Yet again, we revisit the CIVIC EXTERNAL COIL

Ok, so I'm searching for all this info that I just love to find. I can't seem to find the answer I'm looking for.

Accepted premise:

A. The accords had external coils. The preludes had external coils

B. The early 90s prelude distributor cap fits perfectly onto my d-series civic dizzy

C. The cars with factory external coils had all the necessary wiring and connectors for said coils.

So, could I not just put a factory prelude cap on my civic, cut a dizzy side coil harness off a spare dizzy, take a prelude or accord coil & harness & bracket, wire the connectors together, and have a factory HONDA external coil system?

So instead of paying 500 bones for a MSD setup that is known to have/cause issues, I could run honda oem parts, AND have the added benefit of a cool coil/nonoverheating coil. For something like 100 dollars (if I'm just really unlucky)

If this has been covered, I apologize. I've searched and cannot find the answer.

I think its partially BS. A coil may be CAPABLE of 20% more, but it wont necessarily just give more output. Electricity is lazy and that "extra" % will only be use under the hardest of conditions.

well, tapping wires....... i don't like that, looks like shit. If I was going to do that, it would for sure be making a harness to plug into the vehicle side of the coil harness. Also, again, msd accel, same crap. It can be "higher output" than OEM but Honda knows what they are doing. OEM coil is going to work better, more reliably, and longer than any aftermarket counterparts. I just wanna know for definite if I could do that. Use all OEM parts to change from internal to external.

Because, I'm sitting here, wondering why the hell I should pay 300 dollars for something aftermarket that is known to have issues, when I can OEM it up, for cheaper, and have reliable, long lasting parts to work with.

Looks like shit? It depends on your handy work. The wire connections are made in the distributor and are hidden anyway.

I don't remember the car I pulled the cap off. Only that it was a prelude, with that one ugly looking style coil.....if that helps. lol

My distributor is the OEM one for the 92-95 civic d15. (not sure it makes a difference, but its 5spd 4dr) I do remember seeing the cap and thinking, ooooooo, I wonder if that would work? I got it from the scrap yard for like 2 bux and jus did a test fit, and the holes r the same, and it had a pickup for external.

Doing it that way, you wouldn't have to cut the dizzy, or every new cap u get, or splice any wires (except the building of the harness the first time, after that plug and play), or pay outrageous amounts for a new MSD or ACCEL (Pretty sure both american, which is why they suck on jap cars) cap and rotor every time. Just buy OEM parts from honda or autozone or oriellys.

I'll try to find the cap here this month and actually try to do it. I'm hoping to have the car back up bfore december. Bike, 40 degree air @ 70mph, I think I'm good....I want heater back. If it works I'll post it up here in a new post w/ Pics and all. Give people a better, cheaper alternative than performance parts for their piece of mind.

I thought the exact same thing when I was doing my h series swap it seems like this would be more popular with d and b series guys.

There was a reason for the h and f series to go external( some have internal higher end have external. ), most of the places I was looking said the external help with high rpm a good amount, and the odd h/f series guys do it.

Also I am fairly certianall the distributer cap bolt patterns are the same obd1-2

Sorry for taking so long, internet went out. To answer the question as to why, it's only a personal preference kinda thing. The OEM dizzy on the civics don't seem to fail at a regular enough rate to really worry about it, honestly. I just figured, get the coil out, reduce some of the heat that ends up tearing up the insides when they do fail. Maybe it's not enough to worry about it, maybe it is, I'm not 100%. I just wanna do it to do it. Make it my own. With OEM parts.....lol
