Now I know the MSD makes a wide variety of ignition systems for the import 4cyl. I am running an LS/Vtec in my 89 CRX and I was wondering what would be the best MSD system to run with this....if there is anything you need to know to help further an answer just ask. I want to run the Blaster 2 coil so i need a new cap. or is it worth it?

 

Keep it factory, unless you're running a seriously crazy setup, you're not going to see any power difference.

 

Well I am running an all motor LS/Vtec motor that has a 9500 rpm redline and i know that the stock coil in the dizzy is pretty weak at high rpm

 

No, Honda has very strong ignition systems. They can hold at least 250hp. But if you mind is set on it, then just get the sports compact one. that would be fine.
