Water Pump question

[Onefast99gsx]

Well I went against a few of you and went out on my own mostly for cost reasons. Autozone didn't have the Duralast in house but they had a reman one. Didn't want that. I pm'd a few people on the dsmlink board that have more hp than I'll ever have in my day. I had to keep this on a budget and also wanted to get something installed today. I quoted wrong on the OEM ones. It's $158 for a OEM water pump from my nearest Mitsu dealer. Brookdale would probably have been $130ish. Still would have had to order from my local dealer. I just can't spend $158 for awhile.

Anyway, I went with a NWP557148 from NAPA. It's a brand new one. His suggestion and reasoning behind this was that it is a close fin design. "The closed fin design prevents cavitation and aeration at higher rpm's." ... was this dsmlink members words. He's been running this pump for years without a single issue.

Looking at the back side of it, you can't see the fins like you can with an OEM water pump. To explain, it just looks like a metal disc in the picture. It would be like looking at the backside of a turbo compressor wheel.

You know DSM's, always tearing them apart for some reason. For $61, I can change it out again the next time the motor comes out. Even the NAPA guy steered me away from the BA one @ $94 for this NWP one. It will be in the store by the time I get out of work. Gotta undo my timing belt job that I proudly did in 15 minutes last night. Sooo easy when motor is out.
