Looking at those pictures of the Toyota motor... it blows me away how much power they get out of such a tiny package. Especially considering that the motor is a structural part of the car that attaches the back half of the car to the front half! A ton of that motor's bulk has to be just to keep it from flexing during cornering.
I wonder if you could get your hands on one of those motors and drop it into a Hachi, or a 1st generation Celica/Supra, or a 1st generation MR2.

I'd love to see the look on someone's face if you fired up your mid-80's Toyota and it started doing an F1 style warmup rev program.
