Re: Engine swap or turbo...
Actually, I am leaning toward both, as in turbo charging the Nytro (maybe, could be just wishful thinking). I bought my motor from SKE snowmobile parts, they are located in Minnesota. Motor was reasonable too, $2500 shipped, included everything needed to run, wiring harness, ECU, fuel pump, oil tank plus complete motor with nothing stripped off except for the clutch.
I am going to try and do all of the work myself on the swap so hopefully the only monies I have to spend will be just materials to fab motor mounts and hose connections, fabricating an exhaust and intake. I feel my largest challenge will be getting the clutches properly aligned.
Once I get the Weber out I will probably start a thread to show progress and what obstacles I encounter.
