I've seen a few people post about putting M1000 engines in proclimb chassis. They seem to get the engines in and then peter out. Leads me to believe it doesn't work as well as people hope, or it's a bigger headache than it's worth. The one I saw that reported getting on the snow didn't seem to run well with the modified stock pipe, but better with a modified D&D pipe. So you may be doing a lot of tuning and trial and error to get the turbo running right.
After riding a lightly modded M1000, M1300, 900BB Suzuki Proclimb, stock Ctec, 900BB Ctec, and supercharged Ctec this is my comparison on powerplants. 900BB Suzuki runs similar, maybe a little better, to the M1000 without the weight penalty or hot mid-range issues. Stock Ctec is pretty snappy on the bottom and runs well for a stock machine. 900BB Ctec I rode was still snappy on the bottom, more so than the Zuk 900, but not as impressive in the mid or on top. I will say it was lacking some RPM and needed weight pulled from the primary for the elevation we were at. I got the impression a stage 2 kit would be almost or as good. M1300 and supercharger both have a TON of bottom end and both are thirsty! Supercharger maintains more on top at elevation. Supercharger system with water/air intercooler kind of equals out the pure weight numbers between them, but the super charger being mounted on the right side helps balance the weight out. Supercharger is less fuss pull and go ride and the M1000 or 1300 always worried about watching EGTs, water temp, engine mounts, something...
Summary: If you want something you can put together and ride right away with minimal fuss put the 800 Ctec in, maybe with a stage 2 kit, seal the intake, and have fun. If you want a tinker project that takes all season to dial in then try shoehorning that 1000 in there.
