I own an srt-4 and i know that newer generation motors are able to handle a crap load of power out the box, im still guaging myself to guy an EVO; how much of engine buildup if any is required to do 450-600awhp?

 

Evo Motor=4g63

 

stock block can handle 500whp with the correct tune

 

It's about this strong:

 

^wtf!?

 

ARP head studs ($100)... that's all the build needed really... and the stock bottom will hold 500whp... that's the 4G63 by the way... not sure what the 4G68 will hold

 

Dave Buschur and many others are making 400 wheel HP and up on the stock head bolts. As long as the tune is correct and you don't have any detonation I see no reason more isn't possible on a bone stock motor. I have read about 550+ wheel HP on the stock block with ARP head studs and rod bolts.

jsut to let you know, this guy isn't actually strong at all. i read an article about him, and the only reason his biceps are that big is because he injects an oil, unknown what kind, into his arms. he barely curls 45 lb dumbbells. and by the way, he was also arrested at a gym for selling steroids... so that's a bad analogy of how strong the evo engine is...

 

wow i thought that picture was chopped, it looks really stupid cuz the rest of his body/forearms dont match his biceps in any way.

 

 

wow, talk about off topic now...lol


anyways..

here's the thing 4g63, I admit I'm really new to...always been a Toyota and Nissan guy. There are massive ppl who safely put 400 to500 hp to their 4g and I think that's safe. But I really do trust the 3S-GTE and SR20DET motors more than 4G but that's only b/c the Evo's my first 4G i've ever owned...so please don't flame..

 

4g63 > all

 

lol @ 4g68, but i bet that engine is strong

 

how about sti motor? they seem to hold big hp w/ no problem

 

They can hold about 350hp without a problem, anything larger than that causes the engine to die in various ways. The 4G63 is a much stronger engine, chalk it up to experience or whatever.
