coils

What engine management system are you using?

Normally, I'd say the LS truck coils are what you're looking for, but, IMO they require an ECU that is capable of direct-fire ignition. They do not work well with wastespark systems, due to dwell time limitations. The AEM/Mercury IGN-1A coils are one of the best inductive coils on the market right now, but they're a little larger than the LSx coils, and are difficult to package on top of the engine like you will want to do to clean things up.

Stop playing with old tech and toys.

Go full CDI, Dynatek is very small coils (bike stuff) and CDI boxes are not large at all and very simple system and reliable and cheap too.

I have been running the above for many years and 10's of thousands of covered real world miles. You can run any tuning you like, any fuel, any ratio, it will burn the lot. and unlike MSD (My Spark Disappeared) you wont have any reliability issues.

If you are in any doubts about Inductive V's CDI go rent a lab scope and test your secondary voltage @ 2k rpm increments to 8k rpm then post back, you will be shocked how much voltage you drop as rpm increases!!!

If you need some help for parts PM me or search my threads.

the aem coils are a little large but doable for my space situation the haltec ls1 coils are a little smaller .i have limited space and a cdi (from dynatek or haltec) is a great idea but want to make it clean .see i dont need the MOST powerful thing on the market ,its a street car .all i was looking for was a smaller coil with the same if not better spark and over all performance .the fact sheet for the aem coils are what i was searching for .cdi is a better system (to me and the dyno )lol but rx2s can be a tight fit for a turbo setup .my car is a 13b turbo with a street port, super t4 turbo at 10 psi and it runs mid 11 in the quarter.that is with the stock coils. as long as that stays the same im good .the next project is changing the turbo to a t3 t4 hybrid ,the boost starts spooling at 4800 with the t4 ,i would like to lower that #,any suggestions are greatly appreciated
