You are gambling big time using "unknown" Chinese suppliers - I bet they'll run a mile when their pump grinds through your block....

DONT use metal impeller water pumps - even if they fit initially, any slight wear on the shaft will cause the impeller blades to wobble & grind away your aluminium block = new engine !!

You are messing with one the cars major systems - why would you go cheap when the downside is total failure and huge $$$. A genuine Porsche pump costs peanuts in comparison.

I won't even comment on the filing of the impeller blades to make it fit.....
