Which Water Pump For A R33 Gts-T

[STARSKR33M]

Hi all, i have been made project manager of my bosses r33 gts-t's upgrade and maintenance schedule. I am planning to change the 100km service items before embarking on a 380 kw rw upgrade quest. I am just wondering if anybody has had experience with genuine/ non genuine water pumps and what there experiences were. I am currently thinking about a protex N1 spec item but am unsure whether i should go non-genuine or nissan part. Any opinions would be appreciated.

i'm not familiar with the protex stuff, but my advice would be to stick with the genuine nissan pump. they are reliable and work well. the water pump only plays a small part in engine cooling. a bigger difference will be made by the quality of the radiator.

thanks, i am only considering non genuine as the N1 nissan pumps are $585 while the protex one is considerably less, i am on a budget to complete all the service items and attempt to get the performance mods also within budget. If there is minimal impact in pump performance going non-genuine i will go non-genuine and use the additional cash to buy a alloy cooling pro triple core radiator with the saved money

just jap have the N1 pump for $380. they also have the stock rb25 pump for $175. what sort of use is the car going to see? if it is going to be purely for track, etc then go the N1, if it is going to see regular street use then i would be going the stock rb25 pump. the N1 is designed for higher rpm use, so at lower rpm it doesn't flow as much (at least that is my understanding).

just take note that a lot of people have had issues with non-genuine pumps in the past and have ended up putting genuine pumps on afterwards. in fact a lot of people have had more success with rb30 pumps than non-genuine. if money is tight then definately go the genuine rb25 pump over a non-genuine N1 unit.
