I agree with the choices above. These engines are good runners and look good, too.
I have an October 1999 Copy of Street Rodder with a Fiat-powered lakester on the front cover. The engine, with the aluminum highly polished, is a real jewel!
The information provided above for the Mazda makes them look even more apealing. Parts availability might be better for the Mazdas, too.
Build one, shoot photos of every step you make, then publish it here! I'd love to see a project like that!
4-bangers, forever!
