Honing out a turbo

[WidebodyWoody]

Does anyone know a good way to hone out a turbo housing for a home job hi-flow? I have a spare turbo that I have pulled apart and want to try and quick hi-flow.

Just the entry and exit ports... Remove the sharp edges and clean out the
insides... Don't touch the inside near the compressor or turbine wheels
or you'll destroy the turbo... Just near where the gases go in and come out.

Basically port matching is the idea... You'll need to speak to a turbo specialist to know more about it than that.

I don't think it will do much however, without significant modification to the
inlet and egress on anything that attaches to the turbo as well.

You get better results from polishing the outside... It doesn't work any
better but it makes your engine look like it's been modded.

porting mitsu exhaust components improves your performance significantly. There are lots of testimonials to support this, for the 2.6 and 2.0 dohc.
With hi flowing wheels you're gonna need to port your wastegate opening to deal with boost creep
Some even install bigger flapper
