328 TT GTO Conversion

This engine was originally built by Carpenter. It was rebuilt by us and updated. The compression ratio was lowered to 8:1, F40 head gaskets replaced the copper ones (which leaked badly), the engine management was changed to Motec with electronic wastegate control and the fuel system up-rated. This engine ran a conservative 12 lbs. of boost; more power is there for the taking.
