Turbo kit over doubles your sleds horsepower, costs about $3000-$5000, mods required would be clutching. I wouldn't recommend doing this to a two stroke, you will blow your engine right away unless you completely rebuild it to withstand the extra power. May have to put in lower compression pistons. If you have a yamaha four stoke this is an awesome upgrade to give those sleds mega power with no other engine modifications.
