Anyone ever try converting the 1995-1996 year 6 speed porsche tranny's for mid engine use? For that matter, would it be easier if you were also installing the engine that was originally mated to that tranny, a 3.6?
Ideas, thoughts? Dino |

On the G50 (derived) gearboxes you can't flip the diff, so you'll have to mount the box upside down. Not really a problem, quite a few have done so...
But IIRC, the 6 speed gearboxes are too long to fit in a 914 |

But IIRC, the 6 speed gearboxes are too long to fit in a 914 The 5 speed G50 is already pretty long, so the 6 would be pushing it. I read somewhere that the G50 was actually initially designed to run inverted in a race car prior to being flipped over for production use. Either way, they seem to be very happy in a mid engine application. |

Another option I'm looking at is changing all of the gears so that the ratios are better matched for a higher torque engine. Dino |

Look up specs for the "Moby Dick" group 5 Martini car. They used a flipped trans to allow for MASSIVE wheels and a mid mounted engine in a 935 chassis. There were a few others in the same time period that did the same, but many of them turned out to have "diabloical" handling traits.
My idea: refab the rear suspension an elongate the body a little to accomodate the larger trans/engine combo. Best of luck. |
