I would love to see what you come up with. I am also trying to accomplish the same thing with a twin plugged 3.2SS Turbo motor running an M600 ECU from Motec. I like the idea of using a Porsche part that has the ignitor built into it. O was thinking of trying to fab one myself but I already have so much to do with this build as it is. I am going to try to install some plugs in the lowers to see how it really sits when fully seated on a plug.

I also have no doubt that the spark energy will be sufficient to fire under 1 bar of boost with these coils. I should have no problems having two per cylinder.

I just purchased the single COP to test for fitment from an eBay seller for $44 each (+$5 SH) or $239 (Free SH) for a set of 6 . PM for a link.

Rothsport makes billet top covers with mounting points for late model porsche cop.

I would really like to see a set of those installed.. Anyone using them? THeir site is still being updated for all their products.

Bill,
I was looking into your setup, the M600, I believe there are 6 ignition outputs from the ECU, and they are the drivers for the coils, so, 12 plugs would split and double each respective ignition wire to their respective coil(s), and you need 12V from the switch, and ground for each coil. The 997 COPs have enough energy for your application. I think your car is a street ride, so I could see how wiring and fit are your concern, since we all like things to be neat. Raychem heat shrink is worth the small expense in my opinion..

I am heading to my shop this weekend to remove my Motec igniter and excess harnesses, lay out a rough harness for 6 plugs for now. I have a tool and die guy from Boeing working the valve cover issue for aluminum clips. (We also may be able to open the holes for the COP shaft and get a better fit, then use a larger rubber seal ring, since this is a dry are of the covers.)

We are looking to source the needed connectors, the P-car diagrams do not list the connectors by number, but this should be a non-issue once the units are in-house..
My thoughts on the lower 6 (once I am ready for the 3.7) is to FAB a thin aluminum heat shield, apply heat reflective Gold tape, and add a few thermocouples to monitor the temp on the units until I am satisfied they are ok...
I will post pics and more details as they become available...

Bill, I am sure we will keep in touch off line on this as well....

That sounds good Andrew. I am going to reach out to Rothsport and see if I can get a price and picture for their valve covers as well.

Bill

I took my plugs out of my motor on the stand and realized that I did not have the screw on ends on the plugs. I installed them to get a better idea of how the 997 coils would fit. They actually sit a little higher than shown in my pictures. This makes things a little easier as you will not have to clearance the valve covers for the coils. I also installed my lower plus and found the same thing. It looks like a simple bracket using the valve cover bolts could easily be made. Rothsport's billet valve covers would be much more expensive I would imagine.

I emailed them regarding these covers, no reply.. I am sure someone else makes these.. Dawe?

After installing the coils on the stand I realized that it really would not take much to make a mount for them. I will try to take some good picks for you tonight.

Bill

Bill,
It may pay to just align and drill for studs..Or. I am leaning towards 0.060 T4 bent retainers to go across the face of the coils from stud to stud. Quick, easy and cheap, plus minimal weight gain..
Also, I have tech info from BERU, on these puppies..
still a few weeks out for me.. Need the connector info as well, I put a feeler on the 997 board..
Andrew

I emailed Motec on the connector info as well. These things are in everything from 993-996's so i am sure they have come across them.

Andrew I also shot you an email regaurding the BERU info and mounts.

Bill

If anyone is looking for these BERU coils they are available from our host with free shipping (if you spend $75)!

$43 Each

sent an email to you about the BERU..

Does anyone know if the 997 BERU coils are "SELF" ignited? or, does the DME have an internal igniter? I have been speaking to Motec again, and they, SIMON< have informed me that my setup, the M48, will not split the Porsche coils due to available voltage from the expander, but they will run a 6 pack. Bosch offers a self igniter, the P35-T, which will do the trick, if you can find them.. The hunt continues..

Or, I can upgrade to an M600.. Anyone have one?

Subscribed!

Ok, Latest update to the saga...
After a long email discussion with my friends at Motec, I am out of luck on my desire for COP with my current motec M48 steup. At a minimum, a M600 is needed to fire these BERU coils, an most others due tot he ma require to trigger, which need external igniters per BERU engineering here in the US>

So, I am sourcing a three channel Bosch igniter, to replace my current 6 channel GM igniter, and run my 2.9 in wasted spark, with my 3X2 Bosch Motorsports coil pack, until the Budget allows for the M600 upgrade.
So, there will be a fully optioned M4-8 available with an ignition expander to allow up to 12 cyls in waste moe in the near future..

Wow, not quite sure how I missed this thread. I have this exact project going on to my fathers 89 Carrera. We had to order the connectors from Germany believe it or not. A guy in NY imported them for us and sold them to us in TX. I still have the baggies with PN on them laying around somewhere if somebody is interested.

You said you have info on these COP units, I would greatly appreciate any data sheets you have.

EdHenkel@gmail.com

I'm trying to make these work with our Megasquirt system. I was under the impression they had ignitors built in, only requiring a driver to fire them off?

constant 12, Gnd and a switched 5v to fire?

Would really appreciate any spec sheets!

997 MK2 coil use on 965
 

I just bought 997 MK2 coil ( see photos). and I'd like to use it on my 965. But I don't know if I connect to coil wiring, which wiring is connect to positive which is to ground? the other two to DME? If you want to use it at Motec M1, I need to know what that 4 pins stand for?

thanks for your help and timely answer.
