Well, just made my life easier. Found a junk 16g on ebay. Won the auction for 80 shipped. Looks like a 420 serial number, which should be a 68mm exducer. Haha, no machining needed. Just a wheel and rebuild kit now.

that's the exact turbo my Evolution VR-4 had from factory, and all I did was fit a 20G wheel with the matched housing and had it balanced with a 7deg cut on the turbine wheel.

Been thinking about clipping the turbing as well. Justin on tooners has made comments that it doesn't really help that much, is this true? I know spool is slowed, but no concern there.

Even EvoX's in Japan clip it with a 20G (?) compressor...

I didn't notice much difference in spool to be honest, perhaps 100-300rpms depending on which gear you're in. But the extra mid-range and top end punch were well worth it!

Not sure on clipping anymore. Found a 9 blade td05 turbine wheel no. I think that would outflow a clipped wheel. Been researching and running math on possibly opening up the turbine housing and changing the A/R ratio some to allow more flow.

The exhaust housing on chinabay 16G are bigger than a MHI unit and flow better. A/R is around 0.7 if memory serves me right.
It's almost a direct swap. The guide pin needs to be filed thinner. That's it. Bolts right up.
