Well the 4T-GTE was found in the Celica GT-TR's, and it's a 2 Litre engine. This is the road version of the Celica Rally Car.
From what I know, externally the engine is the same, you can only tell it apart by the plate on the front, with 4T-GTE written on it. I don;t know if the engine nuymber on the block starts from 3T or 4T, but I've heard a few people say that they came with 3T written on the block.
One thing for sure, is that the engines are very rare, and very good

Wouldn't mind getting one for a project car.
