Local Indy will be replacing original water pump and stat on my 20 year old 996 (64k miles) on round two of maintenance. Pelican states the Porsche pump has a composite impeller, Pierburg is metal (and $100 cheaper) and GEBA is composite and the same price as Pierburg.

I plan on keeping the car, and as both P and G are listed as OEM, not too worried about either one, unless someone can talk me out of the composite.

I’m embarrassed to ask this, but since I moved to FL, and it’s quite a bit hotter than PA, should I bother with the colder stat, or just forget it. Most of my driving is on relatively empty roads, not a lot of sitting in traffic. I know there have been extensive discussions about this one.

Don't do the metal impeller, when it starts to go it ruins your engine along with it. There's a reason why Porsche OEM is composite/plastic.

+1 for the low temp stat. Low Temp means the functional operation of the unit, not ambient air temp or environment. A low temp stat just means it will start circulating coolant through the radiators at a lower temp (sooner) than the stock version, definitely beneficial in warmer climates like FL
