no, the idea behind the swap in a motor and transmission that are extremely solid and well built, plus trying something that hasn't been done before. The most popular swaps these days with MR2s involve swapping a V6 on the later GenIII motors into them, but the motors themselves are VERY expensive and take a lot of reworking of the hubs and such. I've been very pleased with every M42 i've been in, and would like to just try something new.
