600 ho

Anyone seen any big bore kits, turbo kits etc for the little 600 motors? Maybe a idea for a custom turbo kit. Sled is a 2014 m6000 sno pro

Ill start off by saying that I just purchased a 2007 RMK 600 with a 155" and it has an aerocharger turbo on it. The engine was seized up when I got it from the dealer. I disassembled it and found one piston melted down so Im now in the process of rebuilding it. I have a couple of questions...
