I sure have. If you go to wolfpackradicals.com he has motor mounts for a .21 engine in a small block car.

his website is hard to understand with all of these numbers and stuff. Do you know if the mounts is all i need to put the motor in and run it? does the .21 motor match perfectly with the transmition i have on it ( stock rs4 trans )?

Thats all you should need.

If its the belt car itll handle the power. but if its the shaft one get hardened gears for the diff.
