hahaha japanese car with a V8 hahaha ive seen them but trhey were all done by people with the big enough bank to build it for the V8 set up, ive even seen a v12 in a supra body, it just took over 100K easy to do. but... Toyota supras can be both manual or automatic. wether its your 1jz motor or your 2jz motor. The BPU would be very nice as it has a twin turbo set up, singles are nice but the twin would just own.
