Is anyone aware of dual post coils with integral ignitors? Ive heard that Subaru coils have the ignitors included.

Im working on the ignition on my car (twin plugged, w/engine management), and would like as clean a installation as possible

Thanks

the chrysler/mitsubishi coils are a clean installation- as are the gm. also the denso single coils in a coil "rack" are expensive but come out lookinf nicely done. which efi system are you using?

Im looking to eliminate some wiring hence getting coils with integral ignitors.
I have been a part of tuning engines with electromotive,haltech, and Link.

Im trying to really streamline the wiring.....actually trying to find coil on plug set ups that will work on a 911

In that case(wanting coil-on plug) look into the audi and bmw units- I think the reach on the bmw units will be about right- Likely be able to use the ones from the 3 series. The issue will likely be securing them, although I have this sorted out- email me and I will share my technique or you can have me just send you the pieces you need.
If you are trying to streamline your wiring I might also be able to help with some suggestions and other tips- as it happens I am in the middle of wiring a World Challenge BMW(Touring) and several World Challenge GT(Corvette and Porsche) cars so I am in the wiring frame of mind at the moment.

Ive toyed with the idea of a coil on spark set up. You could hold the coils and connector in with a hold down similar to the lower plug hold downs the factory used, or even machine a billet hold down that spans the length of the valve cover (after installing some longer studs) This way you could even throw away you spark plug wires ( what will I do with the magnecors I just bought?)

I have found a source for various beru coil on spark connectors, and will toy around with this idea

From what I can tell you still need an igniton module or ignitor to fire the coil. This would make a clean and intersting installation though.

No way in hell I could run in SCCA with this type of set up.

I have scoured theparts books and have found bosch single output coils with intergral ignitors.. but no two tower coils with integral ignitors..... maybe they dont exist.

I have a customer car that will be running SCCA with a coil-on-plug setup in a GT-2 car. There isnt a restriction on spark ignition.

I wouldnt use a strap-type hold-down to hold them on, Instead I duplicate the BMW set-up with studs- so far we have- carefully tigged them on, through bolt and epoxied them on, and made an aluminum "frame" that holds them. Through-bolts and epoxy worked best, using countersunk allen screws and careful maching.
the BMW coils need no ignitor with a proper engine management- I am currently using them with a DTA unit with no issues. Motec requires the ignition expander, but thats it. For the BMW units anyways. I am not sure what coils we have on the Pro cars (911 Speed GT), but will think to look tomorrow. Not like we ever do anything with them, every 30 hours they go to Porsche MS to be "freshened", so I cant say we even change the plugs.

Im guessing you are using the BMW coil with a connector of the required length.. I know some of the BMW coil on spark units are much longer than the porsche wire connectors.

I have experience with Haltech and Electomotive management. Helping a friend of mine who is in the performance business set up engine management. The Link has 8 ignition and 8 injector drivers.

Do you think the Link can fire a coil on BMW coil? or do I still need an ignition module.

I have no idea if the Link could fire the bmw coil but I doubt that it would have trouble with it. I use the BMW coils using a BMW connector "pigtail" to a 36 pin milspec connector at the firewall, then straight to the ecu. Haltech and electromotive are both decent units, but I find electramotive niether flexible enough nor fast enough for most of my race applications, and haltec is just outdated- for the same money you can buy much more ecu- if you are currently in possession of the units then my best advice is to tune tune tune, and log the lambda readings on the track.
If the link will not fire the coils you might be able to use a msd or comparable DIS box, using the ecu to just trigger the msd. I have seen this setup on various imports, and it seems to work well. Just make sure the box you buy is for Distributorless ignition systems.
