I have a 2004 pontiac grand am with a 2.2L ecotec automatic trans. Huge 2.4L intake manifold FULL 2.25 exhaust pacesetter headers high flow cat. Ported and polished 57mmto657mm throttle body and weaponsR intake filter. Im about to get installed a new transmission with a lsD and new torque converter with a 2500stall. Im planning on going turbo soon and install a SaaB9-3 turbo and i would like to kno if a Lsj crank or SaaB9-3 crank will fit my engine? Or which crank should I go with?
