The engine in the Turbo TransAms from 1989, were Buick 3.8 turbos. No "Pontiac heads". The build was so small, Pontiac would have never done a specific head. Not only would the head have cost a fortune but Pontiac would also have had to certify the engine with the EPA. It made much more sense to use the engine right from Buick.

Either way, that was a bad-*ssed car for 1989. I remember road testing a couple of them for magazines back then.
