The EightySixd Complete Power Package is hands down the ultimate motor for any turbo kit you have. Take your Polaris turbo to the next level! Once we get done porting your cylinders we send them off to get nickel-silicone-carbide. Then we do the rest of our magic and include a billet head and our turbo pipe for the best running power package that is on the market. You will not believe the extra power that your sled will produce and how much more of a broad power band you will gain!!
