Coil on plug

['87 Turbo "T"]

Hey everyone. Being that it's almost 2026 is there someone that offers a coil on plug set-up?

I know Bailey offers a harness(not sure about brackets) for the TR6 & Cruz offers brackets, wires etc. I've read here Hartline used to offer some things.

However is there anyone out there offering a coil on plug set-up's for our Buicks. Any ideas or links would be appreciated. Thanks!

You can run coil on plug with the ECUGN and this harness: Coil Near Plug Adapter Harness - LS Coils-4004

Well dammit! I’m running the MS3. I may have lead on a harness there though.

Not looking to put the coils on the valve covers so this might be a piece by piece plan. I know I can get coils locally. Just need harness, brackets, & wires.

Any way to set coils back by stock ignition location?

Boost Crew Motorsports makes a plate and spacer system that stacks the LS coils where the stock ignition goes, been running it for several years now.

Very cool! I didn’t see it on their page. I will call them this week.

Thanks! I can start laying some groundwork to see how I can make a set-up work for me.

These cars have ECUGN set ups. IGN1A Coil brackets are from Bison and have some spacers added for positioning.
The ECUGN COP harness will not work with an MS3. The MS3 is not set up with the extra connector on side of the case.
With an MS3 you would need to use a TR6 for COP. Just a matter of placement of the various items.
