Water Pump Rb26

[cactu5]

Hi,

I recently fitted a new water pump for my RB26 while doing a rebuild. It began to leak water, and when it was pulled out it didn't appear to fit correctly meaning: "The pump had different bolt spacings, and the hole they provide is elongated". I've discussed this with the people I bought the part from, they are not entirely sure on which part it should be.

The part that has been fitted on the car is W900, this shop suspects that maybe it should have been W898 and apparently they have two reference points that say different things.

I was wondering if anyone has fitted a W900 water pump, or a W898 water pump on their RB26, and how it went?

Thanks.

umm yes....there is a difference as you've found out.

r32 rb26 block cannot use the pumps with the elongated holes. r33 and r34 rb blocks are fine.

nissan don't make an n1 water pump for rb26 if thats what you bought (not sure what the numbers you quoted above are, but they aren't nissan part numbers). there may be a standard water pump for r32 rb26 but I'm not sure (I've never looked for one)

the good news is it is easy to modify the pump you have. you just need someone to weld up the elongated hole then you can use it fine
