Porsche 911 1974-77
Porsche 911 2.7S 1974-1977

New Perma Tune GEN 6 unit.

Bespoke distributor for the 911 engine with CIS injection and other engines like the Porsche Turbo 930 that use the three pin ignition module (CDI) and CIS injection

3 pin CDI with CIS injection was used from 1974 - 1978 on the 911

The Perma-Tune distributor is an exact fit, replacement part that will drop right into the engine. Setting the static timing is easy with the built in trigger point LED that lets you know when the rotor is pointing in the right direction. Idle timing is set in exactly the same way as the factory manual indicates and the factory mechanical and vacuum curves are preprogrammed into the distributor.
The mechanical vacuum can is replaced with a reliable MAP sensor that is fully programmable to perform advance, retard, vacuum and boost functions. On Turbo cars the vacuum/boost timing control can is very prone to leaks and the vacuum switches and manifold boost valves connected to the can are failure prone as well.
When these parts fail, performance deteriorates and fuel is wasted. These parts are bypassed by connecting the manifold hose directly to the MAP sensor of the distributor. It just doesn't get any easier than this.

The distributor harness is made using the same vinyl sleeve loom construction as the original wiring for that factory original look. It is very common on the Porsche 911 cars to develop engine misfire problems due to the brittle and deteriorating green shielded wire between the ignition distributor and module.
The defective wiring is replaced at the same time the new distributor is installed which cures two ills at once.

Distributors wear out and rob your engine of the horsepower it was intended to produce. Worse yet, they can leave you stranded or even damage the crankshaft ring gear.
Forget about rebuilding an outdated distributor with hard to find parts when you can replace it with modern technology that looks original. Replacing that worn out distributor has never been easier with the Perma-Tune distributor,
There are no wires to cut and splice: the distributor has the electrical harness built in and features the original equipment compatible connectors for a plug and play installation. Simply unplug the car harness connector from the ignition module and plug it into the matching connector of the distributor harness. Then plug the distributor harness connector into the Perma-Tune module and done.
There is no way to make a mistake with this installation, the connectors will only plug in the right way. The harness connector has built in diagnostics lights that tell you when the ignition system has power and when the ignition module is making sparks. The blue connector LED is a power indicator and the red connector LED is a strobe light that flashes each time the ignition system makes a spark, just like a timing light.
