Looking for anyone who has had good results with a distributor re-curve rebuild.
The engine is a stock 1981 911 SC converted to carbs Of course Jerry Woods is well known.....anyone else ? |

Hi Rory, There's a guy in Mich that does the re-curve too. I spoke with him last year about my brothers sc dizzy re-curve. IIRC price was about the same between him and Woods. https://distributorlab.com/ |

Kurt Donohoe at Partsklassik is a good choice.

I didn't know he has a company name, Distributor Lab He did a good job. Rory |

What's all this then? Group: Members Posts: 371 Joined: 26-May 04 From: Cheyenne, WY Member No.: 2,108 Region Association: Rocky Mountains |
In the process of this exact thing. I spoke with Barry Hershon yesterday and he quoted $1200 which included rebuilding, re-curving and removing/blocking off the vacuum advance/retard can and was insistent that I switch from the stock Bosch CDI to an MSD system for another $300.
Got an email from Aaron this morning. His price is $595 to rebuild, re-curve and block off the vacuum port. Also contacted Partsklassic and the guy in Utah (whose name isn't coming to me) and haven't heard back. Seems like there are fans of all of the places mentioned and a few detractors for some. Trying to decide if it's worth $600-$1200 to do this... (IMG:style_emoticons/default/idea.gif) |

For anywhere close to $1000, I'd look into going with a crankfire set up.

For anywhere close to $1000, I'd look into going with a crankfire set up. (IMG:style_emoticons/default/agree.gif) If a frugal DYI'er for about $500 you can do a megajolt/E using proven reliable Ford EDIS parts, or I believe you can run MS as ignition only, which would give you the option of FI in the future. Both have programmable curves and both could be adapted to a future twin plug. The trigger wheel isn't that hard to do, but for $190 ($220 with AC) goingsuperfast.com has a nice kit that includes pulley, trigger wheel, sensor mount and dizzy hole plug. About 3/4 way down the page. http://goingsuperfast.com/Porsche.html I used a Patrick twin plug dizzy, but only because I got a deal (practically steal) on the dizzy with wires. |

I used Rennsport Systems to re curve and then bought an msd 6al. Works great and was much less than costs quoted here. That was 2008, so I’m sure some pricing has gone up.
http://rennsportsystems.com Btw, re curving the dizzy was worth it, gave the motor a good snappy response. |

What about 123 Distributor along with the MSD unit? There is a group buy on them at:

The rebuild / replace is in my future too. Local expert quotes $600 or so for rebuild & recurve of my Bosch unit - but the 123 new gives me programmability and is markedly cheaper.
Anyone have hands-on experience withe the 123 unit on a 6? |

Anyone have hands-on experience withe the 123 unit on a 6? I bought one for my 914-6 with 2.2E engine but I haven't had time to put it in yet. I too looked at recurving my stock Bosch distributor but the advantages of the 123 Distributor look appealing to me. Hopefully I will get it installed in the next few weeks when the weather is better to be able to test it out. Jeff B |

A 356 friend has "B" hotrod with the 123 in it. Says he can tune it from his phone. Car runs well!

Looking for anyone who has had good results with a distributor re-curve rebuild. The engine is a stock 1981 911 SC converted to carbs Of course Jerry Woods is well known.....anyone else ? Btw, this motor is exactly what I started with. I ran it with DC19 cams, headers, re-curved dizzy and webber IDA 40's. I can probably find my old carb settings if you want. It was a phenomenal motor. I was at thunderhill with a stock '81 911 on slicks, I blew his doors off and lapped him with in the 20 minute run session. I know the 914 is lighter, but there was no comparison between cars. The 911 owner was stunned. (IMG:style_emoticons/default/blink.gif) . Totally got me hooked (IMG:style_emoticons/default/smile.gif). Also the DC19 cam can be run with stock FI pistons- http://www.drcamshafts.com/. I think it really helped the motor kick in along with the re-curved dizzy. |
