i don`t suggest starting with a carb motor for your first turbo. there isn`t alot of info for this motor. they can take alot of time and money to get right. if you dont`get the jetting right they blow up really fast. the big strides in turbos were made after fuel injection. all the sensors and inputs required to run fi create a larger safety net. they can compensate to certain degree, while carb motors cannot.
i turboed an 03 800 back in the day and it took 4 tries (2 cylinders, 5 pistons) to get it to run.(it ripped when it ran)
this year i did an 08 700 boondockers pumpgas turbo. i bought the kit used, installed it and ran it. i still had to tune it but you can tune it in an afternoon, because all you have to do is raise or lower the psi numbers in the boon docker box.
jetting was minimum 30 minutes a change, not to mention cold gas running down your arms.
if you have alot of snowmobile tuning knowledge, turbos are fun. if you grumble and swear when your plugs foul and your sled won`t start,or you cant tell the difference between a clutch bog or a carburation bog, run stock
all in all i hope this post is helpfull.
