Hey guys! I apologize, haven't been on all day. Anyway i went on another junkyard hunt for a boot that might work better. What i came up with was a book off a Dodge Intrepid. it needs to be trimmed down just a bit but it works. But to be honest, Im not a fan of how it sits and really would rather do the Protege/Miata setup. Anyway, here are the pictures! I agree with you guys about the mounts, it fairly easy to make some sing they come with brackets.

Hello everyone, thank you for the great information resource ! One of my ignition coils appears to be going out, so I'm probably going to switch to COP. I've looked through most of the thread, but I can't find this info - is the trigger signal from the Miata positive or negative? As far as I understand, most igniters have both positive and negative input, but the COP have only one input. Do the Toyota COP take positive or negative trigger signal?

I'm going to assume when you say positive and negative you mean a logic high or low signal. Miata coils are triggered by a 5v logic high signal.
I have about 7 Toyota COPS and a bracket for a 1.6 for sale.

Thank you, I don't think it's worth it with the delivery costs, I'm gonna by some from around here. The other thing I'm considering is to use an old school separate Igniter, like on the 90-93 mk1 model, and use it with two old school large coils cause they are very cheap - 5-10$ a piece. That's why I'm asking about the trigger signal, cause apparently I'd have to search for an Igniter that takes positive pulse.

I thought I would contribute a picture of my economy Toyota coil setup. still running stock engine management, noticed a huge difference worth every penny. note that there is some temporary foam under the bracket till I get a hold of some thing a little more permanent. also I should add there is a spacer under the strip holding the valve cover down and leaving a 2mm space between the coils and the bar for the foam to fill. any one have any thoughts on where to by 400 degree adhesive backed foam padding?

I'm not sure if I ever posted my solution for LS coils on my VVT Miata. I didn't want to give up the shock tower brace sohad some limitations for mounting the coils. Wound up using a generic e-bay bracket that I modded by welding on an extra piece for support by tying into the stock COP bolt hole. Shortened up the GM harness and used some do it yourself Magnecor wires. Used the wiring diagram from Flyin Miata and tied into the Hydra following their instructions. The whole setup cost about $175.

Hey all, I completed my basic Toyota cops build with no problems thanks to info here. One change I did was go for the new coil pack connectors that Ballenger offers: CONN-86032.
This gives plug and play on the 94 and up coil pack plugs on the car side. ( Didn't see any one else posting about this yet on this thread).
Here's the process I did (how to video format):
