do you realize how hard it would be to swap in a 3sgte. firewall has to be cut and moved. I had a mr2 spyder and sold it. Had it for about 2 1/2 years. I think i'm buying another one in a couple months. You don't buy these cars for power you buy them for their handling and it's incredibly hard to beat their handling. It was the funnest car I've ever driven, almost like a big go kart. Check out [ www.spyderchat.com ] quite a few people with turbo spyders.
