Any need to port the IWG of a high boost 2560?
Planning to eventually run my 2560R at 18.5psi. Been reading about IWG creeping and porting, and I'm itching to just hit it with my dremel.
So I have any reason to actually do that? Should I? |
It would be a good idea! I know Doppelganger had some issues with his 2560 running 12psi. dont quote me on that though, but Im sure that porting the IWG hole fixed what problems he was having.

Actually, switching to a later designed unit is what fixed his problem.
But really, if I'm not going to be able to quote you on it, I'd like to see what someone a little more confident has to say. :) |

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. |
I didn't read anything about that in his thread, not that I remember. Just a newer unit.

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; |

Here is a how to for the DSM guys just to give you an idea!
http://www.dsmtuners.com/forums/arti...p-porting.html and hang on im searching for one that has to do with a Garrett! |
Got a compressor, no air dremel though. Should I get this?

Also, I can figure it out from that guide. Make sure it opens 90 degrees, smooth out the transition, open up the hole. The flapper cover is much bigger than the hole on one side, I should be able to open up the hole quite a bit from the look of it!

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: |
Found it, just posted. :D

Ok, I just watched that video! Pretty neat! What's the name of that grindy bit he was using? That just ate through the metal! Intense! And what're the name of the circle sanders? What's the name of that flat sander thing at the end? I'm new to air grinding tools. >.>

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. |
haha, you can mod the HF die grinders to get more ummphhh out of em! :lol:
