i have an 84 celica convertible with a 22-re motor. it's not very powerful, though, and i want to give it some more power without spending 5 or 6 grand on lc engineering parts. i've heard that an 83-84 supra motor will not fit in the engine bay. But with modifications to the firewall, motor/trans mount, driveshaft, and maybe something else, is it possible to drop a 7mge (preferably with, but possibly without a turbo) into an 84 celica? if so, how much of a horsepower increase would there be stock? and are there any good companies that make performance parts?
