Setting up DLI on 20V

[Bazooka]

OK back to the CAS. I have gutted a 20V dizzy, a 2E dizzy and a Mitsubishi 4G67 CAS that has an optical pickup. I was first planning to use the 4G67 internals in the 2E dizzy, using the longer 2E shaft as the body was a bit deeper giving me more room to fit everything in. Unfortunately once I pulled them all apart it just looked too messy to get it to fit. I also found that the Toyotas use a straight 10mm shaft and the Mitsi's shaft is stepped in a few places making it even harder to swap. This also gave a holt to plan B which was to use the longer Toyota shaft in the 4G67 body. After this let down I decided to pull down the 20V dizzy and see what I could find. After gutting it I found it to be quite reasonable inside to be able to mount almost anything having a nice flat base. I thought great all I need to do is drill some holes in the base to accept the optical unit and cut down the shaft for the disc. Now there were a few extra holes in the base of the 20V distrubutor around where the factory unit bolts in but remain unused. To my amasement I found that with using one of the original mount holes the 4G67 unit seems to line up perfectly with another two of these other previously unused holes. Although they are not tapped this would be easy enough to do allowing you to simply screw the whole thing in. The only other thing needed would be to cut out around the body for the plug as it is much larger. The amazing thing is that the plug will still be in the exact location as the 20V plug in the dizzy. This leads me to believe that they must have some sort of connection from manufacture somewhere along the line.
Well thats as far as I have got for now, I will try to take some pics but looks as though this will not be too hard to put together. The other thing is that I will have to make a higher stepped cover to seal the whole unit after fitting the optical pickup. My only gripe is that the 20V dizzy is a bit shallow.

The 16V head is a lot easier to setup like this as it doesnt have the tubes like the 20V. There is a lot more room to use pretty much whatever coil you can get your hands on. The 20V having small tubes needs a very slim coil pack to be able to fit. I found some wasted spark coils from a Daihatsu HD that were the thinnest I could find. These fit down the tubes without modification.

Are the Daihatsu coils inductive - built-in ignitors? any pics by any chance.
