    Smile FS: 1973 911T motor with matching 915 transaxle (SoCal, Aliso Viejo)

    For sale a 2,341cc flat-six and Type 915 five-speed manual transmission were removed from a 1973 Porsche 911T that was being modified with a 993 powertrain. The engine is mechanically fuel injected and retains ignition, oiling, exhaust, and intake systems. In December, the engine was inspected by Sleepers Speed Shop in Costa Mesa, California, where leak-down and compression tests were also performed. The engine is in my garage in Aliso Viejo, California.
    If you have any questions please let me know! I am
    Looking to get $20k for the complete running engine and transmission.

    My wife wants it out of the garage, so I’m a bit more motivated now. 🤦🏻*♂️

    Kami,
    Maybe I am not reading these numbers correctly, but the leak down numbers are awful. A freshly rebuilt engine will normally have 2-3% leak down numbers. A good engine should have all cylinders below 12% or so. 20% is borderline. Your #5 and #6 cylinders 55% and 63%! The motor is unusable as is, and likely needs a full rebuild. In view of this, your ask price of $20k is very unrealistic for an engine that will need another $10-15k thrown at it to make it usable. Just as a reality check, plug and play 2.2S and 2.4S motors with complete MFI set-up can be had for mid $20's...
