I own a 2001 rs2.5.. I'm looking to make it as fast as possible to keep street legal iv looked into an allmotor build with ITB setup I'm just not sure if this is even a good idea on a subaru. I know turbo would definetly build me some power but just trying to stay away from the turbo. My question is which setup would be better of course turbo could build more power buuut could an all motor build with ITB setup create the same speed with less horsepower. I'm looking to go with a cosworth 2.6 strokerkit and basically anything extra to make it fast just don't know what? And another question let's say I make around 550 horsepower I don't want to be having to rebuild my transmission and rear end every other week what kinda idea can someone give me?? PLEASE HELP!
