Aftermarket turbo parts are WAY more expensive than OEM components. However, aftermarket parts offer a much larger range of tunability. A lot of it depends on how far you want to go with the power. If we are talking about a nice moderate 300hp build, then doing it with stock parts is pretty straight forward and simple. If you want 500-600hp, aftermarket has huge advantages.
