Ignition Coil Upgrade

[Drfatz]

I am thinking about upgrading my coil pack with something from the aftermarket. Is this worth doing or should I just purchase the GM units? Also, what aftermarket options are available?

Graham,

Check out Dermot's site http://www.lotusesprit.org/ and see the engine chapter. Dermot fitted an MSD system.

Graham,

MSD has drop in Units, Accel, as well as Crane. Check out www.jegs.com or www.summitracing.com. The units are about $45 each and you need 2. The biggest benefit is the aftermarket units require less primary voltage to charge and fire with more joules of energy vs the stockers. I may fit some at some point and dyno to see if there is any improvement. The GM units are quite good and usually don't have problems, are you having more issues?

Stay away from the Accel units, they are cheaply made crap. I can't speak for the others, but the GM parts are of very high quality.

I've never used Accel stuff, so thanks for the tip Sanj. I have used MSD and Crane ignition amps and coils and have never had issues. The GM stuff IS very high quality surprisingly.

I just got my baby back from paint! She looks fantastic. I have tons of pics and will have to post some up later. I think I may just drop in a set of MSD coils for good measure. Then all of the sensors/electronics will be brand new.
