Hi everyone,

I have recently had the trubo flange on my standard gtr manifolds ported/enlarged so they look pretty good with a gasket on top.

But when I put the gasket over my trubo's flange you can see the turbo flange excess material over hanging the flange by around 1cm / 1/2 an inch.

Should the turbo house manifold be ported as well or is the most common thing to do to just put them on as is? I am just worried about stuffing up the turbine housing.

port em...make the transition from the manifold to the turbine wheel as smooth as possible.

I had a thread about porting the turbo side of the exhaust manifolds and was going to have a crack at porting it myself. But if it's advisable to have the turbo ported too might get a pro to do it.

Anyone know who can do this Melbourne way.
