ignition coils ?
 

do you have to use the bosh coils that are hard to find now or can you use your stock coils or can you use turbo II coils?

Well yes to all those, afaik. It all depends upon what you want to do and what microtech you get. Correct me if im wrong but i think this is how it goes:
LT8,10,12s uses the factory coils.
LT8,10,12s with x4 or x6 box uses aftermarket coils.

who said they are hard to find , i use the bosch coils from nissan maxima or stanza they are all the same and cost around 50 each new.

rx7 store used to sell them but its off there site now where can i find them?

At Microtech

I run the Crane LX91 coils with two amps.... very very smooth if you're looking for an alternative to the bosch coils
