Why not build a sdi turbo. The technology is here. I am talking about a motor 8:1 , 9:1 compression 8-12 psi of boost pump gas friendly. With fuel injection and active knock retard , why not give it a go. I look at it this way my 1988 SHELBY CSXT [ DODGE SHADOW] has a 3bar ECU with active knock retard and is driven daily at 20 PSI of boost on pump gas  . If my 17 year old 2.2 L dodge can have this tech, why not use it on a modern day snowmobile. If they build it I'll ride it. Just my 2 cents. what do you think? Anyone else out there a fan of forced induction?!!!!
