Posted: Thu Aug 11, 2011 12:53 am Post subject: Distributor Changes throughout the years |
|
|
Hello All, does anyone know if the distributors on 924 NA's ever changed throughout the years? Would one from a 1977 work on an 82 car? If not please provide me with some feedback.
Thanks,
John C

The distributors definitely changed...the early ones were points based. Then I believe there were the intermediate years, like 78-80; and then the late years like 81-onward. There are different part numbers listed in PET (although I don't have my copy with me at the moment to confirm the years and breakdown). The unfortunate things is that identifying what's what is very difficult because PET only lists the Porsche part numbers, which are not imprinted or stamped on the actual parts...the distributors themselves only contain the Bosch part numbers, and I've never been able to find or build a complete cross reference of Porsche-to-Bosch numbering (which would be very useful).
Also, I believe US and ROW spec dizzies are different, mainly due to the different ignition curves that would have been required.
So the short answer is, you need to find the correct distributor from a 1981-1982 US Spec 924 NA. _________________ erstwhile owner of just about every 924 variant ever made |

I thought I had read somewhere that they went through a few changes. Any idea where I might find one? New or Used?
Thanks,
John |

On my 82 924 NA, I have tried four different distributors and had issues with each. This included one that I bought online supposedly rebuilt, through a vendor that I am not doing business with again. Best thing I found was look up the part in the PET and get the right one rebuilt through a reputable business. The one I am driving on now was done locally by a reputable Bosche mechanic and has no issues. So now any troubleshooting on mine is done through this forum or by a Bosche mechanic only. _________________ 1982 Porsche N/A |

| Have any of the refurbishers/rebuilders ever explained which internal component(s) causes the problem? Is it the hall-effect sensor? |

With the distributor I brought to them the connector of the Hall Effect was not seating correctly in the side. The rubber gasket was worn. This was pointed out, and they suggested a complete rebuild with proper testing. I did not go any farther into detail on this. At the time I was frustrated with a non working car, with four dizzies, 2 ignition modules, three WURS, 3 sets of spark plug wires,etc., and no fuel delivery. Another member of the board and I believe that the distributor was not transmitting a decent signal for the fuel pump and was working with a spark that was there then not.
It was overdue in finding out what was bad and not. It turned out to be the distributor.
I got the car non working, and it had a distributor, in the engine, two in the back seat, and I got a rebuilt one from a vender. The one from a vender was rebuilt in California and looked like it was done in a low quality backyard business. _________________ 1982 Porsche N/A |

I am out of places to look for an ignition distributor (new or used) for my 82 924 NA.
If anyone has any suggestions, I would greatly appreciate the assistance. The Bosch Part # is 0 237 022 013.
Thanks,
John C |

I found a Bosch rebuild kit with a new hall effect sensor so I'm going to see if that solves my problem.
Thanks for all the assistance, I'll let you know how i make out. These distributors seem to be scarce compared to the earlier models (77-80).

Yes, pretty scarce just based on only two years of production and relatively few vehicles produced during that time frame;
Would you be kind enough to share the source of the rebuild kit??? _________________ erstwhile owner of just about every 924 variant ever made |

It appears to be the right one. The 82 924 base model has a three prong Hall effect sensor, unlike other years. They have two. _________________ 1982 Porsche N/A |
