Acutally, these are your choices : BlueBird: AWD GTi-R: AWD Avenir: AWD There are NO FWD SR20DET's, they fit onto our tranny, but they did not come like that from factory. BlueBird is 205hp I beleive, cheapest one too. GTi-R: is 220 hp, quad throttle bodies, 444cc injectors, hardest swap. Avenir: recent engine, more expensive, 227hp I beleive, without the complications of the GTi-R engine. Chris
