If only the very ultimate pump is what you're looking for then this is it.

The 12JR Race Pump uses a severe duty Aquamet pump shaft, a lightened, balanced,
and blueprinted stainless steel impeller, an inducer pre-loader impeller, and a double drilled bowl with a billet aluminum bowl stuffer. We then flow prep and clearance the assembly to race specifications and finish it off with a proven Berkeley Droop Snoot.
