I am relocating my battery to the front under the spare tire. I decided to also relocate the coil packs. They were mounted in the center of the firewall just to the rear of the fuel tank (like this when i bought it). The coils were in the way of the battery cable routing so I removed the coils and need to move them elsewhere. The battery tray (now empty) looks like a potential area to mount the coils. Anyone have suggestions as to where to mount the coils? The plug wires seem to route well to this location.

That is where I mount them in the swaps I do where the battery is mounted up front. U can then route the plug wires where they can not be seen.
Old battery tray is my favourite spot to mount the coils and the PCM on swaps where the battery has been moved. Dan

Thanks for the replies. Anyone have pictures or links to existing pictures from other threads? I am thinking to mount the coil base plate horizontally to the existing battery tray.
I made a 3/16" steel bracket and welded it to the shock tower, I also welded a 3/8 bolt on the underside to run all my grounds to. This left me enough room to mount a Braile battery in the stock location if I wanted to in the future.
Isn't putting the coils where the battery "Was" going to raise hell with them being under the vent? When it rains, they're going to get drowned. I wanted to put mine there, then thought no. Are they "In the way" of the trunk lid or hinge in the stock position ?

I haven't had an issue, and i just did my 1st 2500 mile service, and I know 300-400miles of that was in and down right monsoon, also I to leave it running when I wash the car, but that's just an old habit from my LT-1 vette where washing the engine bay with the engine off was a sure fire way to score a no start when your where done. If the car was to stumble at all while spraying off the pass side vent I would be concerned but all is well.
I mount them away from exhaust heat. The ignition module is not designed to last in the presence of extreme heat, which you would get directly above the exhaust manifold. Rain is not going to hinder the coils, as long as they are in proper order and not arcing....which would be its own separate issue. I mount my coils low to hide the spark plug wires and I've had my coils under water in a flash flood situation. That was 20,000 miles ago and I haven't had an issue then or since then. Dave

That would be a NO....The coil packs are weather packed so getting wet does not hurt them.
What if washing the car and the area/coils get wet and it misses? Coils are mounted on firewall/bulkhead to passenger compartment under the vent on the passenger side.
Mine have been in the stock battery location (battery moved to the front) for about 7 - 8 years, and when it rains here, it POURS. I've had no issues with water causing ignition issues. And I do not shy away from the vents when washing the car or hosing off the engine.
Battery tray mount: . . Auto trans swap mount when no dog-bone is needed and alternator is relocated to low position: . . On my turbo 3800 swap, I have them mounted above the battery tray to make room for the intake piping that passes under them. I have a rubber flap I installed over the top of the coil pack to keep rain and water off them that could pass thru the vent. Never had a problem in this location.

I may move my coils again. For now this is where they are and I've had no issues from the heat.

Also mounted coil pack where the stock battery was and I have been caught in a couple of very severe rain storms. The coil pack apparently has good water resistance but when the car is moving on a highway air moves quickly upward and out of the vents. I believe that this keeps the coil pack somewhat dry when the car is moving.

This is how my coils were done on my 84 SC car. The previous owner put them in this location. I had not previously seen them located like this, but they work fine. Not perfect to hide the wires, but the wires are not the focal point , either. But, perhaps the coils are! There are much cleaner installs, but this is not the worst I've seen.
