What's the standard 911t distributor rotor like?

Post by RobFrost »

I bought this rev limiting rotor whi h says 69-77 911s. But it doesn't fit. The one in the car has a wider plastic top with two screws holding it on and two centrifugal weights immediately below the rotor. Which rotor is for which car?Image

I'm looking for a pre-impact bumper 911S or other high-revving 911 to restore - please let me know if you see one.

Is it a Bosch distributor or a Marelli?

Exactly.
The unit pictured is a Bosch arm.

The rotor arm in the Marelli distributor is held in place by 2 screws ...

Yes, I bought a Bosch arm for a Marelli distributor. Are they available for Marelli? I've had a look and can't find one.

New Marelli distributor caps & rotors were impossible to find for many years which is one of the main reasons why many/most people replaced the distributors with the equivalent Bosch version for their model.

More recently the caps & rotors have been made available again but are expensive - typically ~ £75 for the rotor arm.

I don't know if their are any UK stockists but they are available from the like of Rose Passion in France.
