'73 911E distributor part number? Bosch vs Porsche

[Gav P]

Hi all,

The distributor fitted to my 2.4E has the Bosch part number 0231 184 001. However, having done quite a bit of searching I think this may be the incorrect part. I have seen that it may be a 911T distributor corresponding to Porsche part number 911 602 021 CX. It also has "76" cast into the distributor body, suggesting to me that it is a replacement part fitted sometime after 1976...

My PET Porsche parts diagram has the 2.4E distributor listed as Porsche Part No. 911 602 027 01, which apparently may correspond to Bosch part number 0231 169 003 (can anyone verify this is correct?).

So, my question is, what are the differences between Bosch distributors 0231 184 001 and 0231 169 003? Are they effectively interchangeable, and should I keep the former and rebuild it (it's worn), or find a "169 003"?

Thanks,

[Gav P]

The Porsche technical Specs manual says jFUDR6 0231 169 004 for the 72 911E

Thanks. That lines up with the following info I've found - some replies over on DDK quoting Pelican posts (apologies to the original posters, I don't have your usernames) -

I'm missing some information but let me try. anyone who can fill in the blanks please do so. early distributors starting with the 2.4 carried the Bosch # 0 231 169 003 for the mfi T. ? on the E. 010 for the S, 011 for the RS and 008 for the CIS T.
The late #'s after 5/73 0 231 184 001 for the T, 002 for the E, 003 for the S and 004 for the RS. the primary difference is the direction the points face. On the early ones the points pivot is on the left, on the late distributor the points pivot on the right.

0.231.169.010 --> '73 911S

0.231.169.011 --> '73 RS 2.7


More from Pelican:

All 1972-3 2.4 distributors are identical in appearance, components and specs. Only reason for the different Bosch numbers is that they came with different rotors. The S rotor has a rev limit of 7300, E version 7100, and the T 6500 revs.

0231 169 008 is for the 2.4 911T
0231 169 009 is for the 2.4 911E
0231 169 010 is for the 2.4 911S

Same distributor came in a version with inverted points. These distributors have these Bosch numbers:

0231 169 003 for the 2.4 911T
0231 169 004 for the 2.4 911E
0231 169 005 for the 2.4 911S
End quote.

This goes some way to explaining the different part numbers then. I am guessing the same logic applies to the ~184 series too.

Bob - if you mean the rotor arm, then I don;t have the part number to hand. However, i have fitted the correct 7100 limiter type for the E (not pictured on the dizzy in this post though).

Cheers..

Hello Gev,

My 2.4E has the same 'wrong' distributor 0231184001. Have you replaced it with a 0231169009 and did it make a difference?

The non RPM rotor is actually a VW part although you consistantly see it on mid 70s distributor.

Hi Ed, based on the above info, I understand that the advance curve for the '184 001 is identical to that of the '169 - the '184 is just a later version which has the points pivot in a different location. The last part of the number simply denotes rotor arms with different rev limits for the various models. The '184 is therefore appropriate for the 911E if you fit the correct rev-limited rotor arm.

The one exception here is that I also understand the RS had a different advance curve to the T, E and S, so the above does not apply to the Carrera!

I had my '184 refurbished and the advance curve matches the factory spec for the 911E, as checked with the factory manual charts posted elsewhere on this forum.

I have obtained a '169 distributor, but it requires rebuild and I have not fitted it. By the time i had acquired it, I had already had my '184 refurbished and had bought petronix for the '184 which do not fit the flipped points of the '169...

In summary, a good '184 with the correct rotor arm should give identical performance to the other part-numbered dizzies mentioned above, if my understanding is correct

Hope that helps
