Porsche 914 cableshifter DIY

My Cable shift kit for the Porsche 901 tail shift transmission

This is now a DO IT YOURSELF webpage!

Features: - A short throw shifter for quick shifting
- Stock side to side shifting motion to maintain resolution between gears
- A spring return to center for "2nd-3rd",
- Dead stops at "1st-Rev" and "4th-5th"
- Shift cables pass through the firewall via the existing shift rod hole, no cutting is required to install.
- Shifter mechanism securely mounts to the tail shifter using three nuts.
- Available cables are rated 310 degrees F. to withstand heat from the engine, and are sealed against weather.
    This was basically an experiement to determine the feasiblity of a cable shifted 901.
    Running problem free since July '02

The shifter is located in plane with the steering wheel, so its at a
comfortable distance and inches away from where your hand is on the wheel.

My design covers the stock heater control, this can be easily avoided
by mounting the shifter closer to the passenger seat. I needed the room for
my pipes. My heater valve is poking through the carpet.
