i am thinking of dropping the ralliart engine into my eclipse and was just wondering in any one new what the block the ralliart uses. Im guessing it is a 4g64 but not sure.

i think the ralliart engine is something like 4g93 or something but i'm pretty sure it's not 4g64.

its 4g92

Thanks,
Do you have any idea what the giffrence is as far as internals go. Cause I know that the 4g64 can hold 16 psi of boost stock.

dragon sorry about this but i just found out for sure it's 4g69 sorry about that

actually i'm not sure if it would hold 16 psi unless you go with changing internals your taking a chance if you go that high with blowing your engine it's better safe then sorry. i would build my engine internaly to take as much psi as i could than throwing a big ass turbo and finding out the hard way it can't.

the guy thast sells that turbo http://www.fiautosports.com/ has droped turbos on stock 4g64 with 120 miles boosting 11 psi with no problemes. He Now has 149,000 miles on it with no problemes. I am not planing on boosting more then eleven. But with this set up at 11 you get 300 at the wheels. Do you think that 4g69 will hold up the same.

i'm not really one to quote or be sure on that but alot of people go for less psi so there engine last longer, or will go longer before changing gaskets,and etc in there engine or turbo, so i may take it for a while and then go or not take it at all , but to be for sure find someone that has done it try roadracemotorsports or go on www.evolutionm.net (http://www.evolutionm.net) forum and find out from one of those guys. also don't forget the 4g69 is a new engine so there is hardly any of them that would have alot of miles or alot of miles with a turbo
