hey all just looking at getting a new turbo for my r33, current mods are ase fmic, 500hp walbro fp, hks cat bak, pod filter, platnum plugs, running 11psi. I believe everything is stock but not sure as my last dyno i had my car got 221rwkw. Anyway im looking at these three options HKS 2530, HKS gtrs or just get mine highflowed, i am looking to get round 240-250rwkw's would like to kno which one would best suit my setup im after good response not a hell laggy turbo. If anyone could suggest a different turbo let me kno. My mate is goin to japan in just over a week so i may give him money to get me one as they would be alot cheaper over there cheers jarad
