I'm looking at buying a modified R33 GTS-T in the ACT. Just wondering if any of these mods need to be engineered:

  • Aftermarket top mount turbo manifold with GT35 Turbo
  • Aftermarket wastegate
  • Aftermarket intake manifold and throttle body
  • Front mount intercooler
  • Dual stage boost controller
  • 18" Wheels

Thanks! :)

LOL yep, what makes you think all of those wouldn't?

You'd need a noise test, emissions test, mesh in front of the intercooler, engineers inspection, and that boost controller wont be legal. Anything adjustable is not legal engine wise.

AFAIK turbo mods don't need to be engineered as engineers certificates are for ensuring safety for the car only. Just read it here: http://www.performan....php?t=67239791 -not sure if this is true or applicable to my state.

I know the boost controller wouldn't be legal as it means you can adjust the performance by more than 15%, although as long as it's hidden I doubt it would be a problem.

Why would you need mesh in front of the intercooler?

Emission and noise tests can be done anywhere and has got nothing to do with an engineers certificate???

Might differ from state to state, but of course emissions and noise tests are related to engineers certs. An engineer wont sign off on a car's mods unless it has a emissions report and a noise test done.

Don't know where you've read it, but you definitely need an engineers cert for an aftermarket turbo dude... You cant just wack a T51r on a skyline and expect it to be legal, you'l get pulled over and defected

You need mesh infront of the intercooler for a safety thing, dont ask, but it's a requirement in most states AFAIK.

p.s. post #5 of that link:

In the ACT and NSW you need an engineers cert for any non-OEM turbo setup.

Also Turbo transplants - ie Mazda BPT from the Laser into a 323 despite the chassis being the same etc.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
