Having co-joined my 73.5 911T CIS with its original engine, I would like to sell the non original engine with less than 20K since rebuild. The only history I have is that it was sourced from a Porsche engine rebuilding shop in Arizona on or about 1993--1995 and shipped to Switzerland where I purchased the car with both engines. The engine is complete and in good order. It would be nice to link it to the source vehicle. Asking $17,000.
