Default Magnavox to Delco conversion

Figured I may as well post up my results on the magnavox to delco conversion. Here'* the skinny guys. I bought an ICM from Randy [randman1], and Mike [95nasta]. Both look EXACTLY the same as far as mounting and such. One is from an S1, and one is from an S2. So, that DOES NOT matter. However, a little modifying does need to take place. Since I still have the ICM and Coils still all assembled and installed [comming off soon], I don't have what I actually did, but I will explain it. I had to get a couple of bolts.. what size? I belive 1.5" which hold the coils to the ICM. Also a couple of washers will come in handy. Then, I had one mounting location on the original ICM I had, that semi met up with the new ICM.. so I got got a shorter bolt [1/2"- 3/4" will do], along with some washers, and bolted up the ICM to the bracketry like that. Now, one bolt won't suffice, now will it? So, I noticed that there was another bolt hole that semi matched up, but was a little off. This is the bottom right hand corner of the ICM. So, I have that coil mounted up on to the ICM, and also through the bracket. Washers will be needed here too. You will have to enlarge the bolt hole on this side for the ICM. Just about 3/8" taller will do, and a dremel will do this in less than a minute. Unfortunatly this also eaves us with the problem of getting to the bolts for the coils. But, there are only the middle and top coils that don't have bolts on the right hand side. there was enough space on the other side [because of how I mounted it] to accomodate bolts there. So, i'm only not using two bolts, which isn't too bad, and the ICM + Coil assembly is kinda off center.. View the pics to see what I mean.

As Little test, I had flooded the car previous to installing all this stuff [I did this purposly], and tried to start it with the magnavox. No go [flooded some more, because I felt like it]. Installed the delco, started the engine [took 4 cranks], it sputtered, gave some gas, and engine was clear as can be. What would have taken 5 miles on the magnavox, took just a tap of the gas with the delco. I recommend this upgrade to EVERYONE with the magnavox ignition.

Wow, that explaination really sucked. I'll do a better one when I can take pics of what I all did.

That looks like you bolted the coils directly to the engine bracket. On the SII (at least through 1994) there is a thin plate that goes under the module and the coils screw to that. The there are three studs in the bottom of the plate that mate to the three holes in the bracket.

Are six coil screws and three studs. Perhaps this will make more sense:

Default spark

Last winter we had a day around 2 deg. and my SSE would not fire util I pushed
it into the sun and warmed it up.
I wonder if upgrading with this coil setup would help or just pop one on from a 93?

The whole Magnavox ignition is flawed. Personally I am against it fully, the only reason I still have my ICM+Coilpack is for diagnostic purposes, and just in case my delco setup fails . If you have the opportunity to upgrade to the delco ignition in your '90, I say go for it. You can use the whole thing from a '93. Also, after you have tested it'* operation, a tune up is in order. Because the lower voltage put out by the Magnavox often times limits the spark, when upgrading to a higher voltage. This WILL NOT affect the operation, but you should see more of an increase in spark energy when a tune up is done. Also use the plugs/wires for a '93 N/A, and the gap for them too.
