Sorry, but you have a gen3 celica. 1970-1977 = gen1, 1978-1981 = gen2, 1982-1985 = gen3...
Yea thats true. Hmmm Well I think ill just go turbo thenIt wouldn't be worth it to convert your current engine. It would cost just a bit more to swap in a complete FI engine. If you convert, you'll need the intake manifold, injectors, fuel rail, cylinder head, fuel pump, fuel pressure regulator, FI computer, TPS, throttle body, and alot of other little parts, and sensors that I can't think of right now.
