Exhaust Manifold Gaskets

[gonzoninja]

When I fitted the single turbo to my FD I fitted the gasket for the exhaust manifold (the bit that goes next to the block and that the turbo is fitted onto) that came with the kit, which was made out of normal gasket material.

I\'m pretty sure this is blowing now as the turbo seems to be slow to make boost lower down (it is a GT35R so should spool fine) and then has no problem over 0.4 bar all the way upto 0.8 spooling like a ninja.

Anyway the standard mazda FD ones are metal, right? Is this the best material? I was thinking of PTFE but that has a melting point of 300 odd Deg C and I think a rotary can kick out up to 800 Deg C, therfore way in excess of what it can handle, I guess, unless it is 10mm thick or something...
