We have done several engine swaps over the years, putting 964, 993, 930, 3.0SC and 3.2l engines in earlier cars. This used to make a lot of sense, but as the value of these early cars has gone up it must be considered carefully. There have been several of these :"outlaw" or gruppe R cars that have brought as much or more than original cars, but they have to be done properly. In this case we had 2 912s that had already been converted to flat 6 power, so we were not cutting up pristine early cars. Most of the modifications can be undone without any evidence they every happened. The main point of these conversions is a nice original early car is nice but a lightweight early car with a 300 HP 3.6l engine is lots and lots of fun. These cars have 911 engine mounts welded in, a 911 oil tank, 3.2l 911 oil cooling systems, custom made fuel and oil lines, correctly wired 964 ECUs and rebuilt 915 transmissions. We are using the stock exhaust on 1 and a custom exhaust on the other. Stay tuned as we progress on these cars.
