You don't need to replace the elbow, you just have to widen one or two of the bolt holes with a round file/dril bit. I've done it before and is a much cheaper option with no detremental effects. Also remember to widen the gasket's hole...I just widened all of the holes so that I didn't have to fettle with that and I could concentrate on the elbow.
Just remember you will have to run the boost lower of running standard parts and standard ecu
