How to wire in LSx coils ?

Anyone have the info on how to replace stock Miata coils with LSx coils ?

I've got several sets of LSx coils and might try this, if I can get the conversion info/weblinks etc.

Best bet is to search clubroadster or m.net, but I think the dwell would be wrong for miatas. Rev9 makes a really good kit that is plug and play for $250, and lots of people have issues even getting toyota COP's just right. Someone on here is bound to know more.

I'd go to miataturbo.net for this information. Assume you've got an aftermarket ECU? I'm running Toyota COPs with a Megasquirt on my turbo car. Pretty nice, but you do need to reduce dwell time compared to the Mazda coil pack.

On a normally aspirated car, I'd recommend against implementing a solution looking for a problem (unless you have the unreliable 1999-2000 coil packs).

Hornetball is correct in checking on the turbo board. Clubroadster is not the best place to check for that type of info. They are more the "looks" crowd.

My bad.

I've been looking into this myself. Honestly the wiring part is easy if you do some searching (should be almost identical to COP wiring).

From what I've found, the dwell/charging time is very similar to the stock coils. Close enough where I'm gonna just run them as is and see what happens. The Toyota COP setup has very different charging times, hence the need for a programmable ECU.
