I just bought a timing belt kit for my r33 and he sent me the water pump for the r34 neo which part number is 21010-AA527 but the actual one for the r33 are 21010-21U26.

I have sent a message asking him why he sent this one and he repled

"Hi there,

They are interchangable to all RB25DET, MOST RB25 guys prefer that one because there had been a few issues where people had coolant leaking around the slotted hole on the 21U26 pump, that one does not have a slotted hole so the sealing surfaces are much more substantial."

Is this true or not?

Ha, I am looking into a new water pump, as I have my major service coming up. Looks like I might have stumbled across a good topic. What timing belt kit did you buy? I was looking at the Gates one that CRD advertise on here for $295...

Edit: I just found this link after my post. Looks like it will fit RB25DET....

Quote: "Side note: For those of you that install the RB pumps with the slotted holes, you must be very careful applying the silicone sealant around the slotted hole. If not enough is applied it will start to leak around that area as the surface area for sealing is very small. Pay particular attention to that slotted area when installing!"

Sigh, none left. I have left the seller a message. Hopefully, he just hasn't gotten round to listing another one. I had a looked for others in USA, seems they don't have complete kits. Selling seals, timing belts, etc. separately.

      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).

      EMU Classic. For what I need it to do I see no reason to upgrade. Link and Haltech would both cost an extra chunk of money for a lot of unutilized features
