I've got a total of $1500 into my skidoo turbo setup including machining the head and got 6000km on it at 10psi. Just rebuilt it for preventative maintenance w new crank jugs and Pistons. The crank did have .017 runout but still ran fine and the Pistons actually looked mint. Not a single deto mark. I did it all w used parts as far as the turbo setup and all brand new skidoo internals. It'll cost about 6-7 hundred to turbo my 300 roughly. I've got all the parts now minus a couple guages
Ya......thats cheap. Nice work!
