The 72 and early 73 engines were MFI and 7.5:1. This is the 73.5 motor with "NEW" CIS injection. The factory bumped them to 8:1.

High power output is not the project goal for this car. 73.5 911Ts have become highly desireable as the last of the longhoods street drivers so I decided to leave the engine proper bone stock. The turbo hardware can be removed and with the addition of a couple of components return it to stock.

I have a take off 930 CAC but it won't fit without a whaletail and modification of the CIS manifold so CAC is a nogo. I believe chemical cooling has it's applications and it may go on.

It will have very distinctive turbine sound and mid range pull to augment the Porsche circa 1973 experience this car has.
