Electronic Ignition

[Motorsen]

Hi all

I am the happy owner of a 1969 912.
Does anyone knows which type of Bosch distributor will fit my 912, if I want to have Electronic Ignition+

/Ole

[C. Clark]

Bosch.022, .031, non Bosch .009 (not recommended), .050 (marginal) and the re-curved RSR 0012 distributor (very good).

The 009 and 050 are also Bosch distributors. Not stock though. You can also use an 061 which was a stock distributor starting in '68.

Not to be argumentative but.....I've got a 050 and a 009 with no mention of Bosch stamped or otherwise, must be that Brazilian or Spanish deal, my apologizes, but I don't see a 061 listed for electronic ignition assuming the PerTronix Ignitor is the issue, at least not at CSP.

Pelican doesn't list a Pertronix for the 061, but another internet/catalog parts house does. Probably would take a call to verify that it is actually available.

for my '66 with a big bore kit and webers, I ditched the original 022 (with the annoying split points) and installed a 031, which improved the performance noticeably.

my stock '68 has been equipped with the 061 ( a vacuum line type distributor) along with a capacitive discharge ignition for years, with good results ( 30mpg highway and passing smog back when required) utilizing the stock points.

'69s used them the 061 as well; if the vacuum hoses and fittings have been stripped off the engine, all those pieces will need to be acquired.

As far as which distributor you have. You will have to get the part numbers off of the distributor. Over the years a lot of these have been replaced with other types. The last three numbers in the part number of the Bosh distributor with tell you, like 022,031, 061, 009, 050.

The 031 is the 061 without the vacuum. It was a special factory option for the Euro market. The 061 can be recurved, with the vacuum removed, to be 031.

I have had a 031 with electronic ignition with a CD box, in my 912R, for years.

[Motorsen]

My is a 009(without vacuum advance)

The one I`m after, must also have the 2-3 degree ignition delay on cyl no 3.

Does any of all the distributors mentioned here, have this?

Ole,

You need to get either the Bosh 031 or the Recurved 009 now called the RS00012. None of these will have a 2-3 degree delay for #3. You shouldn't have too much trouble with heat in Århus.

You should be able to find a Bosh 031 in Europe. The RS00012 is only found in the US in Southern California.

I have the RS0012, it is the best I've ever used for my engines. It's available through.... RSR 0012 Distributor for 356/912
Best of luck,

"Early Bosch 061 distributors were fitted to late 1968 and 1969 912 with the vacuum retard capsule." (CSP), since your car may be a Euro, I'll yield to the powers thinkers.......

My 912 is a late 1969 from California

Your car would have the 061. If it has not be changed. When they got a little too warn. Instead of having them rebuilt the owners would buy a cheaper 009 or later the 050. The 050 would have a black cap. The 009 would have the same color as the 022, 031, 061. You need to take the numbers off the side of t5he distributor. The last three numbers will match one of the ones listed.

The 009 and the 050 are two that you do not want in the car. The 009 is fine if you are only driving on a race track. The 050 is really good for only a VW. The curve like the 009 is not right for the 912 engine.

The RS00012 is a recurved 009 that Benton designed for the 912 engine. It will not work for all engine configurations. It would not work for mine. Benton checked it out and it was a good one. It just did not work for my engine. Most as Clark has stated love it. I found that the 031 worked excellent for my engine configuration. However, it was also curved for my engine configuration. Your car being a 69 should work fine with the RS00012. Much better than the stock 061 vacuum retarded one. If you decide to purchase a RS00012 get it with the Pertornix. You should never have to worry about setting the points or being out of timing.

Hi Jaems/Clark

2 things here sounds good to me and for my standard 912 engine:

1. the original 061 dissy(which I don`t have) added with Pertornix.


2. RS00012 . Will it work on a standard engine?
What does recurved means?

The .061 is NLA new, procuring a used one in good working order could be tricky..I'd contact Glenn's Home Page or shop eBay if you're familiar with that, maybe Jim Easy has one,SF Bay Area Porsche New & Used Parts || EASY - European Auto Salvage Yard that's a used parts house.

The RS0012 is available from the vendor mentioned above Classic Speed Parts, yes it will work on a "standard" 912 engine, it works just fine on mine. Re-curving is adjustments or modifications which provide original operating specifications for the prescribed engine....in your case the 912.........

[Jaems]

The RS00012 is a recurved 009 to optimized it for the 912 engine. The curve is the advance the the distributor goes through from the idle of 4 degrees BTDC to the maximum 35 degrees at 3100 rpms and how fast and smooth the curve is to get there. It is a very good distributor for the street and high performance driving and should do well in a stock 912 engine.

Below is the graphs of the different distributors.

The stock curve on the 009 is rather sharp and flat. Which is not very good for street driving, however, very good for racing.

The 061 has a vacuum retard which was mandated to met the government regulations in the US for 68 and 69. Most folks got rid of it after a while.

The 022 was the original 65-67 Distributor for the 912 engine. It was optimized for the street and a very good stock factory distributor.

The 031 is optimized for the street and high performance driving. It was the Euro distributor for the 68 and 69 model year. There was a kit available as a factory option for the US, for racing only.

The recommendation is either the Bosh 031 or the RS00012. Either one would do well in your car. The 031 may be easier to find in Europe. It was mainly for that market. The are three types of the 031. You would want either the type 1 or 2. The third type is more rounded at the base. Types 1 and 2 are have a sharper edge. I don't have a picture handy to show the first types.

I think I told you that my 66 912R originally came for Danmark.

Thanks for all your help/info

I`m looking forward to get it running after easter.
But first there is roadworthy tjek and 4000$ in "taxes" before i can get license plates.

Question, would the RSR 0012 work ok on my 68. It has the big bore kit and IDF40 carbs. I have a 009 in it now and it wont keep up with my wifes 1.7 Hyundai. I'm trying to think of improvements I can make without spending a huge amount of money. Mark West

[C. Clark]

The 0012 will work on any 912 I know of, but as far as the Hyundai issue....?
009's have been called engine killers, I'm not sure about that, but they are inadequate for the 912, back in the day we used them because that's all there was, stock distributors were in most cases NLA and rebuilders were few and unknown...pre-interent.
Before the 0012 I and others used 050's which was a vast improvement over the 009.
In my opinion the best you can do currently is the 0012.
