My uncle is unloading his 01' mr-s, and he offered it to me for 3k under bluebook. I've always wanted to build up a miata, but this seems like a good alternative considering the price. Has anybody out there dealt with one of these or have any words of wisdom when it comes to building one up for auto-x/road course duties? I really know nothing on these. All I know is that they are mid engined and have the crappy 140hp version of the celica's engine. I wonder if the high compression 180hp is interchangable?
