Turbo inlet manifold Vs N/A inlet manifold..
Turbo Mini Forums

I am looking into making an exhaust manifold and find that the N/A inlet manifold makes it MUCH easier esp. in the area if the centre port. So what's the thoughts out there? any reason not to use a N/A manifold?

IIRC the "turbo" inlet manifold creates more turbulence than the N/A manifold which helps to keep the air & fuel mixed. I believe on highly polished tubular manifolds there is a tendency for the fuel to be pushed to the sides of the manifold in turbo applications. That said a lot of people here use N/A inlet manifolds and the Mirage kit is designed to use one.

ive used the mg metro n/a manifold on mine

OK thanks,

I must have missed that one on my search, so Metro inlet manifold it is, makes the exhaust manifold much easier to fit.

When boosted....n/a flow figures can nearly be thrown out the window though.

Something that might seem very restrictive in a n/a setup, can work just as good as a free flowing setup when boosted.
