Pretty in depth discussion on this from almost a year ago in the archive of this section or 3rd or maybe just floating around in one of the two open forums. Anyway, I think mazdaspeed7 partakes in it as well. I think you'd find it informative.

I saw a neat sign yesterday. It said *Stupidity is forever, ignorance can be fixed*.
Really nothing to do with your post, just a sign I saw yesterday. To the top now.

I remember hypntyz7 (aka rotaryresurrection) talk about doing it regularly. There may even be some kind of write-up on it.

Now, about this maintenance debate. I am personally a fan of water injection. Not the type turbo guys run to keep intake temps down, but the type you do in your driveway as a maintenance procedure. Find a vacuum line or lines (teed together) that feed both the front and rear rotors, grab the throttle and rev the engine up to 4k or so, and dip the hose in a jug of water and let it drink. The water gets pulled in, hits the rotors and turns to steam, and takes carbon (slowly) with it.
If you're starting with an original/old used engine, Id do this 3-4 times weekly for about a month to clean as much as you can out. I'd also do 2-3 gallons per treatment. From then on, once per month. IF Im maintaining a rebuilt engine, I do this once per month or once per thousand miles to keep everything clean inside.
I have torn down engines where I had previously done this treatment, and they are always very clean, if not carbon-less altogether. The water treatment, along with straight premix, would result most likely in a rotary engine that lasted over 200k miles as the rule, rather than the exception.

Im gonna give this a try when spring comes around.
Just out of curiousity, has anybody screwed this up yet? If so how badly?

to do this, you unplug the big vacuum line for the oil injectors and connect another piece of line to it and put that into the container of water, and it sucks it right in. you much hold the throttle open a bit or it will die. this helps motors that have been sitting and have stiff or stuck seals.

Other thing you can do is heat the water up and when it is already steaming start your engine and let the engine take in the steam.
