The 20R 2200cc. / 22R 2400cc. engines were the most popular US Toyota engines. For 20 years, 1975 to 1995, these motors served as U.S.Toyota's dependable workhorse engine. These engines powered the popular Celicas until 1985, and the unbreakable Pick-up models used these engines until 1995 (in commercial models). Turbo models appeared briefly as the 22RTE in 1985-1988 on Pick-up and 4Runners. The 22RE Fuel injection models appeared in 1983, on some Celica and Pick-up models. In 1985- the 22RE had a major change. The block was taller and the head shorter, compared to the earlier models. The engines' blocks and heads are not interchangeable (for practical and cost purpose).
Ask me about how to really make these run!, or better yet, using a 22rte with multiple turbo's. Wow!
Used to build these little guys for some sand rails before everyone got crazy and started using V8's.
