If you order COPs online from a junkyard, do you get any of the harness with it or do you just get a lone plug?
Depends on the junkyard. If they let you pull your own parts just be sure you grab those plugs while your pulling coils. Try to cut the Toyota harness as far back as you can so you have a long length of wire to work with. I bought my coils off ebay and found the connectors in a local junk yard. I'm there all the time so they didn't actually charge me for the connectors. They just waved me out the door and said don't worry about it. They make the most money off larger parts.

The cop coils in that pic are different then ones I'm recomending. It looks like he's using AEM's ignitor because his coils don't have an internal ignitor like the Toyota coils suggested. The best source for the Corolla coils is Ebay or another site someone recomended. Browse thru the thread you'll find it posted.

beer,
I also had no joy at pull a part. they don't have anything that new. I also called around to all the local yards to no avail.

Saturday I put in a few emails to junkyards that I found through a search at car-part.com. Hopefully I will hear back from at least one Monday. If I get a second response, I will send it to you if you want.

Post something on Toyota, Scion, or MR2 (or something) forums. I'm sure some of those guys have those coils laying around. Or try some performance shop that specialize in Toyota. Worth a try. I haven't been to my junkyard in a few weeks. I'll look again soon.

Why would those guys have extra coils? Are they upgrading to something even better?

If any of you guys live near non-shitty junkyards and have extra coils, I'll gladly buy them off you.

Alot of people run MSD. But do you want to run a $750 ignition system or a $50 ignition system that's quite capable of working better then the stock Miata ignition? There's always something "better". I'm a Miata guy and I have extra coils laying around. Why wouldn't a Toyota guy? The odds of finding Toyota coils on a Toyota forum are alot better then finding them here.

Has anyone dyno tested the difference?

Also, anyone know where I can get another 3-wire miata ignition harness? Junkyard? I'd like to be able to quickly switch back and forth between the two setups by switching harnesses.

Use the one you take off.

Dyno difference? Well, generally speaking you either ignite the fuel in the combustion chamber or you don't. The cop conversion deals with the problems (misfiring amoung other things) the stock ignition has running high boost levels. I'd guess on an na Miata you wouldn't see a difference on the dyno. In a boosted car you will because the stock ignition isn't firing correctly.
No offence but you seem kinda picky asking for minimal (if even measurable) dyno result differences in a DIY thread where most of us are on a budget. You ask many questions danielson. :gay: If your worried about performance go all out with an MSD ignition.

Hey lazer your pm's are full.
WTF is with these msd's i see do i wire it in place of my igniter to drive my coils or can i use it and drive universal coil sets ive seen a rb26 with 6 coils packing 60K apiece, i would love alot more spark performance. I wired in some revtech coils last year 70k volts suposedly but they suffered from a misfire in high boost. And i was wondering if you could outline how to get alot more spark to my car. I know on my chevy it made a huge difference stepping up to 60K volts, my bike did as well with the revtechs, and i hope the miata can benefit as well. The msd website is way to vague for me to sink the money into the project you know

Yes i posted that in response to the Erich Moraga coil plates that bolt to the cam cover.
Those are 300M coils with no integral ignitor, using an AEM Twinfire to fire them. Coil connectors are from a Supra - harness is supplied with the Twinfire, then i just covered it with some 'wiring harness cover' to neaten it up.
I cant honestly recommend the Twinfire though - im on my third, and only done 250 miles total....

On the Miata side (for 1.6) the yellow/blue goes to the gauge and the black/white goes to the ecu. On the 94+ (with internal ignitors) these are connected together. I don't know why Mazda did this on '93.
I do know Mazda ran sequential injection on the '93 California cars.

I just found an 01 Echo in a junkyard yesterday, so I now have the connectors.

Tonight I'll start cutting and soldering... and taking pictures.
And my coils are from an 02 Prius.

Cool Sean.

I should have some COPs tomorrow, but I've got some other things to deal with first.

Dave, do you have your COPs in hand? Can you take a pic of the terminals for me? I'm not planning on trying to source the connectors. Was going to probably use some crimp on spades or something.

Pic please?

I saw all sorts of crimp on pins at Tyco... Minimum quantity was a mere 1,000.

I have an extra set off of a mr2 if anyone needs them... $35 + shipping. Anyone interested? PM me (sorry for the "for sale" in the thread). I'll try to source connectors as well.
