Was wondering if anyone has done this? I have been contemplating on doing this to my car.. i am sitting at 303 whp 270tq SAE on a dyno jet, but runing out of efficiency on my turbo... I gain squezze a few more HP, but would rather do it with a bigger turbo.. I like all my setup, so would like to keep it if possible... just wondering if anyone had ideas as far as maybe another turbo that will bolt up to it, or maybe another brand turbo and just get the manifold to mate to my exhaust? any ideas ?
thanks

 

what is your current setup, cause i was thinking about that in the future too

 

Your probably better off asking in the Forced Induction forum, i'm sure theres tons of gusy in there who, if you specify the current size and build of your current turbo, can tell you what you'll be able to upgrade to in its place.

 

Greddy turbo T517Z with all the goodies and methanol injection controlled through Hondata K-Pro@12 psi.

 

you're better off selling the greddy kit and building a custom setup.

the manifold for the greddy is not as free flowing as some of the other types you can buy.

wastegate -- tial will be a good choice.
turbo -- precision sc34 or sc61 depending on your car's usage.
larger injectors, stainless steel lines, cold plugs... etc will all be needed if you upgrade your turbo.
