Hey Matt, you might try an 88-89 MR2 SC, since they gave them a supercharger, they just might have given them a different final drive gear. If not TRD or perhaps even Toysport might be able to help you out, Toysport has been very helpfull with my 87 Celica project. Also give Rick a call at Toyhead Auto Restoration, he as well as the others I've mentioned can all be found on the web.
