Do the OEM Porsche water pumps also have plastic impellers? Don't think so.

Thermostat: there is a downside you should mention when you use 80 degree thermostates. The fuel ratio is managed by the ecu. If the ecu thinks the engine isn't warmed up full it adds more fuel. That means more fuel consumption and maybe a little bit more power on the good side. On the bad side the engine oil gets thinned with fuel. I hope everybody knows what that means on the mid to long run and why i'm not a fan of that. Best would be to make shure the ecu thinks the engine is running at 90 degree celsius water temp - while it's running a t 80 degrees celsius.
