If they have the igniters built in, they should work. I though you were using the VB921 to drive two coils in prallel.

Nology has some nice igniters and motorcycle coils BTW: http://www.nology.com

I'm not sure of the MS coil driver can drive two coils in parallel, but the configuration should work. Why not use GM twin tower coils, that way you are driving only one coil per driver.

Late 80's RX7 twin tower coil packs have an intergrated driver that will accept a 5V TTL input. I've used these on a number of 6 cylinder turbo applications with good results.
