I am looking at turbo kits and am wondering which turbo would work out better. The bike would be for street use mainly. The engine is completely stock. It is a 2005 with just under 11000 miles. Does any of the bottom end be replaced, studs, rods, bearings crank. Also, is it worth replacing pistons with dish pistons or is it ok to run stock pistons with the spacer? I am not looking for huge power. 225 plus or minus is ideally what I want.
