turbo exhaust manifold - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

now ive been wondering this as of late with the new maximas and some of the later model quests and other car makes they have a plastic intake plenum. now when you think abou tthis plastic would be more smoother compared to metal. (in the case the plastic is smooth vs stock non ported manifolds) it would also be lighter.

my question is can this be done on an exhaust turbo manifold? would it be any better besides that it would be lighter and more free flowing? would the pressure in a turbo system not allow you to use this?

anyone got insights or anything to add?

The plastic would melt do to high temperatures.  It might crack cuz of pressure too.

it would have to be some sort of hybrid material.. like kevlar, and aluminum..  (don't even know if thats possible.  I'm sure they don't use that stuff do to reliability, and expense to make it.  I have never heard of plastic that had a higher melting point that iron or steel which is what your exhaust manifolds are made of.

I was pokin around under the hood of a friend's '89 Supra.  It has a radiator hose looking material feeding the compressed air to the I/C and from there to the throttle body.
I don't know the benefits of it, except cost.
