dAVE Posted April 19, 2004 Author Share Posted April 19, 2004 Also, heard that you can get these from autobarn, but typically they dont have it listed so cant help... and part numbers would be great thanks Link to comment https://www.sau.com.au/forums/topic/38903-water-pump-replacement-rb25r33/#findComment-789157 Share on other sites More sharing options...

dAVE Posted April 19, 2004 Author Share Posted April 19, 2004 Cheers for that... Also the N1 water pump suits and is around $160 from Nissan I found out. Im thinking I will go the after market... can you see any problem with that?

sidewaymambo Posted April 19, 2004 Share Posted April 19, 2004 mine is $80 VL aftermarket, when my old pump off the car, I could not really see the difference (a little bit on the fin, otherwaise the same), and it works fine to me.. The N1 seems big, should provide more water flow..however mine is fine with VL..

predator Posted April 19, 2004 Share Posted April 19, 2004 The aftermarket one also available is "powermax" comes in a green box.. can get from Supercheap.. Around $70 I think the N1 could be overkill on a street car.. Apparently people do notice some cooler temps, but I've never had overheating problems. Maybe on a track car coul be worthwhile, but otherwise..

dAVE Posted April 19, 2004 Author Share Posted April 19, 2004 Gavin woods recommends N1's when he does the 100km service. Few SAU people have them now. Will go into Autobarn / Supercheap tomorrow and get myself a VL RB30 water pump Link to comment https://www.sau.com.au/forums/topic/38903-water-pump-replacement-rb25r33/#findComment-790053 Share on other sites More sharing options...
benl1981 Posted May 1, 2005 Share Posted May 1, 2005 Do you guys have Series 1 RB25DETs? Apparenlty one bolt hole is different..is that a problem???

Duncan Posted May 3, 2005 Share Posted May 3, 2005 Not sure about the series 1 RB25, but the 32 GTR and 33/34 GTR do have different pumps, a longer hole needs to be welded up for use on the 32 gtr.

NZM.031 Posted November 19, 2008 Share Posted November 19, 2008 yeh you have to modify the n1 pump, an rb30 one will work fine.; also read when i was doing it, that the n1 pump, with its larger spacing and one less blade, is not suited for traffic situations, great on the open stretch or track, but idling away it doesnt flow as much... as its designed for higher than stock rpm, hence the larger space and one less blade.

s13rb20pplater Posted December 2, 2008 Share Posted December 2, 2008 thought id bump this thread as the question is asked often so the vl 3.0det wp, is compatable with the rb20det and rb25det?

bozodos Posted December 3, 2008 Share Posted December 3, 2008 Yeah I'd like to know this as well - my RB25 water pump is leaking so looking at a possible replacement.

BH_SLO32 Posted December 6, 2008 Share Posted December 6, 2008 Yeah I'd like to know this as well - my RB25 water pump is leaking so looking at a possible replacement. The RB25 water pump has an elongated hole for the small bolt on the top side of the pump, the other RB pumps don't have the elongated hole. The location of the small bolt hole in the RB25 blocks is different to the RB20 and Rb30 and consequently if you use an RB20 or RB30 water pump you won't be able to install the small bolt. All the other bolts however, align correctly. I have found in the past that Nissan is cheaper to buy an RB25 water pump than Autobahn.

bozodos Posted December 8, 2008 Share Posted December 8, 2008 So therefore I'd be best off sticking with the OEM one then, rather than trying an aftermarket RB30 replacement?
