Can T3 gaskets survive increased boost levels?

[IM-32-FK]

hey all,

I’m boosting 12-13 psi on my stock op6 turbo. I replaced my leaking t3 flange gasket with a OEM Nissan gasket but it got my wondering if I should of gone aftermarket gasket instead. I’m talking about the gasket that goes between the exhaust manifold and the turbo compressor housing, the rectangle shaped one.

can the genuine Nissan t3 gaskets take increased pressure levels without giving way?

thanks

Genuine Nissan gaskets are amongst the best out there. Will handle plenty of boosts. Just need to check that the turbo flange bolts are tight every once in a while and it'll last years.

^--- this. The Nissan OEM gasket is a league better than almost any other alternative gasket you can get. Have seen other brands of modded cars opt for the Nissan Gasket over their own OEM one or aftermarket ones.

The studs and nuts that hold on the turbo however are a complete PITA and you will constantly need to check and re-tighten them because this is 90's turbo life.
