Here's an easy way to remove the diffuser part of an N/A sleeve
Sorry if someone already had this idea; I really don't have time to search through 100's of posts to see if it is.
From what I've read, there seems to be much confusion reguarding how to "grind" these out. Well, GRIND is too literal, and if followed to the point, it'll cost you a bunch of bits/stones/sandpaper dowels. I found a WAAAY simpler way to do this if you're cheap like me, and don't want to purchase T-II sleeves. I mean, why pay for what can be had with a little work? :biggrin: 1 - Remove the sleeve from the housing (2 pins, one on each side of the housing; use a screw extractor and slide-hammer) 2 - lay sleeve face-down on hard surface (the big hole goes down) 3 - take a SMALL (1/2") cold-chisel and place it where the diffuser comes from the sleeve (the "root") 4 - Angle the chisel ~30 degreese (towards the roots, of course), and pound away! (tap-WHAM-tap-WHAM) :bash: 5 - use a cut-off tool and chop the "lip" of the sleeve off. (the chunk of metal that's angled upwards) 6 - take a pair of vice-grips and straighten the end of the runner out (the angle portion of what was just cut off) There'll be so little metal left, it's a chinch to grind out with even a dremel and carbide bits! Okay, since the people who are reading this will porbably have ported/lots of porting experience, I also have a question: On a 13b 6-port: On the end housings, the port is divided in 2 by a "bridge" on the rotor side of the housing. What would be the gains (if any) to grinding this flush with the runner, and tapering the port-runner divider at a ~40 degree angle (perpendicular to the port)? Essestially, combine the 5th and 6th ports into one large one (still keeping the ports separated UP TO the port). Anyways, hope this helps. Man, I could just see some people sitting there with a die-grinder, slowly eating away at the hardened stainless diffuser. WHaCKo |

What's the point of this? I heard the diffusers are there just to dampen the exhaust pressure waves and sound :confused:

Ya they do quiet, but they are kinda restrictive and get in the way when porting.
RX7 RAGTOP: come on man, not every one has junk t2 housings laying around and this post was designed to help those people. Also with reguards to combining the ports thats not that big of a deal. My friend did it and his car still idles at the stock range and still makes ok pwr in the lower end. CJG |
