Miata NB 1.6 2000 Coil Pack Replacement
Hello guys. I'm having trouble with one of my coils, but the new coils that are exactly like mine are very hard to find, and they are very expensive (200$ range). I've been researching about that and it looks like these cars are produced with a lot of variations in the type of coils, so I'm searching for a subsitude.
My first question is, does the coils from MX 5 NB 1.8 fit on MX 5 NB 1.6? The coils for 1.8 are two coils over plugs, and then cables to the other two spark plugs, and mine are two coils on a frame, on the rear of the engine and four cables to each spark plug.
Mazda 323 from 98 - 2004 is using coils over plugs for two cylinders, and cables for the other two. They look very similar to the ones on 1.8 miata NB, but are cheaper. The connector also looks exactly the same. Would they work on the miata? if the pinout is the same and the distance to the spark plug is the same, I don't see a reason why they would not.
So if all of this works, I could have new coil packs for around 80$ instead of 200, which is a good deal.
Have someone tried something like that?

I bought a coilpack that's for a 2000 US spec not knowing this...I was wondering if we could hack connector and splice in the one that fits.

I think we have the same problem....I have a year 2000 JDM spec and the connectors to the coilpack are different than a US model/spec...mine basically looks like its from a 93-96 model....I do believe the UK/Euro Miatas are the same as JDM...

Yeah, I made mine to work mate. Now the car runs much better it's worth it. Basically, you have three types of connectors for the miata up to 2005. The very early type, that is only for the first years of production for NA are with two connectors per coil, and they are without build in ignitor in the coils. These cannot be used for the later models. After that they had two types - with four and three pin, which are basically the same, but the one that is with four has also a tachimeter output, which they used as a way to detect the RPM of the vehicle. Then they switched to detecting that by other means and they removed one connector , because it's no longer needed for tachimeter output (or maybe the later models started to detect with the tachimeter I can't remember).
My coil had four connectors and my car had three, so I soldered the correct cables directly to the matching pins of the coil, and it worked like charm - hasn't skipped a beat since. You only have to be very careful to solder the correct cables on their places.
I used these site for the pinout of the four connector coil:

and for the cables from my car, I used the colors from the wiring diagram:
B - Black (ground)
B/W - black with white strip (plus)
BR, BR/Y - Broun, Broun with yellow strip (Signal)
You can research more to be extra careful, but this worked for me
