And... paying for a set now... thanks for the legwork Lazzer.

I used car-part.com btw... lots of single coil listings... but I searched and found a set of 4 for $40

 

Correct. You only need one output from each pair. It's just somewhere to connect the other tach wires. 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 picked up a set via car-part.com from a junkyard 15 miles away. 45$, they are from an 03 corolla, 50k miles.

They wouldn't sell me just the connectors for them though, Haven't called the toyota dealer yet to see how much for the connectors.

Thanks lazzer.

 

I found a set of those (02 toyota corolla-will they work?) for $50, checked (my friend checked them on his car.lol). Is that a good deal or no?

 

Yes.

 

All you guys finding the coils in junkyards please keep an eye out for other cars using them and maybe pick up an extra set to sell to the others on the forum that are having trouble finding them.

I'm still keeping an eye out.

 

Lets also look for a cheap connector solution. I know its on my mind.

 

+1.

Cheap connectors would be great.

 

Try the Dealer. Sometimes (rarely) little things like that can be cheap. I haven't actually tried Toyota yet. Maybe Denso can be contacted directly for replacement (...or whoever made those plugs).

 

Apparently they wanna sell me a entire car harness

 

updates??

I need to get moving on an ignition upgrade...

 

Looking on car part.com, should I order any of the following:
2001 Echo
2004 Prius
2005 Scion Xb
Each set is $50

Thanks

 

Updates to what? I have them running on my '94. I've verified the 1.6 can fire the coils and posted both cars schematics to wire them. Honeydesean has a 1.6 and is sourcing the connectors so as soon as those show up we'll should hear a 1.6 success story.
I pulled my plugs out yesterday to replace them and besides one being burnt to a chrisp from detonation the other 3 look great! lol The gap on them was .045 and these coils are firing them with 10psi of boost with out one missfire. The stock coils were working when I removed them but every once and awhile I'd feel a miss. I have no doubt the COP can handle more boost even if you run the standard gap or recomended .028-.032 gap for turbo Miatas. Startup and and mpg is still much better. Remember I'm running sequential but originally I fired the COP wasted spark. Going to sequential didn't provide any additional improvements for my gas miliage it just allows me to trim timing per cylinder. I take off an extra 1 deg under boost for cylinders 3&4.

That's all I have to update for now.
The only trouble I had with cop was the ticket for doing 45 in a 30. :gay:

 

No really looking for an update on Sean's progress. I have a 1.6. I don't know what his connectors look like, but is there not a crimp on connector that will work? Or solder leads and fill with epoxy?

Looking to move forward as I'm having ignitor issues. Would rather spend $50 on COPS than $25 on another used ignitor, if it solves my problem for good. Not willing to chance blowing my expensive ecu.

Any comments on the COPS I listed in post #134?

Thx

 

The part number on the coils I used (from a Corolla) is 90919-02239. I know these fit the valve cover and the reach length down to the plug. Post #84 Flippy used a coil that looks a bit different then mine. The plug is the same it's just the mounting tab is in a slightly different location but they fit. Toss him a private message and get the part number he used. Please post it when you do so we all know what works. Isn't that a 1.6L in the pictures? There's no reason you couldn't solder the wires into the coils and fill it with epoxy. Somewhere in the thread I posted the pin out. With the business end of the coil facing down and the plug facing you the pins are, (from left to right) Ground, Trigger, Tach, Power.

During my testing @12v (small 4ah battery) It'll throw an orange spark 1 3/4" long. -damn- Does anyone know how how many volts it takes to ark that far?

Another note: The coil fires on the falling edge of the trigger pulse and if the pulse is held high it will fire on it's own within maybe 1/2 a second. Probably to protect the primary winding, driver, and car's wiring. Smart coil.

 

I don't have a junkyard handy, which coils will work? Any 2002+ toyota are the same?

 

2000 up. There not all -exactly- the same.

 

Well I took a little drive to the pick and pull south of town and as expected they didn't have any camrys or other toyotas newer than early 90s. Saw one early 1.6L miata.

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?

 

I'll be "upgrading" to COPs a little later. For now I just have to get the car on the road and start braking it in...

 

How much does that little bracket cost? It looks nice. Also, how did you guys get your harnesses to look so neat? Is that how they come out of the toyota?

Also, anyone have any recommendations about where the best source is for COPs?
