Well I'm buying a 2.5 block for my 04 wrx and I want to know how much power can I put down with my stock clutch, tranny, center diffs, and stock
turbo? What do i need to put 450whp in the future, what would I need then?

Thanks, Eric

 

you can get about 330whp on the stock clutch... the wrx trany is all in now now nice you are to it.. overr 350whp on a wrx trany and you really pushing it lol

 

U think it would be better just to buy a sti then do 450whp or
stick with the wrx and do the tran, clutch, ect?

 

I might buy an evo too.

From personal experience, avoid the Hybrid route.

 

These two posts go well together. Avoid what you were thinking, and either a) buy an STi for a bigger build, or b) buy an Evo (with the 5spd for ****'s sake), and mod it.

Judging by all the great results the Evo's have had with E85 tuning (including i-club's own ssteve), you'd be able to spend hardly anything, buying some fuel upgrades, headers, and exhaust, and with tuning you'll be making more than some bolt-on turbo STi's; all for less money to boot.

 

Why?

 

^hybrid herb strains are never to be avoided.

hybrid block-head pairings are to be scrutinized, because the engineering required is sometimes overlooked. Done right they can scream, done wrong they can ream.
