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 :)

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
