mirror like, they wern't too hard to do... just takes alot of time..

On the other hand the intake pipe and plenum take a lot more sanding to get it smooth but ends up the same, you do have to be careful to keep it smooth and not a wavy finish. When it is polished you will see distorted reflection. it would be easier to use a bench grinder with buff wheel attached..

I think I will just sand it smooth and paint all the polished bits a colour, maybe silver, as keeping the polished alloy nice and shiny takes time. My car is not a daily driver and it still needs a polish at least once a month to keep it looking great...

fo the cross over pipe, get something a bit more aggressive to get it smooth before you hit it with wet 400 - 400 would take along time to get rid of the casting marks.

go all the way through to 1200 or 2000 for final run

try not to sand in the one direction the whole time either.

check out other tips in the polishing post within the fabrication section.

      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).
