I actaully have all three in my hand. I have a Magnavox, a Delco, and a later supercharged Delco ( 1998 I think ). From what I have read, I need the 1998 SC right ?
All the ICM'* look the same except for the colorof the ICM where the pins connect.
My car ( 1992 SSEI ) came stock with the Delco unit. I want to make sure that the later 1998 SC version is better, faster, stronger , more jolts.
My end goal is the most reliable spark for the the least money. Am I on the right track ?

Bill: do you have the stock '93 ICM? If you don't have it, nobody needs it. You won't need anything more than some aftermarket coils which will bolt right up to your current setup.

There you have it my friend. If he is good with the factory ICM, then you will be too. If you need the ultimate in power, go for the DIS 4 ignition box.. a few members here have them, and are happy with the results.

With your extensive list of mods.. you won't see a difference witht he DIS 4 box. Just bolt up some MSD coils and give it a rest man! You arn't going to see a difference between a '98 ICM and yours, with the same coils. You probably won't see a difference between the DIS 4 box and just the factory setup, until you start messing with some real performance goodies, such as aftermarket ECU, Valvetrain work, CAI, n2O, etc.. Go with just the MSD coils for now, then later on you can always upgrade to the DIS 4 box.
Oh yeah, the DIS 4 box is a capacitive discharge controller,which acts like your ICM, controlling when to send spark. It has quite a few features such as two rev limiters [one is whole shot, and the other is a reg], multi spark [which gives you multiple sparks between idle and 3000rpm]. Other stuff too, but I forgot what it all was. It is made by MSD, check out their website for a little more detail.

Excellent ! So I have the baddest , hottest most jolts for my money. Thats'* good.
I don't mean to come off as radical . I just hang around some pretty fast company.
I have several friends and customers. that drive hotrods. I just think it'* cool
driving a 4 door luxo barge that will outrun my budies '67 Camaro.
I want to run high 13'* while drinking a Starbuck'* coffe with 2 guy'* in the back seat.
Umm.. kinda like an M-5 or an AMG Mercedes concept. So far I've invested less than 2 car payments .... that'* the magic.

Car payments ? Ahahahahaha .... whats that ? I don't have any of those.
I drive pieces of crap so I don't go into debt. I paid 500 bucks for this car with a bad PCM amd ICM. When Im finish I won't even have 3 cars payments invested.
I pay cash. Fix 'em. Dog on them for a year or two and sell. My parts and mods are my payment. This car new could easily run 450 a month. I got 2 months worth of payments invested so far. After the thrid .. I'm making money everytime the key turns.

Besides that the whole beauty of being on here . Taking a 12 year old car. making it faster and more relaible for less money. Yeah I could go out and buy a new Z-28 or Mustang, but where would the fun be ? I could buy three of these cars in one year for what the payments would be on those cars. Fast , relaible and cheep.Can't have all three, but I can get 2 1/2 of them and still afford the beer to work on it !
