My 93 MR2 is an automatic, I would love to boost it but I hear that is pretty futile, unsound, and bad for the engine. I'm open to any options such as a swap to a standard tranny with a GTE turbo engine, or even the GTE with a triptronic tranny from "Level 10 Inc."

the easiest way to go would probably be the 3sgte swap or a v6.

I think the easiest thing to do would be to sell her and buy a Turbo or a 5 spd na...
Good luck/skill
