firewall upgrades?

G Guest
I have my engine and ZF out of my car. The gas tank is at the shop getting "renu" done to it. In the meantime, I was crawling around in the engine bay last night, and wondering if there were any firewall mods that can be done at this time? Is there any benefit to the "stainless" besides appearance? I'm not to concerned with looks right now. I would rather have the car properly sound and safe before I worry about cosmetics. Although, I'm aware that now is the time to do things because the engine being out of the way. Besides getting small amounts of surface rust off and putting some high temp primer of some sort what else can be done. I know most heat enters through the coolant pipes from underneath. Also, any suggestions to clean up the clutter where the coil and voltage regulator are located? (Aftermarket kits from the vendors) Or just tackle it yourself and do what you can. I work with wire all day for a living so I'm not too worried about the difficulty level. Thanks for any advice that is given.

I would suggest that you consider sound and heat insulation at this time, a good foam board heat/sound insulator on the firewall combined with an Alumn.sheild on the engine side does wonders for your comfort. My Pantera was done in this manner and I'm very happy with it, no heat or excessive noise enters the cabin.

I went with the polished stainless steel, I put it over some aluminum backed heat/ sound insulation then covered the passenger side of the firewall with the same stuff under the fibreglass panel. I also glued it to the hatch that covers the front of the engine. Huge difference (improvement) in sound and temp insulation.

As to the stuff on the firewall, I bolted the relay and 2 coils to the bracket and I have 2 MSD boxes screwed to the firewall as I plan on making my ignition system redundant so that if (when) one fails I flip a switch and the other one comes into play.

By the way, the firewall job is a pain. It would definitely be helpful to have a helper because it will take several times in and out of the car to trim it to fit, cut a/c line holes etc. Put duct tape all around the edges to protect your hands & the finish in your engine bay. It looks great when it is done and I believe worth the effort.

A SS panel cleans up the engine-bay appearance, adds a tiny bit of heat and sound-proofing by itself, and being shiny, makes changing the fuel pump much easier to do as the area becomes more visible. On the downside, it adds weight, is difficult to do correctly even with the entire powertrain and gas tank removed, and its one more thing to constantly keep clean which is very difficult due to its location.
