Hey everybody, just need a little advice. I'm doing a custom turbo project and I was wondering what would be something good to use for gasket material between turbo-downpipe and turbo-exhaust manifold. I've been looking for like copper sheet metal but haven't had any luck. Any suggestions are welcome. Thanks!

 

if your downpipe plate is milled flat it wont leak.

u can buy copper sheet metal, but its $$..

 

You dont need a gasket, just run metal to metal, downpipe flange to turbo. I dont know of any thing that will hold up to the heat.

 

Just go to a scrap metal yard. The one near me has rolls of copper and stainless for like $8 a foot. Just cut it to the size you need.

 

Thanks guys. I'll probably get the flanges milled then, one is a little wavy from the grinder. My turbo is a IHI RHB5, its going in a 95 neon dohc. I've heard they're fast spooling turbos so it should work good for what I want it for (street). I had to relocate the battery to the trunk, if any of you own a neon you know that its tighter than a gnat's under the hood stock. I should hopefully be done with installing it this weekend. thanks again for the help.

 

i used this felpro exhaust gasket material on mine. it was like $15 for like this huge 2 square foot piece @ autozone. i just made my own gasket out of it.. was a bitch to cut b/c its metal. i used a dremel to cut it.

 

that high temp felpro burns up in like 10 min..

 

sounds like a waste of $15 to me

 

use a gasket.

you can go to any engine rebuilding shop and ask for high temp gasket material, they will cut you a big square of metal gasket material with holes. cut this out however you want, even a nice shap pair of sissors will do the trick, and use that as your gasket.
it holds an excellent seal, and it will never burn off.

 

grarhite gaskets are the only gaskets that I've seen hold turbo kinda heat..
