Help,

I have just placed a 3.0 Euro motor in my '73 911e,

I currently do not have the correct rotor on the distrbutor, thus no rev limiter.

Does any one know the correct rotor OR a rotor with rev limiter that will work with this engine?

Any one with a Euro that can get me the part # of the rotor in their engine?

Thanks

Jon

Jon,

The euro 3.0L engines 78-83 used the same rotor, number 930.602.901.02.

Thanks,

Is this rotor the same as used in any other 911/930 available in the US?

The US and ROW rotors are different. The US cars do not have the rev limiter in the distributor, they have a fuel cutoff. If you put a US rotor in your ROW car, you will not have a rev limiter, in other words. I suppose that the change was to protect the catalytic converter from raw fuel when the rev limiter hits.

That is the problem I have right now.

I have an incorrect rotor on the dist. now. Thus I have no rev. limiter.

What is the difference in rotors, other than being rev limited or not?

Could I use a rev limited rotor from another year?

I don't know where in the USA to get a correct rotor. You might try dcAutomotive. At one time, he had some complete Euro 3.0 distributors. I should have bought one then, too. I don't know whether any of the turbo rotors might fit. That's the only other model with a similar distributor.

Call Kenn Young, who just moved to Reeves Porsche in Tampa (1-800-835-9256). He can order Porsche european parts for delivery here in the US.

I have ordered a US rotor for my 83SC, what are the down sides. Will I need to just monitor the tach and insure I don't redline, or is it a must have to avoid engine damage. Are other US parts taboo on Euro engines?

thks..seems I may be out a couple $$

You need the rev limiter, especially if you put on the SSI exhaust. With the exhaust backfit, the 3.0 big port motors will easily pull over 7,000 rpm if you're not vigilant. Not much of a problem on the street, but if you autocross or track the car, you will not always watch your rev limit carefully enough. I don't know for sure, but I don't want to learn the hard way whether Porsche made the SC valve train to run at those high speeds.

Swank911

From all the posts I have been reading the correct rotor for these engine has a limit of 6800 rpm +/-.

I will not be autocrossing next week unless I recieve the rotor.

Tom F

The rotor on my car is marked "6800." I suppose that this is the rev limit.

Swank911

Yes, at that speed the centrtifical force causes a contact to slide and break the electrical circuit thus stopping spark until the rpm is reduced.

Vertex has them.

Tom, if you have an euro ignition distributor, what is the bosch number written on the side of yours. I need to find out exactly what I have on mine. Also, if a fuel cutoff is present in the car, what controls it? The control box under the seat? Let me know.
