Hey how's it going I'm building my gtr for a everyday driver/weekend track car mods so far are ...

Wiseco 87.5 forgies

Manley rods

Hardened and full balanced crank

Nitto pump

Ross harmonic

Exedy twin plate

Head work ...

Supertech 1mm valves both sides

Supertech guides

Supertech double springs

Tomei lifters

Now I'm in need of advice on personal experience with a strong street/track/drag 32 gtr with lift and duration of cams as I'm chasing 600+ hp with as much torque and best drivability I can get with a gt42r turbo any insight would be great thanks in advance

260 x 10.8 i think would be your best bet, they will have the air flow requiered to turn that turbo and enough over lap to give "midrange torque", what rear housing are you using, i have a mate with one of them on a 2JZ with a .86 and it doesn't see boost till 4500rpm on a 3ltr, on 15psi it makes 430rwhp (run in set up )

^ Indeed not going to be responsive for circuit with a GT42 in a 2.6ltr.

Be fine for drags though.

Sorta can't really have both with a turbo that large so might as well bite the bullet and just set it up for drags specifically and put bigger cams etc as you realistically can't set it up for both and then as a result there is dual compromise rather than one.

Thanks a million for the insight sorry on the delay in response lost passwords....

I have seen the light on the setup as i have a 400hp r33 as well with a gt35r and thats laggy enough for my liking but fun when on boost

I have been reading through the forums and the stock cams seem to be pretty popular ? Im going to turbo down with a to4z .96 rear bb garret or go back to twin n1 garrets ...

Thanks in advance

      I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?

      This came quicker than I thought. It ain't even 2025 yet.

      I somehow quoted my post instead of editing it. I regret nothing.
