i am looking into this kit and i have a few questions for any of you that know about it or have it on your gsr's...what size turbo is it t3? and the emanage comes pretuned right? and at what psi does the kit come preset for and how much whp do you get from it? also, other than an intercooler, what would i need to get for it? i plan on running stock internals. any info you have would be great,,,i just wanna know if its worth it?

 

you should SEARCH. THis has been covered numerous times....
Make sure to click on "archived" when you search

 

Yes, search. But specifically, take a look in the Forced Induction forum. There is a FAQ at the top of it. There are links within it that give you lots of good information about the Greddy kit specifically, as well as pretty much any other kit available.
