Are you sure there is supposed to be a gasket between turbo and manifold? Head to manifold, yes. If there is one at the turbo inlet or outlet, it will be embossed stainless steel. Any sort of paper/composite gasket will last not at all.

Thanks for the input and the laughs, guys.

As for whether or not there should be a gasket... Well, Toyota used one on the car this turbo originally came on, so i'd assume there should be one?

I'll give it a shot without a gasket and see where that gets me. I think i may have just put a gasket in there because i spent hours tracking down all my exhaust leaks, and i was sick of it, so i just threw something in there. I am not exaggerating when i say that this car was probably losing the equivalent of 80-100hp through various exhaust leaks before i tore it down.

Trying without a gasket just costs time, right?

As for the stove glue gasket gunk, a few of the local drifters use it on their cars, and they don't have issues with it, and i think they're under more stress than my car.

I will try the copper idea before i go to that, though.

Thanks again!

If the copper doesn't melt, it seems like a great compromise.

What thickness am i looking for in terms of copper? Hobby Lobby seems to have 0.025" thickness.

I know more then a few guys that use the dark brown grease used in u-joints to butter the flanges. Smokes like heck and smells nasty 1st time but seals up tight. I'm told as it cooks it turns to carbon and locks in place.

Picked up a sheet of copper at Hobby Lobby in 0.025" thickness. Was 50% off! So... got it for about 4 bucks. There's enough there to make at least 3 gaskets, so i'm set.

Thanks guys!

if you are worried about thickness start a trend and make a ML copper gasket

I don't think i've got room for a double layer of this stuff. I've got some pretty rigid clearance needs because of my exhaust/wastgegate setup. I think a single should be fine, though.
