If you have a us model 1980-83 911 SC and are looking to replace your heat exchangers we have some good and bad news. The original heat exchangers (part # 930 211 025 02) are no longer available from Porsche. But, these stainless-steel industries (ssi) heat exchangers will work with modifications. The good news is, once done, you will have more torque and horsepower! Free flow conversion heat exchangers improve sound and performance, while reducing backpressure and thermal load on the motor. These are based off the early style exhausts found on the 1974 2.7 l rs. Those models had a straight through, superior, free flow exhaust design that included a dual inlet muffler. When converting to these heat exchangers you will require: 2 inlet muffler (you can also choose a dual outlet or keep the stock single outlet) the FVD free flow oil line conversion kit, part # FVD211328anb. Conversion heater tubing please contact us directly to discuss your options so that we can put a kit together for you. Please note: this will only fit 911 SC us models from 1980-83. There is an o2 sensor bung on the left side heat exchanger, see the pictures and it is highlighted with the red arrow.
