Back when I first got my rx7 I remember coming across a post on every delete , I think it was in aaroncake.com but I can't seem to find it now, I'm just trying to clean up my engine bay, if you can't seem to find it either can someone link me to a post that shows how to delete everything that's not really needed in the engine bay

 

Your question is very vague as You can pretty well delete Everything in the bay..Including the engine itself.I did..
You can wire tuck,emissions delete,OMP delete(s4 only),Air box delete..
Bubba Gump Shrimp....

 

If you're referring to "emissions", the search term you want to use is rats nest. You can find a detailed rats nest removal for every series and model engine on Rotary Resurrection's tech site.

 

I used Rotary Resurrection's article for mine, very easy to follow! No more rats nest.

 

You can do a pretty extensive cleanup of the bay without actually deleting anything.

 

On the FC it is pretty easy to tuck the whole front harness out of sight in the front fenderwells and bumper- really cleans up the look of it.

If you are running aftermarket ECU with MAP tuning and your own harness you can get it really clean looking as the stock engine harness is kind of an eye-sore.

I never went so far as to really clean up the driver's side by the firewall where you have wiring harnesses entering the bay, coils, fuel, oil line, spark plug wires, etc. That would take some work.
