Where did you mount your CD ignition box? I have a Pertronix HP box and I am searching for the best place to mount it.

On my six conversions, always liked to use the two holes that held the 4cyl ECU. Flat piece of metal worked well.

The stock six location is between the battery and the firewall. AA sells the bracket that mounts to the battery tray.

I cut up, welded and modified a stock repop /6 CDI mount for my MSD box, cool thing for me is my twin plug dizzy has a MSD trigger and by mounting it in the stock location I was able to plug it directly to the box without an extension wire.

The MSD box tucks mostly under the battery tray, the SS access port cover you see is so I can change the RPM 'pill' without removing the box. All the excess MSD wiring tucked nicely in the the battery tray stand.

Here’s how I mounted a MSD box. I fabricated the mount

I can not mount the CD box on the fire wall behind the battery, I am running Ljet fuel injection. The ECU is mounted in that location.

Maybe over by the relay board? Isn't there a little room between the board and firewall?

The MSD has long wires, firewall, rear trunk, etc.

What CDI do you have? Might help us help you.

Pertronix HP. The box is about 2/3 the size of an MSD box.

I already had junk in my trunk.

3.0 liter with CIS.

That looks like a great option. The engine compartment is too cluttered. Thanks for the response.

I have to revisit this myself now. The PO mounting the MSD 6AL box in the trunk. It was the one thing I thought I would leave alone and just re-install after paint. Not certain about that now. Just a couple of sheet metal screws straight into the firewall too close to the jack. Ugh, sort of wishing I welded those up.

My battery tray 4-cyl ECU area is taken up by CIS filter and accumulator - Actually very clean. The relay board is gone, but have all the oil tank stuff in the way.

Could be I'm stuck in the trunk. Anyone have any pics of alternate locations for a CD or MSD box? Looking for ideas.

Put it on the firewall on the left hand side. If the angle bugs you make a simple mount bracket.

I personally don't like the junk in the trunk.

You risk knocking something loose that is essential to keep the 914 running if your spare tire or luggage slides into it.

Thanks Mark and Clay. I think you nailed it, I'm short on space with the CIS and oil tank bits, but there is room on the middle/left side firewall. Backpad is out so I can install nice vibration mounts.

The spare tire is bolted down.

?? What else are you supposed to use that factory supplied threaded hole for ??



The "luggage" are tools and spare parts. They are securely wedged in the corner with no place to go.
Catastrophic forces would be required for them to interfere with anything essential.
