Into a 96 isn't that hard . I belive it uses the same mounts . The tranny may have issues with holding the power as I dont know about an MR2 Turbo tranny bolting right in with perfect use of the axles from the 2 .

Your looking at probally 1k for a good motor/tranny/harness . This is a 91 3S . A 93 or newer is going to run more because of the better tranny better port flow in the head .

For a full swap I would say look at 3K or maybe a little more . It has been done I know that . I have seen a 3S with 450FWHP in a Camry with a GT30 and FMIC , Standalone .
