Water Pump, Help me

[Alex29]

Hi, my name is Alex, I am new on the forum, I have a 2001 Porsche Boxster S and today, after hearing a loud noise, a friend checked my car and bad news, the water pump leaked and the pump was broken, with smoke on the pulley ... So no more car, perfect

I checked with 3 mechanics and their prices: between $800 and $900...
It's too expensive, and I just changed the convertible top ($1700) so less money for the water pump would be better !!

I find this Kit on Pelican Parts ($317.25), on the top of the link

What do you think about it??? The rating for the parts is very good

I don't know if there is a big difference between this brand and the genuine porsche?

Is Pierburg a good brand?

Can you help me please?

Thank you very much
