I'm trying to simplify and tidy up my engine bay. Just wondering of anyone has any info on coil pack and battery relocation. This is on a right hand drive s4 turbo.

Sorry if its already covered, just couldn't find any fc specific info on the search

Battery relocation is fairly common, this is how I did it.

Moving the coil pack(s) is less frequently mentioned (or done), I did that as well, purely for aesthetics.
The trailing coils are nicely tucked away already, I felt no compulsion to fiddle with them but the leading coils offended my sensibilities with the (seemingly) random placement and resulting long plug wires, so they did get moved.
This particular placement is only possible after deletion of AC and PS and looks like so...




The coils are mounted in preexisting holes in the strut tower (conveniently prethreaded- thank you, Mazda!) which almost exactly duplicate the coil bracket holes...I only enlarged the bracket holes slightly to make it work.
Underneath the coil pack is the 1/4" aluminum plate I made as a master cylinder brace.
The relocation requires delooming the coil wiring from the main harness but no other changes at all.
I custom made the necessary short plug leads but you could probably find suitable ones with the cooperation of a friendly parts store.

I've seen pics of the coils (both sets) moved into the cabin, leaving only the plug wires visible in the bay but that would be better suited to a stripped track car that has a lot of spare room behind the dash.

That does have a very tidy look to it, Clokker. Sort of looks like it was meant to be that way. But doesn't it make it harder to access your spark plugs?

Not at all, access is totally clear.

Awesome thanks for the pics. I still have PS but being RHD I should have a little more space to play with, but something similar to what you have will be good. Cheers

Not to thread jack but did you move your overflow bottle too? How did that work?

Yes, the recovery tank has been relocated (and actually, replaced altogether with one from a different car)...it works fine.
The cooling system doesn't know or care where the tank is located.

Instead of making another thread I thought I'd post here.

Im in the process of removing emissions. Just wondering if anyone can tell me where this fuel line goes?

"FUEL LINES - you will be running the fuel lines along a longer run. Run a line from the fuel filter to the primary fuel rail, and run a line from the secondary fuel rail to the metal nipple that heads back to the tank. Use ONLY fuel injection rated hose, 5/16" ID, and you need about 6 feet worth to do the job. Zip tie the hoses together and keep it tidy - you don't want them rubbing against things or the like."

I dont have enough space to jack it up at the moment and cant see where this nipple is. Does it hug the chassis near the fuel filter?

Yes.

Cool thanks.
Another thing I need help with is, do I just cap the fuel pressure regulator vac lines?

Also with the PVC system, do I have to vent both exits? One under the oil filler and the one where the neck joins the block. Can I plug the one on the neck and put a filter on the block?

Dunno, my motor is stock.
