Default Are there issues with 2004 2.5RS Plastic Manifold handling boost?

A member swapped the metal manifold on his EJ22E to this to drop temps by 16% in one occasion: http://www.rs25.com/forums/f5/2880156-post56.html. But this build is only N/A, for those with a 2004 2.5RS and a turbokit, was the plastic manifold an issue at all for boost?

I've got a boosted 04. I'm only running 6-8 psi but I've had no issues.
