How's this? Dart block, eagle forged crank, rods and low compression pistons, main girdle reinforcement, venom injectors, edelbrock victor intake, and a custom turbo kit with a tune with about 20-25psi boost. But that's just my guess to even get close but 700hp I wouldn't count on.
its very possible to get more than 700 whp i have a mag upstairs with a 96 hatch having 792whp but only used on the track though...also fullrace has a 5 gen coupe putting over 700whp and also theres a prelude pushing over 700whp also i couldnt believe it my self when i read about them..
You gave us very vague description of what you really want in a car. If you want a race car, you gotta have money, lots of them, and do it right! I'm sure a lot of the members here know jgenginedynamics. I havent seen a lot of talk about them here, but I'm actually thinking of going with them. Hopefully, I will get some money when I get back from deployment. So, to the members who know or heard of jgenginedynamics, please post your opinion or advice.
my boy has a 650 whp si...its got a gsr block stroked with a type r head...completely buitl but has like 30g's init.Be realistic, i would reach a goal of an ET on the track and not hp.Cuz if ur ASKING people,online out of all places how to build a 700 whp 4 banger u r definetly not serious.but good luck!
