Where can I get a 5 bolt turbo gasket

Hey guys, I just need the gasket. Any one know?

I know JGS carries the flanges you can try and contact them, Im pretty sure they can help you out.

So long as the flange surface is true (flat), no gasket is the best option. A steel to steel perfectly flat seal is the best.

why is that? im not disagreeing but just curious

JGS sells the exhaust gasket maker. Works great

If both flange surfaces are true, there's no need for a gasket. An exhaust gasket is designed to overcome deformed surfaces with pits, curves, etc. As we all know, an exhaust gasket cannot forever withstand the tremendous heat cycles it will endure at the engine/manifold mating surface. The heat cycles at the turbine/downpipe surface are many times more drastic, in terms of temperature differential AND peak temperature. It WILL eventually deteriorate and leak, sometimes much sooner than we want.

If you eliminate the gasket altogether, it's highly unlikely you'll blow out a 3/8" steel flange, or big fat turbine housing, and you won't see it deteriorate much. An air-tight metal-to-metal seal is the best. It's a great way to minimize the weak links in the exhaust system.

However, if the surfaces are not true, a gasket would certainly be in order, along with a shot or two of copper gasket spray on each side and each surface. It's good stuff.
