Hey guys, when I first did my 3800sc swap I ripped out all the insulation. Needless to say I didn't like the heat/noise etc... Now with the swap dropped out and my turbo plans, I'd like to pretty much wrap the whole engine bay. I know the Lowes stuff works for sound, but what is good for heat? Also I like the asthetic appeal too. Thanks!
The next time my engine comes out that's what i'm doing. It's not cheep as you need to buy/rent a gun too but i don't think there's anything that compares to it.

You can paint it after it dries.
Or, cut a big piece of aluminum or steel sheet (or diamondplate if you wish), to fit the firewall area, similar to what fieroguru did for his swap here: //www.fiero.nl/forum/F.../000123-15.html#p571
You can spray Lizard Skin, or other spray/brush-on insulation/deadener on the back of it, and on the firewall itself that the panel will cover. It'll look much better, and should provide plenty of insulation.
Now what I used on the interior was this which works as good, if not better than dynamat: Much less expensive for the same results, but I have never tried it in the engine bay.

I have used a product from Second Skin Audio (Damplifier Pro) on the interior of my car and it would likely work in the engine compartment also. The first set had a silver foil and the second shipment was black foil so you may want to check on what they currently supply.
West Marine Acoustical Foam #216858, it is engine bay insulation for marine applications with inboard engines. It comes in a 54x32 bulk roll with a retail price is 117.99 last time I purchased it... If you only insulate to the double firewall tube, then 1 roll will cover 2 firewalls. http://www.westmarine.com/w...rorView#.UlcvBhBWmJs

Doing the same thing myself. Got a similar brand at Home Depot for $16 a roll. Sticks like MAD.
With the rolls of insulation, will it have a proper cabin insulating effect if placed on the interior? The backside of the firewall? If my point is to keep engine heat out of the cab, but I dont plan to remove my engine or wiring harnesses?

The insulation in the engine bay helps keep the firewall metal from being heated up (my smooth firewall panel will be 150 to 175 degrees after a drive). Putting the insulation inside the car, allows all the metal to heat up and the heat will be transferred to all other connected metal as well. Placing insulation only on the interior helps to some degree, but it won't be as effective as insulation in the engine bay.
Hey guy's sorry for the long awaited reply... I did buy the stuff from West Marine, and I was extremely pleased with it! The roll I received was very high quality, adhered fantastic, and looks exactly how I wanted. Im planning on a top mounted turbo over the transmission so I beefed up that area, I covered both firewalls, heavily covered the drivers side (turbo location) did around the passenger side where the coils would be, and still had extra! Still not finished trimming but you get the idea.. Here are some pictures...

can this stuff go in to a normal 2.8 with engine still in there? I fear starting installing and getting half in and find out I am screwed...
Just use the West marine stuff. And it was very difficult cutting it to fit with the engine out. I think it's impossible to do it with the engine in. Btw... In my garage with a floor jack and hand tools, I can drop the cradle in an hour. It's really not hard at all.
