I have a 1979 924 which funnily enough has points in the distributor Im sure its a 1979 model cause the chassis no states so. I would like to swap/eliminate the points and install an electronic ignition system or an original Transisorised ignition which is stated by Hayes as supposed to be installed. I would appreciate any info on this too. BTW guys thanks for all the info your sending or posting on my other threads, As soon as I start the project I will be posting some pics (if i find a way to) Im also using search as my friend as recommended.

Thanks

I have a rebuilt NA ignition distributor and an ignitor box (not on my site yet) that are both available. However, these are US parts and may not be ideal for your application, unless you had the distributor recurved to Euro specs.

EFI (electronic fuel injection) is not a trivial conversion. I am working on developing some bolt-on components, including a fuel rail, and crank trigger wheel for electronic ignition, and I've found a source for flow-matched injectors. However, there's more to it than that...you still need to find an ECU, either an open source Megasquirt approach, or an aftermarket product like 034Motorsports, DTA Fast, VEMS, or a number of others. A thorough read of the Engine Management section of the Performance Upgrades thread would be a good idea, as it will help you understand what's involved with an EFI conversion, point you to several examples here, so you can judge for yourself if EFI is a path you want to go down.

One other option is sort of a hybrid approach, and that is to retain the stock CIS system, but to replace the warmup regulator with the so-called "Digital WUR" from Unwired Tools. The NA version is not much more than a rebuilt WUR, and personally an option that I find very attractive.

Regarding the ignition components, I believe PET confirms that the ignition unit itself is the same regardless of market (US vs. ROW), but I will double verify that this evening. Regarding the ignition distributor, I've confirmed that there are definitely different part numbers between ROW & US models, so you will definitely want to find a ROW distributor from somewhere in Europe. If for any reason, you can't find one, then the rebuilt US version I have could be recurved, but I think it would be best to find a ROW version, and I suspect probably not too hard. You could probably get both units from the same donor car if you find someone breaking a ROW car.

I´m thinking about doing it to my n/a me to. Its not so fun to adjust them all the time (which you have to when your engine spends alot of time between 4500 and 6000rpm at the track). And the distributor is getting a bit sploppy. What i heard to be the easiest way is to get hold of a distributor and then take ignition module plus wiring from a car (an old saab for example which is common here) at the scrap. The distributor is found on later 924s.

Yes, it is compatible, it's for a 1979-1980 NA, US market. It's up for grabs

About 6 months ago I was offered a points distributor with a contactless lumenition PMA 50 modification. It had been taken from a '76 924 Euro.

Don't know if the guy still has it, but PM me if you are interested and I will send his contact info.

It's located in Denmark.

The easiest way of changing to electronic ignitionis to swap to a after market unit such as Pertronix's.

I recently did this to my 1979 924 Auto. Which also had points. It was as quick as replacing the points and once done you never have to open the distributor cap again. Sequence is remove distributor cap, remove the points and capacitor , install the electronic module set the gap using the guide supplied and connect two wires - one to the positive side of the coil and the other to the negative side. Put distributor cap backon and it's all go. The Pertronix part you require is a 1847V (or that's what I installed in my car) in New Zealand I paid the local supplier NZ$145 (USD$110)

I also did my Nissan Patrol off roader last year and it was a bit more difficult as I had to machine the distributor shaft which required the distributor to be removed.

I have put similar systems in other cars with good results.

You have to tune it after, not a straight drop in and go.
