Crankshaft Keyway Repair? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm finally looking at doing an SR swap and there's an engine I can get for a pretty good price. The only problem is the keyway for the harmonic balancer pulley is sheared. Can the crank and pulley be taken to a machine shop to have a new keyway and key put on 180 degrees off the original one or would it be cheaper to just get another crank?

I've seen the repairs with jb weld or loctite liquid metal and supposedly they can work decently but I'm not sure I would want to do it.
