using a "coil pack" ignition

[eapcpa]

oemexp:
I have used coils from Kawasaki Ninja ZX 600 Motorcycle engines for years.

We want pictures, we want pictures, we want....

Anybody else running these yet. Seems to be a lot COP buzz going on in other forums, many with high buck pricetags that use the 997 COPs with custom valve covers so you can bolt them down. These (and the Audis) just seem a better solution.

Not running them yet, but gathering them for my next project(s).

I just picked up four cheap, including the wiring harness. They are pretty neat! Eight more coils and two more harnesses to go...

Kenik,
Keep me posted. as soon as I complete my current project......it's on to the next big thing.

Which coils are these?

They are the ones I am referring to below.

I did a test fit last night to check how well the Kawasaki (Denso) coils fit our engines. Net-net...amazingly well.

Length: Very good; comparable to Beru plug leads.
Fit: You have to unscrew the spark plug terminals to expose the threaded ends on the plugs for these to attach. The coils, as a result, grab on tight and don't let go. I don't foresee these things letting go.
Plug hole size: The coils are quite a bit wider than the stock plug wire leads, but are still small enough to accept the Beru rubber surrounds.

Summary: These things fit great, hold great and look damned close to stock when using the rubber plug surrounds. I do not see any issue with these, in terms of fitment. If you are worried, it would be easy fabricate a bent sheet metal piece, attached to the closest head cover nut as extra insurance on the bottom plugs.

I say use them! Here are some crappy camera pics to illustrate.

Without rubber surround:



With rubber surround:



For reference, the ones I tested with are the newer Kawasaki ZX9/ZX12 coils. There seem to be several variants between the different bikes - the earliest ZX6 coils look a bit longer, so I'd avoid them as I think these fit awesome. Here are some reference shots of the Denso part number and side profile:



BTW, I have come up with a method using the stock valve covers and the Boxster Beru "bolt down" types of COP, which should be incredibly easy to execute. This will allow these to be bolted cleanly to the valve cover and should satisfy those out there that are "Porsche parts or no parts" in dememanor.

I am going to pick up a used Beru COP to test it, then report back.

These look like the ticket for a COP setup! I have been waiting for something cleaner than a bunch of wasted spark coils for my twin plug setup. You could always modify the plug hold downs available for twin plus wires.

VERY good point - I forgot about these:



Why make them when you can buy them for $60? Sweet.

[jonesb930]

Kenik,

That's what I was thinking. I wonder if you could just do a similar thing with the Boxter coils?

Perhaps, but it would look Ghetto since they have the mounting bosses.

I will go ahead and share my metod for mounting the Boxster coils, so someone else can try it. Since the Denso coils are the way I am going to go, someone else more motivated should try it.

1. As you will recall, the section of the valve cover that the plug sits in is dry (e.g. not bathed in oil). Thus, use a Beru (Boxster) coil as your template for placing the coil on the valve cover, turning it to line up the holes so that the bosses line up within the "dry" area of the valve cover. DO NOT set the alignment so the holes line up over the oil bathed part of the cover!

2. Use a machinist's spring loaded punch to mark the hole centers on the valve cover.

3. Get a riv-nut gun and the proper sized riv-nuts for the coil mounting bosses:


4. Drill the valve covers to fit the riv-nuts, then use the riv-nut gun to set the riv-nuts. This is how they work:


5. Voila, perfect mounting points for Beru coils.

Kenik,

This is exactly what I was thinking, though the RIV-NUT is much easier than what I was going to do. What ignitors are used with the Beru coils?

Bill

[jonesb930]

I just ordered one off of eBay for $44 new part number 997.602.102.00

They have a set of Six shipped for $239 Coils on eBay

I will see how it fits on both top and bottom.

Any EMS should be able to ignite them from the ECU's ignition ports.

Thr Kawasaki coils are nice and looks snugg, but I'm still skeptical. Has anyone of you read the service manual or other Kawasaki information?

What is the impedance?

Not sure yet - I need to look it up.

subscribing, this looks like what i need

Subscribing.

This subject looks really interesting.
I am just starting a rebuild of a 3.6 964 N/A engine for next year's project car (whatever it may be!) and I'd love to try this.
I have already decided to use motorcycle throttle bodies as ITBs, so a nice clean ignition setup would complement that nicely.

Keep the info and photos flowing.

just a FYI megajolt is coming out with a controler for COP next spring, looking better
