A couple things, you might want to consider!
 

Guys,

I just thought that I would tell you guys a little something that might make your rides a little bit faster. A lot of people in my group of enthusiasts (Nissan SR20DE) extrude hone their turbine housings, and have very good results. It seems like many people here have a bad impression of extrude honing, and I concur that often it doesn't do dick to EH the intake manifold, but we often see a decrease of 500-600 RPM in the onset of max boost with a .82 A/R T3/T04E turbo! Considering how big of turbos you guys run, and how much lag a lot of you guys deal with, it is worth a look!
Another thing that we have had success with is aquamist water injection. This is not a crappy, hose water into the intake system, it is high pressure and atomizes the water well. It works great to ward off detonation. Considering how sensitive the rotaries are to detonation, it might not be a bad idea to look into it! Don't tell me its too expensive either, I see all the bling bling wheels and rebuilds you guys buy! ;) Well, anyway, thats my schpiel, take my advice, and you might avoid feeding your precious turbine blades a shrapnel sandwich!
