EFI Conversion for 74-83 911 models.

 

Above is a 1978 911SC California car with fully operational smog equipment. Original appearance has been maintained.

By converting your engine from CIS to Electronic Fuel Injection, you will bring your 74-83 911 up to today's standards. The improvement in drivability and performance will amaze you. This conversion eliminates all the surging & roughness of the CIS, and produces smoothness and performance you can compare to much newer Porsche models.

It uses many of the proven fuel system components of the 84-89 Porsche 911 Carrera.

The cost is much less than the replacement cost of your original CIS. Future enhancements can easily be accommodated by reprogramming. An increase of between 10 + 14hp can be expected with this upgrade.

The Control unit (ECU) is located in the passenger compartment and is accessed through a standard PC serial cable. Originally adapted to the 911 SC by Tony Bitzanis, this EFI conversion has been further enhanced by Auto Sport and maintains a factory original appearance by using the original German 911 EFI fuel hose with crimped ends. These are custom made for this application. New injectors are matched to the 911's exact engine requirements, and the ECU receives a final programming once installed in your specific vehicle.
