I'll pick up some blades for my jigsaw and try that next time. I cant imagine, though, that it'll be easy keeping the thin sheet of alum. steady while hitting it with the jig saw.

What about putting the saw upside down in my vice? That is something I think i'm going to have to try. I really do not want to dremel this **** out again.

This tread is not that old so I have to say that I have the FM air box but I made an air filter out of uni foam and a pencil holder!

Great job! A bracer board clamped across an uncut side will help hold the
Al while you cut with the Jigsaw,get a fine tooth blade and go slow.A spraybottle of water mixed with 1 teaspoon each of oil and soap will help cool and Lube blade,make it cut smoother ,faster and last longer.

lol instead of doing that i just built a box around the turbo


I used sheet metal scissors and then just bent the edges to round it off.

haha, very funny you mentioned that! The JB weld lasted about 2 days. Now it is riveted.

Thanks for the tips RG. I'll remember that next time.

The shield isn't currently in my car. I need more 2.5" pipe to redo my turbo inlet to make the shield fit with my new low mount manifold.

I just tried this with my turbo heat shield and I couldn't secure the cardboard well enough for the hood to press on the skewers and not just deform the cardboard base. I gave up, made it big, and cut it to fit.

Update. Hobby lobby shopping list.
Project board header 1.99$ They also have plain cardboard that is the same size for 3X the price and it does not have the purple backing (not pictured here) that seems to add some rigidity to the cardboard.
Stick things 3.47$ I cut these in 1/2 so there was less resistance when in the cardboard and you do not need the full length.
