Well...the 2T-GEU is N/A whilte the 3T-GTE is Turbo, so thats going to make a huge difference. Having driven a car with a 2T-GEU for the last 10 months, I have to say that they are quick, but not speed demons(without work). A good engine, but of course the 3T-GTE is going to be heaps and heaps faster.
