Got my car tuned but its going back soon.

Anyway its an R33 GTST Series 2 with the following:

Unopened RB25DET

HyperGear ATR43SS-2

3" JJR Bellmouth dump

HKS Hi Power Silent exhaust

Yellow jacket coils

NGK Copper plugs BCP7RES gapped to .7

Genuine HDI FMIC

Venom 5" body 100cpsi cat

Nismo 740cc injectors

Bosch 040(was failing during tune)

Nismo FPR

Greddy profec b spec 2

3" metal intake with Apexi power intake filter

Power FC tuned by Advan performance

Made 244rwkw on 11.4psi. That is with the boost controller set to 100%. That is as much as we can get out of it. With about 15psi, we should see about 270rwkw and 17psi about 280rwkw. 20psi should see 300rwkw on regular fuel pump.

Ive fitted a GTR fuel pump in there to fix the fuel pump issues. Probably will swap that with a brand new 040 pump or run it as a lift into a surge tank. Last printed dyno shows about 238rwkw on 11psi, should have printed the previous runs :P

Got it retuned, the AFR is perfect. Running more boost 15 low 19 high. Oddly enough high boost is seeing 250rwkw low boost is on about 217rwkw but low boost feels much stronger than the original 244rwkw on 11psi... Mind boggling. Intake pipe might be a huge restriction. Making close to 700nm of torque, it absolutely rips my face off compared to what it was before. Very impressed with the thorough tuning work done by Jez and bordy. A dyno gives you a number, but what you feel on the road is what counts and wow this is amazing. Just driving home on low boost the lift on the front end was intense.

      Hey Kaz, Unfortunately I am not at home currently and wont be for a few more months so I do not have access to my files or CAD. And at this point I prefer to keep the files to myself as I want to potentially make a few more pairs and see if they will sell within the EU before openly marketing them. But the way it's shaped and how small it is, I don't think you can fit both an indicator and a fog light onto the same surround, unless they were very small LED-type clusters.

      Replacement clutch recommendation for an R32 GTR

      By Ryno · Posted

      I’ve just installed a Uniclutch sport into my R32. I’ve been blown away by it… it drives like a stock Toyota Corolla. It doesn’t make sense to me that a performance clutch can drive this well. I was about to pull the trigger on a Nismo Coppermix twin plate when I discovered the Uniclutch and decided to give that a shot instead. They’ve changed the game and I couldn’t be happier.    I was previously using an Extreme cushioned button clutch with lightened flywheel. I’m still using the same lightened flywheel with the Uniclutch.
