11 bolt water pump source?
My 11 bolt water pump just started leaking through the weep hole. This was a polished aluminum pump installed by the PO. Didn't last 2K miles.
Who has the best OE budget pump? Do any of the Rock Auto or Summit pumps have a cast iron impeller?

The machine shop that did my engine last year used a PRW unit. I've been driving the crud out of the car this past year and haven't had an issue with it.

And unless your racing and and looking to shed every last Oz of weight a cast body pump is the only way to go for max longevity.
