Well guys being the bargin hunter I am I found a CDI unit on eBay for $50 + shipping! It was supposedly used in a shop on a distributor test bench and never installed in a Car. I'm sure it will work just fine, however when I got it today I couldn't beleive how large it is!!! Sucker is 6" L 4" H 4" wide BIG, like the GM AirCompressor it looks like it should be under the hood of a Dodge 440. I guess with new electronics technology I can see even these are smaller now days! Here's a couple of pics.

I'm presently running the compufire electronic converstion and a Bosh Blue coil so this will hopefully play well together.

Keraaaaack!

Did you notice that the device draws a maximun of 15 AMPS! No wonder it has such a large heat sink. It must put out sparks like a Mid-West thunder storm.

Mallory CDI

I used one of those for a few years on a 59 Studebaker and still have it. If it breaks Mallory doesn't know anything about it. It is so old, I was told, that no one there has any idea how it works. It puts out a spake that is like a blue ribbon. Wide and blue. The original ignition I was using made a faint yellow pin of a spark. This unit is awesome. I did, however, use a matching coil made by Mallory for CDI's. A MALLORY VOLTMASTER MARK II number 29150. If you don't want to use it let me know as I would like to have a spare in good condition.

Will any bosch blue coil work on Opel GT?

High energy ignition systems can lead to some funny things.

Naah the center electrode along with insulator is still intact.
Just a bad camera angle.

You'll run into this problem when certain conditions are met.
i.e.
spark timing high
High gear ~45 mph
slight load (small incline)
lean mixtures
