hey, i currently have a redtop sr20 and planning on upgrading the valvetrain and fuel system, i hoping to get around 350 to 400 hp. the cars gonna be for circuit racing yes circuit not drifting so i need good midrange power and relatively quick spool up, i need to know a good turbo upgrade kit to get for it including fm intercooler. any suggestions??

 

Search much at all?

 

what..... is..... this..... search you keep talking about?

 

ya thanks for the help... i've searched allover but i dunno how good they are. i was looking at hks, apex, turbonetics, greddy, but i wunt to know how good these are, any experience with these?

 

Garrett GT2540R Turbocharger

also a big 28 upgrade might get you there as well..

 

what ar you runnin on yours?

 

s14 t28 ball bearing

 

are there any companies that make a t25 with all new manifolds fm intercooler downpipe blowoff valve and wastegate as a package?

 

you could get an s14 t28 bb and rebuild it, bore the exhasut housing a little i think thats what they do ive never done it lol. but it holds some more boost and its a t28 so youll have good spoolage=)

 

will the t28 fit right on ther or do i have to rearrange some stuff

 

The t28 fit right on stock manifold

 

cool, so i guess i'll buy a t28, then bore out the manifold and downpipe and buy a new wastegate and blowoff valve from hks, and an fm intercooler from greddy. sounds good right?

 

before you do that gt2817r is a very good choice to consider. it spools very nicely and can flow quite a bit. check out some flow maps and i think you'll like what you see.

 

yea either turbo would be nice, youll never reach 350+ hp on a stock t28 though....stock manifold bored or a tubular would work, for the turbo outlet just buy a 3in. dont bother boring the stock one, get the 3 in. downpipe with a flexpipe built in, and 3in. exhaust...grreat spoolage should then occur..also greddy just cam out with a mspec fmic thats pretty cheaply priced, get an hks wastegate

 

well all that sounds great except for the 3 inch exhausts. i dunno bout you but driving on the street wit a 3 inch gets to you after a while
