Msd Ignition
 

I how much should this help my performance? I just put it in today just wondering? I guess I should go race a GT or something and find out. Heh! :D

It should help your performance a little bit, especially since your Si is charged...not only will you get a better spark which gives you better combustion...I say you will get 5 to 10 horses out of it.

It will help some but you probably wont feel it. You might be able to increase your plug gap a little and be ok since you have a hotter spark and extract a little more power.
