Doesn't the 3s-gte motor mount sideways in the car? Personally id look into a 7m-gte or a 2jzgte seeing as their both rwd engines, and you could mabey use their drivetrain. Mabey im wrong about the 3s-gte being mounted sideways....Mabey the MR-2 is diffrent than the Celica. IDK, damnit now im curious.
Anyways my friend did a 3s-gte swap into a 95 GT Celica in Deltona Florida. If you go to
www.ToyotaCelicaWeb.com on the forum you can do a search on it. That was basicly the main topic there for a while. The forum is no longer really active, but there is alot of good info there. BTW, I love 1st gen Celicas....id sell my soul to the devil for a decent one. Good luck, hope I helped.
I belive Titian Motorsports did a 85 Celica with a 7m-gte engine.
