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.

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
