I found this dyno chart for a busa. I think it had an after market exhaust, but not to far from stock. You'll notice that at around 5500rpms it's sitting around the 85ft/lbs mark.

The 4age in my car makes peak torque slightly before 4700 rpm

Just to drive around town you'll be shifting near 5K or more....... This is an all around, not worth it idea. The busa engine also wont last as long in a car chassis, it wasnt designed with any of this in mind (pushing a 2200 lb. car everyday) So your adding stress that will shorten its life, hard to tell by how much. So if you intend to make a daily driver this is a terrible idea, if your making this a track car on the otherhand I may understand better.

Also, the previous owner told you he dropped 200 lbs. off... And you beleived him? Had he weighed the car, before and after he stripped whatever he did? Because otherwise he didnt have a clue. The butt dyno and the guesstimascale are about equally accurate. Do you have any idea how much come off of an MR2 to shave 200, much less 300 lbs? Please enlighten me as to everything you, and the previous owner have done to lighten your car. And also while you at the scales, if you go, take a picture of your car on the scale, and snap a pic of the weight you are given. That way if it indeed weighs around a ton even, you will have proof, I am still very skeptical.
