I have a 5 minute old N1 Water pump for R33 -34 GTR for sale. Asking $260 including postage to anywhere in Aus

I incorrectly bought this brand new last week for $340 and fitted it to my R32GTR to find that it doesn't seal correctly. I have just rang nissan and have been told there is a slight differance for an R32GTR water pump and this pump will only fit a r33 - 34 gtr hence why it wouldn't seal properly. I rang the car on the host for 5 min with the water pump on, that's it. Still brand new! Have reciepts ect.

whats the difference?

i was always under the impression that all RB water pumps were the same. hence why i want to run a N1 pump on my RB30/26dett

Premo,

There is an elongated bolt hole in the N1 water pump which seals correctly on R33-R34GTRs but for a 32 and probably rb30 you need to tig weld the hole up and re-drill the correct size. Otherwise it leaks from here. Other than that is identical.

hi mate sorry to chat in your thread but weld it up and it will work fine - AFAIK there are no r32 n1 water pumps - better check nissan didnt give you a standard 32 one instead

Duncan,

I've since done the research and found out exactly the same thing. It is a genuine N1 pump and requires the elongated hole to be welded up. I had already purchased a new standard pump and fitted it SO IT'S STILL UP FOR SALE if someone wants it!!! I couldn't be stuffed changing my pump again.

Price is $240 posted as above.

Have a look at the photos on this post, there is one long hole close to the impeller, this needs to be filled in with a welder and redrilled to a 6mm bolt only on a 32gtr though. It will seal on a 33 and 34 as is.

use some liquid metal putty to fill the hole (allow room for the bolt though), done it on mine and had no issues and plenty of others have done it. saves welding it and distorting the flange surface if it gets too hot. about a 5 min and $10 job to do it :)

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
