High Flow Machining question

[Bass Junky]

I'm about to get my turbo high flowed, and I have been told that it can be a good idea to open up the waste gate hole a bit for better boost control up high.

So my question is.......

How much by?

Do I simply bore out the existing hole to a larger size and make up a new wastegate cap to suit?

Do I bore it out in the same plane at the same angle or do I change the angle to sim more towards the gases comign from the manifold?

Cheers

Pete, give Brett a call at GCG and ask him what options are available. He has done everything you can think of with Nissan Turbos. He knows what he's talking about too.
