EJ22... Gets away from the HG issues on the EJ25.

ej22 = 300,000 miles no problems
ej25 = h/g's every few miles

Definitely EJ22. I'll be using one in my Cessna car and would consider nothing else unless cost was no object (then I'd probably make it an electric). One big reason I didn't buy a new Subaru was that the no longer sell the 2.2 (because the cars are too f'n heavy to be moved by them, which is a combination, a Siamese if you will, issue that I had).
