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.

Kurt Donohoe at Partsklassik is a good choice.

Hey Luke
Barry Hirshon rebuilt the S dizzy for my stock 6 engine.
I didn't know he has a company name, Distributor Lab
He did a good job.

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... idea.gif

I spoke to Barry today.
It was a difficult interaction.
Still gathering info.

I’m looking at FI and MS for my 3.0. Bitzracing.

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

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 dunno. But for my 1980 911sc it seemed like the MSD box made the most sense.

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.

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?

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.

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

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. blink.gif . Totally got me hooked 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.

No I should have done that. I saw a dyno chart for a similar 3.0L but with DC40 cams and larger 3.2 heads. It was making 260hp at the crank. I think I was in the 230hp range.

agree.gif I used PartsKlassic to rebuild/recurve the Bosh dizzy on my 2.4L w/PMO carbs.
priced reasonably and fast turnaround.

I switched to MSD when I did my /6 conversion - no regrets. Barry rebuilt/recurved mine - his price was higher but his technical knowledge seems far beyond the other guys. Is it worth it? Up to you.

Excellent.
I shouldn't be concerned about having the smaller intake ports ?
Carb specifics would be greatly appreciated
Your pistons were standard SC ?
Any head work ?
TIA

The smaller intake ports give better low end response. The dc19 is not a huge duration high hp cam, so I think it’s still a good match. How much hp is there to gain over a stock or 964 cam grind is hard to tell, dc racing might know bettter. I had stock 81 heads and stock pistons, motor long block was all stock 81 3.0 besides the cams.

The next level up would be larger head ports, dc40 cams and je pistons. But that’s a good chunk of change, should give another ~30hp. I would do that all at once, I don’t think head work willl matter too much without dc40 or larger cams, but I could be wrong. And to run those cams you need new pistons. One thing that is nice with dc40 cams they are designed for carbs ( I think better lobe center) so they react faster to the carbs.

I will dig up and send you my old carb settings.
