What’s special about this listing

1975 Porsche 911 DP935 Street
Andial 3.4L Engine / Close Ratio 915 / LSD
Clean Title - 56k Miles

Here is a rare opportunity to own an early DP Motorsport 935 street. This car started life in Germany as a euro-market Silver Anniversary Edition non-sunroof model and was converted by DP Motorsport at some point in the late 70’s / early 80’s (original paperwork not available). The car was imported to the US in 1984 and lived in Sarasota, FL for many years. We acquired the car from its 3rd US owner who had owned it since 1991. At some point in its life, the original 2.7L magnesium block engine gave out, as most of them did. A 3.0L case out of a 1978 911SC was sourced as a platform to build a monster naturally aspirated engine with old-school roots. Below are more details:

All in all, there is nothing quite comparable on the market and surely not at your local cars & coffee. The early DP935 street cars had a very unique look which, compared to the later DP935 II, consisted of a narrower body and swallow tail, or longtail. This car is very nimble, feels light on its feet and is seriously fast. The engine is estimated to make 300whp and it feels like every bit of it. Be sure to watch the driving videos to see what this car is all about. Just serviced with fresh oil, valve cover gaskets & tires making this DP935 turn-key and ready to be enjoyed.
