sorry i didnt get back sooner, we have a huge time difference. i used the 81-84 22r-e (celicas in usa) reason being, it is a real basic computer it dosent have a fuel cut or rev limiter. and that is good with the 18r-g's, they rev alot higher than the 22r. the 81-84 22r-e is a 2 plug computer(instead of 3) and dosent have a knock senser. just extend the water temp. gauge wire and thats it. the 22r throttle boby will even bolt to the 18r-g manifold, use 4a-ge blue top injectors, and lean the 22r afm and it will run real good.
