Correct Distributor for my 2.4 T-V

[Swallowtail]

Hey everybody,

My car (Euro ’73 911 T-V) came with the pictured distributor in combination with a first gen. Permatune and some Bosch Coil.

First I’d like to know if this is the correct or at least suitable distributor for my car. My research leads me to believe it belongs to a 2.7 but I’m not sure.

My second question is in regards to the Pertronix insert. Is this regarded as a “good” solution and is it the correct unit for my car?

I’m considering replacing everything with a new 123ignition kit (electronic distributor, coil, cables and CDI replacement). Unfortunately that will set me back at least 1200 Euros.

The car ran with this setup but I have only driven it on and off a trailer, since I bought is as a project.

Thanks for the input but I even mentioned 123 in my original post. My main question is if it makes sense to try whats there or if it's a waste of time (and money - wires, finger, cap).

I agree that the distributor is from a 2.7, most likely not optimal for your engine.

I have used a Pertronix unit for years in my 73.5 CIS, works better that points for me.

Currently I am running a 3.0 with just a 123 unit, no HKZ CDI. Runs like a dream. I will add the Big-Fat-Spark unit soon.

A new distributor will always be better than a 50 year old unit?

The only difference between a 2.7 distributor and what was originally in your 2.4 car is the timing advance curve. You can look those up online or somewhere in this forum. Either one will work, but may not work optimally. Also remember that the engines from 1973-on had to comply with increasing emissions regulations, so none of them will be optimal. To get that, you will need to have the distributor springs modified, or go with an electronic setup, like the 123.

However, I would not mess with new components until you make sure everything works correctly with what you have. You know it runs, so remember the first rule of racing: "If it ain't broken, don't fix it." Get some time driving the car BEFORE you make any changes!

I like the Pertronix units. I have installed them on several old cars to replace points and condenser setup (a handful of VWs, a Corvair, several Studebakers, and my 1953 Hudson Hornet). It delivers a better spark, more accurate timing, and you don't have to readjust the timing. If the one on your car works, then it almost certainly is the correct one. You can check the Pertonix web site to see what part number works on your car. I'll bet that the Pertronix unit is the same for all early Porsches, and probably the same as VWs from the same time.

Thank you both! I did some more research and now believe that the 0231184001 is correct for both the 2.4 and 2.7 with 3-pin CDI.

I will give the current setup a try!

The correct distributor for 2.4 T-Vergaser (Euro) is Bosch 0231169008 / JFUD8
