I got a mess of coil-on-plug coils GM or chrysler (not sure right now) I was wonderin if their was a way to take off my stock coil pack and wire these up? From what i understand 2 cylinders are fired at a time so I could hook the same power and signal to two of the coils the other signal to the other two.
ANY info would be appreciated

What is wrong with your OEM coils?

I agree. Maybe you should start with a Coil on Plug Why To, before you ask for the How to.

Brad

There's a VFAQ somewhere floating around with details on how to do exactly what you're talking about. wish I had a link for you.

sounds interesting but whats the point?

A COP ignition is only necessary for really high performance race engines or high compression street cars ( vehicles like the Corvette and other new cars are starting to use COP ignition ) to deliver the required voltage to fire the plug in a high boost or compression enviroment. The more an engine compresses the intake air, the more difficult it is for a spark to jump the gap on a spark plug. Newer engines are now running much higher compression ratios than they used to which is why we are seeing more COP ignitions from the factory.

4 coils is better than 2 coils. Period.

Buschur Racing sells a COP ignition for the 4G63T priced around 500$. JDMawd has some pics in his gallery of them installed.

I would just look into something like this instead.

So you are saying if I took 4 coils off an 125cc dirtbike, and tried to use them on my DSM, they'd be better? They are designed for a magneto CDI, turns ratios are off, impedance is way lower than stock DSM, magnetic storage capacity is slim. But 4 is better than 2 right?

NO you say? Ooooh wait, it depends on the application doesn't it? So 4 coils, if properly matched and properly driven, would be better than 2? But 4 coils that are just thrown together, and run off of 2 drivers, could quite possibly not even run, and likely NOT be an improvement over stock? Ooooh, I get it now, thanks for explaining that.

If there was any doubt about you being completely clueless regarding ignitions(and I had no doubt about it, but others may have), then posting the URL for directShit certainly cleared that up.

That is just in essence a spacer over the plug, it makes the charge jump across a gap before getting to the plug. Your coil is only going to produce enough voltage to jump the spark plug gap, those things just make it harder. It will definetly increase voltage at the plug, how much of an effect that has I have no idea, never tried any of those things.

did anyone else notice that they used a diff type of spark plug for the befor and after pic

The directshit are capacitors in series with the plug, not spacers over the plug. They are effectively the same thing as Nology wires.

The voltage at the plug is a function of the plug gap and what is in the gap, adding a cap across it serves primarily to retard your timing.

FYI Brad:

Alcohol and internet forums. They don't mix.
( Did you get that keg fridge yet? )

NDgsx: Thanks for the serious reply. I did not know that about the Direct Hits and will stay away from them.

Just for those of you who might be a little confused about earlier:

I do not or have not made the claim that I am an expert on COP ignitions.

Hey Groomz-

You had better STFU and back off, before you get yourself into any more trouble than you are already in. Stop shoveling, or you're never going to be able to get out.

Edit: Well, your editied reply certainly is better. You learn fast!

On the topic-

There was a VFAQ that Hal Landry wrote (and maybe more, that is the mainone that I know of) which described how to mount 4 COP's on a 4G63. However, a few people tried it out and in the end the general concensus seemed to be that it wasn't worth the time and money. I'm not going to pretend I remember why, but people went back to stock and that was that.

A well built and designed system will be an improvement, but that means probably not using a pile of parts you have around.

WOW such hostility!!!

The buschur COP setup that I believe utilizes 300M coils. May not be needed for most setups, Hell i probably don't NEED it for mine. However the idle and smoothness during normal driving and under boost is very noticeable and in my opinion with the price.

To each his own I guess.

I'm feeling the DSM love.

You should probably have put that right in front of your thorough(ly wrong) analysis of why manufacturers switch to COP,and absolute(ly incorrect) statements about it. Stronger spark is not the reason. 4 coils are not always better than 2. People think COP is some sort of holy grail, its just a different place to mount coils.

Brad

You guys should check out the new COP buschur is doing for the EVO its pretty bad ass.

If you pulled off your old ignition with coils that have seen lots of miles, old plug wires, and put this in(especially if you did new plugs at the same time), you would see this type of improvement. You would also see it if you had just replaced the worn out stuff with OEM.

I haven't measured the spark output of the 300M coils, so I can't say its not making more than ours. But I can say that making the 100mJ ours makes at idle is more than good enough for a smooth idle etc. as long as your ignition components aren't dying.

I was trying to find pics of the complete Buschur setup, and found your post on the install. I guess you just put these on a month ago? And they use the stock power transistor, wiring, etc? They just wire in in place of the old coil?

Brad

the coils that are sold at buschur are NOT 300m coils.. and the coils he has wont work.. i did the same setup that hal did.. bought the 4 300m coils, built the harness and put them on my 90 awd.. it didnt work because the our coil pack actually fire 2 times per rotation ( waste spark system) where as the 300m coils arent setup for that .. i called buschur and talked to tim and asked him about the kit they make since he builds it .. and i was told that coils he uses ARENT 300m coils.. as far as i know hal never got his to work correctly .. i havent watched the thread in 4 months or so.. but i had the same coils he did, built the same harness according to his instructions on the thread and otehr people did to and none of us got them to work.. but hey things might have changed in 4 months.. i have since sold the coils and harness i built.. and went back to the stock ones... they are just as good. i also caleld don polk at polk performance and they said they have ahd more problems w/ those kits and people trying to build them and just messing other things up and bringing thier cars to don and then they would just rip all the coil on plug crap off and use stock again... if you have the $500 to blow on the coils great do it they look good.. BUT if you have a after market intake manifold like me you HAVE TO have a different coil setup because the aftermarket intake has no place to install the stock coils... and the extreme 4 coil set up is good to.....just my 2 cents ...Steven

You make to many assumptions, what makes you assume my coil was old? In fact i had to purchase a new coil when i purchased my car 2 years ago. just before i got the COP from buschur i had just replaced the plugs and wires when i installed the new turbo setup.

that is correct you remove the plug from the stock coil and splice the wires from the plug. for the 1-3 trigger(white) 2-4 trigger(red) and 12v power(black). To the red purple and orange from the buschur COP setup. The system does not come with a plug just the 3 exposed wires from his main harness. with instruction to match up the color codes.

hey jdm-how about some part numbers for those coils.they had to come from somewhere.

All i know is they come from buschur. i dont see any markings or numbers on them.

I'm going to say that this isn't right. Our cars only fire once per rotation (waste spark) instead of once per TWO rotations like you would with COP ignitions.

Second of all, the fact that the coil has to fire once or twice per two revolution has no fact in the matter of whether or not they are going to work. The only problem I can forsee is that if the 300M coils wouldn't charge fast enough, they would have trouble firing twice as often, especially at the higher rpms in a DSM application.

read the 3rd and 4th pargraphs under that diagram on that link up there........mine NEVER worked.. not even a missfire.. i built the harness just like hal did and he ended up w/ the same thing .. the thread that all this started on was over 4 pages long and none of us EVER got them to run.. if anyone out there does happen to get it to work.. let me know.. cause i can get 300m coils ALLLLLL day and in case you didnt know this you CAN buy just the coils at parts stores, they carry them i believe they were $25-$30 a piece maybe.. but hey you get them from an Oriely's and they have a lifetime waranty on them...
