Flange to Turbo GASKET???

[4g63telantra]

On the Exhaust side of the turbo where I start the downpipe, should I be running a gasket or just high heat silcone? Its a T3 5-bolt flange by the way.

I'd imagine you need a gasket. The temperatures there are like 1500F which is frikkin hot. I don't know how high you can go with silicone, but it's probably like 700F.

I would also definatly use a gasket.

3rd vote for using a Gasket

I'll make another vote for the gasket.

My setup, HRC Super16, didn't come with a gasket between the turbo and O2 housing and they said one wasn't required. However, after the install I had a leak there but never thought about using high temp silicone because as stated, it gets pretty damn hot there.

Although I would imagine it's cooler than 1500 degrees, I would agree that it's probably hotter than the high temp could handle.
