You gotta think if your running 15psi on that sucker or more when that waste gate opens your forceing all that pre WG pressure through a 1 in hole (thats not even 1 square inch). That little hole can only flow so much volume of gases through it. Any porting you do to that area is going to help! What are your actual goals on the 2560? depending on how efficient your set up is you can get some where in the 280hp range.

Researched it: https://www.miataturbo.net/showthrea...ighlight=creep
Story: Old CHRA + New housing = Creep
Old CHRA + Old housing = No creep
Old CHRA + Ported new housing = No creep
Been looking up any guides on how to do this porting, how much to take out, how to do it... this cast iron looks like it'll just chew up my stone dremel bits, too. o.o;

Got a compressor, no air dremel though. Should I get this?

and make sure you polish were you gring to cut down on possible cracks from groove line hotspots. Not really perfect but fairly smooth!

I've burnt up wayyyyy too many dremels in the past. Getting an air one would cut down on my long term costs, to be honest.
They didn't touch on making the actual exit hole bigger in that guide, but the Garrett one is much different. I'll need to try to find a Garrett guide on it or something.

Yeah, I figured I would post that one up to get the general idea across. I seen a guide some where a while back. I thought it was on FMs site (maybe BEGi) Im still looking! :lol:

When your grinding with the carbide bit you have to be really carefull, they like to bite into the metal and start bouncing around. You gotta always pay attention to what your doing and keep a tight grip on you die grinder.
