Hello everyone! I own a 1985 Pontiac Fiero GT with a 2.8L V6. I've recently managed to improve its performance and reliability, and now I'm looking for advice or assistance on sprucing up the engine bay. My goal is to tidy up all the wiring and remove any unnecessary components or parts that don't help the car run well and go as fast as the stock engine will allow—except for the air conditioning—I want to give it an almost show car quality where it looks like the engine is just sitting in the engine bay not connected to anything.

Any tips on where to tuck wires, or what parts I can remove/move to different spots would be very much appreciated.

There's a few things you can do. A lot of people remove the (trashed) insulation around the engine bay and replace it with a newer matting. It tends to fall apart and look nasty, so that's one thing. There's also a few bits in the engine bay that are still left over from the recall, so you can remove those (the tube that runs along the back-wall).

Mostly though, a lot of that stuff is unfortunately required... but there are some things you can get rid of. The cooling tubes that connect to the throttle body... personally, I think they look cool, so I keep them, but a lot of people remove them.

There's also the EGR valve and EGR tube. The ECM is designed to expect the EGR, and is pre-programmed to reduce (EDIT, increases) fuel when the EGR is engaged... it also improves fuel economy. However, if you reprogram the ECM or upgrade to a continuous self-learning system, you can eliminate the EGR. Mostly though, there's not a whole lot that you can remove, unfortunately. My best advice is to make everything as clean as possible... and then you don't really notice the nasty...

Clean, clean and clean some more.

It really depend on how much time, effort & $$$ you want to put into it.

Remove the insulation, add it back under the carpet inside.
Remove all unused tabs along the firewall, or install a smooth firewall panel.
Rework harnesses and hoses to route where they are more hidden, including changing where they pass through the engine bay.
And much, much more!

Here is what you can get when taken to the extreme:
