The carborated (sp?) engine is called the 4A-C. (I think, I just got into Toyotas)

The supercharged motor you speak of is called the 4A-GZE and I believe it will bolt in, also he may want to look into the 4A-GE 20v, which is a variant of the original 4A-GE but with 5 valves per cylinder and individual throttle bodies among other things. It's what I dream about putting in my pos.
