After seeing ISC racing's kit to use the chrysler app MSD coils for the 1.6, I decided that i'd finally have a use for that coil i had in a box of neon stuff leftover from my neon days. From what I understand, the miata coil is 26kv and the neon coil is something like 32-36kv, so there's an upgrade to be had here.

I'm afraid i didn't photograph every single step, so i'll do my best to explain.

Here's where i started, with a normal 1.6 valve cover:



First, I simply sat the coil on the valve cover and bravely closed the hood. Hood clearance was not a problem, and the final position of the coil is a bit closer to that hood brace.



Then I made a mock-up out of cardboard:

I measured the bolt-hols and made a a mockup of a bracket for the coil out of cardboard:



Here's the drawing i made from that:



A friend of mine has a bunch of machine shop stuff in his garage, so he made this nifty aluminum mounting plate from the drawing out of scrap aluminum sheet:



He also trimmed down some tubing so that the plate would sit nicely above the valve cover:



We had to make the tubing standoffs a bit shorter before the final fitment with the ingition wires. Caldera hooked me up with his original equipment mopar wires for some extra WTF factor. :)



Once i spliced the wiring together, it started up and ran just fine! I just matched up the wires from the miata coil, 2-3 went to the right terminal on the neon plug, and 1-4 went to the left terminal on the neon plug, common ground goes to the center terminal on the neon plug.

I haven't driven the car tonight, as it has been raining; but i don't imagine the results will be too dramatic since my motor is essentially stock. However, it was a fun project to take on. Thanks for looking!

the neon wires were long enough, wow who knew!

whats to gain from this?

edit: went to the site...

"
Provides 36,000 volts for hotter spark
We have seen as much as 6HP increase

Easy to install, bolt on and splice 3 wires
Will work on any computer"

Drove the car today, there is certainly an improvement at part throttle. My car probably runs a bit on the rich side due to the untuned RX-7 airflow meter, so this seems less prone to missfire under a rich mixture. I am sure the dead thermosensor for the ECU is causing it to run rich as well, so this is good stuff!

this is interesting. may sound like a n00b but if i done this i could mount the coil wherever i wanted right?
Yes, however you'd be on your own as far as ignition wires go. I've seen on other cars where you can pull the boots apart and mix&match. In my location you can use an OEM wireset from a DOHC chrysler engine.

I still have a MSD coil from my DSM N/T days do you think I would be able to use this on my 99'. I don't know if the NB's coil pack is stronger than the 1.6 or not, we all know it's going to go out sooner or later anyway why not replace it now.

It went pretty well:



But that's another topic for discussion later. :) I can't say i can really tell a difference full-throttle performance-wise (as was my expectation), but the engine is definitely happier at daily driver type speeds and loads.

Great job!
I believe an igniter from a 1.6 is needed to install on the 1.8 cars though.

I am attempting the same upgrade as my stock coil has died. Can you better describe what wires go where.
