I have a frankentransmission made from a 911 and 901 side shifter. Basically it's a 911 (aka 901 with a pull clutch) with the side shift tail housing and shift rods installed. It's hooked to my 2.4 L MFI motor, and it works fine. It was built with the best of the parts from 3 transmissions, I only bought the gasket set for it. It shifts great!!!


If I were going to do it again, I would use the standard 914 clutch setup. The later 911 pull clutch is very heavy without the helper spring the 915 has.

I used this gearing.

1st. A (The standard first gear from a 914/4)
2nd. F ( The standard second gear from a 914/4)
3rd ZD Flipped (This is the fifth gear from a 914 /4 transmission)
4th S (This was the fourth gear from the 911 transmission)
5th HB Flipped (This was third gear from the 911 transmission)

This gives me a close ratio 4 speed with a really tall freeway gear. Sometimes I think its a bit too tall, the engine runs about 2200 rpm at 80 MPH.

If you are running 15 inch 50 series tires, the fifth I have would be great. I have 16 inch tires, and the rolling diameter is the same as the 165SR15 that came stock on a 914. So the gearing is just a bit too tall. I am thinking of pulling it and changing it to a ZD fifth (same as a 4 cylinder 914).

I hope that info helps.
