Use gt3 water pump with metal impeller?

Very interesting. They are very respected in the area and pretty much only work on Porsches and have for over 50 years. I'm surprised he would recommend an approach that seems so obviously wrong based on the feedback from this board. Thanks for the great feedback. I'll run the concerns by him and get his thoughts. Should be interesting.

Ask the shop if the metal impellar water pump they install fails and digs into the block if they will cover the damage. That should be an interesting discussion.

I saved my old pump. It was scraping the block. You can see the marks on the impeller if they don't believe you.
