This was the car that started it all for us. A 1983 Porsche 944 was traded for this 1980 Porsche 928 in the spring of 2004. This particular car started life as a humble 1980 928 with the US spec 4.5 liter engine with a 3-Speed automatic transmission. A previous cosmetic restoration had been completed on the vehicle including the addition of the burgundy interior from a later model S4. The turbocharging system consisted of:
Two KKK K26-6 units from the Audi AAN engine
Stainless steel log manifolds
Twin Tial 38mm remote wastegates
A large front mount intercooler
mass airflow conversion system with larger fuel injectors
The engine was torn down completely and the engine block was Nikasil plated and JE 2618 forged pistons were installed.
A true wolf in sheeps clothing, this car (while certainly not the most powerful car we've ever built) was a very fun ride, specifically considering the car would shift out of 1st gear just before 60 MPH. 0-60 times were clocked in the low 5 second range, while the 1/4 mile was measured at the mid 13 second mark at 106 MPH. These figures are quite impressive considering the base vehicle is lucky to manage 8 seconds / 16 seconds respectively.
The car was completed across a 6 week period in preparation for a show in 2004 and was driven to and from the show a total of 1,500+ miles. Power output on 10 psig was around 375 flywheel HP with about 420 ft-lbs of torque.
