the reason i push these guys are the engines are quality.
those long blocks at the bottom of the page are pretty much what you are looking for, though i'd seriously suggest upgrading to a B-series motor (b16,b18,b20) because the motors and transmissions have more aftermarket support and give a hell of a performance boost to boot.
