I have a 91 Rx7 Convertible that I've been trying to bring back to life. After replacing half a million things that I know were wrong, I set my TPS using the resistance method, cross referencing a Haynes manual with the FSM and an online guide, and got it pretty spot on. I tested the resistance of my coils following the haynes manual I have and the trailing coils showed 0.00 ohms and the leading showed 0.02 ohms. The haynes manual says that it should be between 0.02 - 1 ohm resistance. I want to change all the coils but I can't afford OEM replacements. I was wondering which aftermarket coils I should use with an otherwise stock setup on a naturally aspirated car and how I would wire them in. Thanks for and help!

 

left you a PM to two people in your area that may be able to help with the issue. That's too electrical for me lol

 

Why replace the whole coil? why not replace the individual packs that are bad?

 

better yet,I would like to know why you seem to think that the OEM Coils cost you an Arm and a leg,when you can pick up a used set for like 50 bucks!
The OEM coils are good to about 400 HP so it's not like you are gonna need the "extra spark" of Costly aftermarket Bling on your N/A!

 

He makes an even better point.

 

The stock FC coils are good and plenty powerful as Styx said. However, if you're dead-set on aftermarket ones, I created a schematic to use GM D585s on a stock FC
