My coils took a crap. I have access to both T2 and RE coils. Any reccomendations? I will be replaceing both leading and trailing. Rest of the ignition system is stock. Thanks.

T2 coils are a very popular choice. Guy who go single usually get T2 coils, so you know these will hold up to big power. I'd say stick with T2's.

the stock coils will support 400 hp

problem is they get cooked to death

Go with turbo2 coils if you have access to them...

iirc all second gen coils are the same, so perhaps this will help you find a set.

kaotic, I presume you did the whole coil resistance test, etc?

What are the symptoms of coils beggining to fail? Breakup or misfire?

All FC coils are the same, between T2 and N/A cars.. just to let you know.

horrible breakup with any boost at all....at least in my case

My engine is cutting out when I hit bumps after it warms up. I noticed that when this happens clouds of fuel where dumping out the exhaust, so I knew it was ignition related rather than fuel. So after making sure everything electrical was still connected correctly and tightly, I began tapping different parts with a hammer to see what effect, and when I tap the coil pack the motor stumbles and almost dies, everytime. This has been an intermittent issue I have been having for a while, and recently it has made the car almost undrivable.

Thanks for the input guys.

Well that could be any number of things. Bad connect, wire break, etc. You need to pull them out and test them per the FSM procedure to know the coils themselves are bad.

You'll be fine with stock coils. I recommend replacing the ignition wiring harness as well, ray at malloy sells brand new ones for around $50.

The only real reason that I am aware of to run the FC leading coil is b/c of the jacobs rotary pro pack amplifier which has been known to cook stock FD coils. The FC coil stands up to the amplifier and will last in that capacity.

Just FYI, the FC oil is not a direct plug in application. You'll need to do some cutting and soldering.

The harness was replaced about 3 years ago, a visual check shows it to be in great shape still. I already verified all wires are hooked up properly and tightly with no breaks or other defects. Of course I will properly test the coils once they are removed, however I will replace them even if found to be in good working order. I am not replacing them with the stock coils as they are ungodly expensive new and there are no used ones in my area. I have local access to both T2 and RE coil packs. I understand the harness will need to be lengthened and modified to fit. I have been meaning to get those coils out from under the manifold for a while, and now looks like a good time. My question is not whats wrong with my car, but whether T2 or RE coils would be a better choice. Any additional info on this question would be appreciated. Thanks for the input

I bet you a virtual 20 dollar bill it's not the coils.

Kaotic Dan

How come your so confident you can diagnose my problem over the internet with only a limited knowledge of the situation? I will let you know when i'm done and send you my paypal for those virtual bucks. Thanks again.

clayne

Because it's damn rare that the coil packs EVER fail. Most of the time it's never the coils themselves unless you've modded the ignition system.

bs....mine went out at 60k miles, and I've talked to several people on here with a similar experience

clayne

"Most of the time it's never the coils themselves unless you've modded the ignition system."

It isn't bs dude. Out of the problems seen and causes of such, the coils are about a 1% contender. And 60k? That's an exception rather than any kind of normal failure.

Kaotic Dan

Well I guess I gotta come on here and eat my own words! I removed the coils for testing and found the problem. There are two ground wires from the main harness that ground under the coils, and they were both damaged. Over bumps the coil pack would move causeing them to lose the ground and the engine would cut out. After repairing and regrounding them the problem has been solved.

Virtual $20 has been sent ;-)

No need man, just glad you got the problem fixed.
