    1970 Porsche 911 with MFI, Hagerstown, MD

    5608195428_8453e16f5d_z.jpg

    The previous owner took a long hood, no sunroof 1970 911T coupe and built a German hot rod. It was his daily driver and also a weekend racer. He owned it for something like 25 years.

    What the PO told me:
    Engine and MFI came from a 1972 911T (2.4) but was rebuilt with larger P&Cs.
    (I think they are nickies, as the original T cylinders were cast iron.)
    I think the heads are S heads, but not 100% sure.
    All typical case machining was done.
    Also re-engineered the MFI pump to handle additional fuel requirements. (He was quite proud of that.)
    Displacement is now 2.7 litres using the 2.4 engine case.
    There is an external oil cooler in the right front wheel well (homebrew setup).
    Carrera tensioners were fitted.

    Transmission is a 915 from a 911SC. It has an electronic speedometer (odometer does not work). Reverse lights aren't hooked up, but I think I have the parts for this. Grinds a bit going into first at a stop light; I work around it by shifting into 2nd and then into 1st. Not sure whether this is a clutch issue or a transmission issue. Brand new clutch cable, installed last year.

    Brakes are 911S calipers up front, not sure what the rear brakes are. Master cylinder is a Mercedes unit that is larger than the stock Porsche part. The car stops as well as it goes.

    Body is a great 10 foot car. There are a few dings here and there. Rust under rear buckets was fixed by a body man fabricating replacements in his shop, since the rear buckets were not yet available in reproduction. Other rust in a few spots on the pan, but overall the body is solid and it has lived indoors the entire time I have owned it. The front bumper is fiberglass, as is the rear ducktail lid.

    I have replaced the headlight $witch since I owned the car, but it really should be rewired to use relays to kick the headlights on. Aftermarket radio blows fuses if you try to crank it. I think the engine sounds better anyway.

    The 15 inch Fuchs are presentable, but not as nice looking as they could be. Brand new tires installed just before Hershey.

    The car is a bit balky on cold starts, but once warmed up, the engine revs freely and will give you a rush above 4000 rpm. 185 rwhp, 170 ft-lb (per Dynojet @ Carlisle). It steers tight and brakes hard. Probably the best handling car I've ever owned; very responsive, like a grown up go-kart.

    I will include lots of extra parts, including the underdash A/C (removed for knee room), racing wheels/rubber (supposedly still have a few heat cycles left, but they are old), interior parts, engine parts, extra light fiberglass front bumper, even a set of brackets to mount through-the-grill fog/driving lights.

    Why am I selling this car? I don't drive it that much any more. I bought a motorcycle last year and I am enjoying it a lot more. I also don't have much time to work on it. I think it should go to someone who will drive it, race it, or restore it. Or all three.

    It will drive a whole lot better during warm up if you put the mfi pump enricher thermostat back on.

    Thanks for the heads-up. The PO built the motor and didn't include that part.
