Default Distributor and wires

I have a 97 and a 96 seei and wanted to know what type of MDS distributors I would need for those cars. Both of them have the S2 engine and the M90 supercharger. the 96 though has the 3.4 Supercharger pulley. I have done a little homework on the wires and the distributor. Here is the information that I have found. The distributor MSD Coil, GM Coil Pack, 2 Tower Style # 8224 and the wires MSD #32789 8.5mm. Would these be the right ones? I also would like to know if I would need anything else like special spark plugs. Where would I be able to get these parts for a great price? The reason I ask is because I want to make my bonni go really fast. What else would you guys recommend? I would like also if people could provide some links or information on where some of the suggested thoughts/parts can be found. Thanks

Is something wrong with your stock coils? I recently saw several people run mid 13s at the track with the stock series ii coils. Basically what I'm saying is that I think you can do better mods for the money. You mentioned a 3.4 pulley. From my experiences you need a well designed intake and one heat range colder spark plugs. I run autolite copper plugs but have also run the ngk tr55s. The parts store will often try to sell you a platinum or irridium plug, Iridium will work but copper is 1/5th the price. Most seem to prefer copper on a modded 3800sc. MSD wires are decent quality but you can get just as good for cheaper.

Have you scanned your car with a scantool for Knock or (KR)? This is very important when you drop a pulley size to make sure your car is running properly?

There is a large afermarket for your engine. Many vendors out there sell parts for these cars and packages to get you started.

I've personally bought stuff from Intense Racing and ZZ Performance and both were good to me. There are several other sites out there...

I'd reccomend you read this article about modding a bonneville:

Stock coils are not a restriction until you are running very higher boost. Much higher then a M90 can push. That being said I have the MSD coils (PN 8224) and I felt better throttle response with them.

Plugs and wires are a tuneup item, not a power-adder.

Stick with standard 'copper' plugs from AC Delco, NGK, or Autolite. They are the big 3 here. Don't buy performance wires, either. The added insulation is of no benefit to you. 7mm Belden Premiums from NAPA will net the same power as the most expensive wires you can find.

I'm moving your topic to 92-99, as the subject isn't performance related, but actually just standard maintenance.

As I stated in your other topic, you don't have a distributor, and MSD coils are only marginally 'hotter' than your stock coils. The older cars here may notice a difference in a smoother idle, but 97 and newer supercharged probably won't.
