pm him, duh

 

So I can use my stock copper gasket on my HF manifold when I do the turbo? This would just be another thing I don't have to worry about anymore ... also am I going to need to gasket my manifold to adaptor and adaptor to exaust housing?

 

On all my HF/STD turbo setups I always used the factory HF manifold gasket and it never leaked.

 

I would suggest not using copper manifold gakets. It is a heat conductor which will tend to conduct the heat from your manifold to your head (engine head). Naturally the coolant will soak up the heat, but it also cools the manifold, which will cool the exhaust which then makes your turbo less efficient and increases turbo lag. Heat is normally the enemy, but you need as much heat as the rest of the engine will take to go through the compressor. Use the layered stainless OEM Honda gaskets (crimped around the ports) if possible. Stainless does not conduct heat as well. You should use gaskets for all connections if available. Some builders use the hi temp copper spray on gasket sealer (rated for about 500 deg f made by permatex) for thier gaskets and/or gasketless conections. I know that most turbo applications will see in excess of 1200 deg, but the engine builders still use this sealer. I know Mopar does not use gaskets at the turbo.

 

I think he meant HF Mani --> adapter
