1999 factory remanufactured 3.4L 996 engine. Engine was bought new from Porsche by previous owner of my car and only has appr. 50 hours of run time on it. Converted for 986 installation already so should make for an easy upgrade. X51 oil pan, otherwise stock. Runs great of course. Comes with power steering pump but no AC compressor or flywheel. Checked compression recently, all numbers were very good.
