It doesn't matter what part # or casting # is on the crankshaft...If it has the pressure rolled fillets on all the journals, then it is a turbo crankshaft...

You will find NA and turbo crankshafts with the same casting # on it...The pressure rolled fillets is just done as another machining process done after the crank has been casted...Personally, I have turbo cranks with casting #877 and #229...You will also find the NA cranks with the same numbers...

You have to visually inspect the cranks for the rolled fillets...That is the only way to know for sure if it is a turbo crank...
