IGN-1A race coils - as used on our turbo Miata
 

http://www.diyautotune.com/images/pr...-1a/ign-1a.jpg

We've been running these on our turbo Miata for over a year, and now we've ordered a batch of them for sale to the general public. These have their own internal ignition module, and work great with the MSPNP line. Check them out here:

So how do these compare to a set of CoP's?

These IGN-1As are the same coils used in the Huber Mustang - a four banger that's running over 40 psi of boost, making four digit horsepower numbers. They switched to these after an MSD DIS-2 wasn't powerful enough. I think it's safe to say they're a good bit of a step up from OEM Toyota coils.

We were kicking around the idea of building a coil testing rig. It would be interesting to see exact numbers, but these coils are straight up nasty. Nearly 3ms spark duration (3 times stock and Toyo coils). Only 2.5 ms dwell period, so it's ok to run them up to high rpms wasted spark, unlike the LSx coils.

Basically, if you're looking for an ignition solution, this is the one to go for.

How are you guys running these? Pictures of setup on car? Looks interesting.

Do I need 4 of them? Do I use stock wires? Are you guys going to make a mounting bracket? Pics of them installed would be awesome.

Yes, you would need 4, and I would recommend running new power and ground connections. Easy thing to do would be to use the existing 12V at the factory coil harness to drive a relay, and grab a good 12V source straight from under the fuse box by the passenger fender.

I will try to get a pic of how Jerry's red miata is set up tomorrow. He has them on a bracket on the passenger side, but there's a lot of ways you could mount them. I was imagining fabbing up a hold down on the cam cover for them, and then 4 short wires (coil near plug like LSx).

In for pics

Can't grab a good picture of how the miata is set up right now, but here's a pic of the 1000 hp 2.7l Mustang that also runs them. That car is boosting 40+ psi and runs 8.90 quarters.

It looks like it needs MOAR BOOOST!!!!

So are you guys just running a random wire from the coil to the plug or something special? Pretty curious.

Our own Miata is using a custom set of Magnacor wires. The coils have HEI type terminals on them.

Id love to do this to my MSM but I have zero clue on how to set them up with the Hydra...(I wish you guys wouldve made a pnp for the MSM :( )

Should not be difficult to set up with the Hydra, either wasted spark or sequential.

We do have a sample 01+ Miata ECU header for DIYPNP development. ;)

I am die'n for these things to come out.

Any updates?

We have them in stock, they've been selling.

If you're looking for a hot coil, this is it.

Holy crap! A 1000hp Lima thats still SOHC?!

What would you use for plug wires on these, though? They look about the same physical size as a standard M1 coil pack, but you need twice as many so I'm assuming they won't fit in the OE Location?

I am curious about what you would use for wires and mounting location as well.

I wish there were instructions on how to build these coils. I'd be interested.

Jerry's Miata has them bolted on the pass fender by the main fuse box and has a set of Magnacore plug wires.

His car puked the timing belt, and we're waiting on parts and an opportunity to get it bolted back up. Once the engine is finished up, I'll grab pics of it. Promise. I'll also get plug wire measurements.

Are these the same coils that 034 Motorsports sell?

Yes, these are the same as one of the coils that 034 offers.

These are very good coils, we have been using 034 motorsport coils on our cars for almost a year now. No problems at all, seems to handle beating very well :giggle:
Next we'll install 034 coils to our miata project car with DIYPNP ecu.

Heres 034 coil setup on one of our clients skyline:

That car would do 8.70's with Jesel finger followers. Just sayin... :p

That coil seems badass though.

How much work would be involved in modifying the MSPnP *non-diy* to accept and run these coils? Is it merely a programing thing or are there hardware changes/updates that need to be made?

Except for a few very early MM9093 units, nothing. They just need the dwell backed off a little.

I'll be in the market for a ignition setup in the next month and I just ran into this thread.

I had planned on going the OEM Toyota COP route, but if this is a better choice I'm down with that.

So if I have a MSPNP 90-93 and was interested in these, would you guys happen to have some sort of writeup or parts list needed to make this work?

I can have a bracket made, do the wiring myself, play on the laptop with MSPNP, but I would like to know exactly what it is I have to do before I buy anything.

I want these badly. ANy clue as far as what Id need to do if anything for the Hydra to work with these? Wiring directions come with them?

Vash,
That's the exact set up (MSPNP MM9093 and (4) IGN coils) currently on our 1.6 S3 turbo car. Works great. The only issue with a 1.6 car is that you'd need a tach driver, since the original ignitor supplies the signal to the dash tach, and these coils do not do that. Our MM9093 does not have a tach driver on board, however the DIYPNP does. We're chewing over the best way to help people with this, and may offer a schematic and/or parts kit so you can build a tach driver.

94.5 and later miatas have ECU generated tach output, so it's not a concern on later cars. For a 94.5+, all you'd need to do is wire/bolt up the coils and set your dwell time to 2.5 ms. MM9495 and MM9697 MSPNP ECUs all have on board tach drivers.

Here is the coil pinout:

A - Ignition signal from ECU
B - Logic ground, connect to ECU ground
C - Spark wire ground, connect to cylinder head
D - Power ground, connect to battery negative
E - 12 volt power

The connector identifies the pins

The only thing you'd need to do with a Hydra is set dwell time.

Thank you very much! Ill be getting a set of these shortly;)

And dwell trim?

Got any out-of-the-box mounting solutions? If I make it, it will be Fugly.

I am still waiting for pictures of how they have them mounted in Jerrys Miata.

Any updates on pictures of these installed in the Miata? I am seriously considering these over keeping my Toyota Cops Setup.

Also where would I get the plug wires from that would work in a Miata with them?

We had some custom Magnecors made for ours.

Chances are if we release a bolt-on bracket for these coils, it will not look like what we put in Jerry's car. That setup was OK for testing things out, but not exactly something we'd feel good about selling. :)

Release a PNP kit, and put me on the list.

for a 94 running diypnp.

So does this mean you are seriously considering making a "kit" for the Miata? I am seriously considering ordering these, but my fabrication skills are less then amazing. If there was a nearly PNP solution I would be one of the first to buy it.

Basically the only thing keeping me from ordering them now is I have no clue how to mount them and that I have no clue what spark plug wires I would need or where to even start researching that information.

I could really use a kit because my fabrication skills are um well just see my build thread :|

Guys could you give some tips on what wires to get? Do we just call up Magnecor and say I need a wire this length with these _________________ specs?

What are those specs :)

In for updates if you ever come up with a solution for my 9093.

Bracket ever happen?
