hi all. i think my water pump is in the way out. it has started to leak out of the little hole on the bottom side of it.

i was wondering if anyone knew how much it costs to rebiuld one?

and will a gtr or a N1 fit on to the rb20? as i plan on useing my car for the track and drift and an upgrade would be good.

thanks for any info

hey Damo,

I have done this myself. The VL - RB30 - Pump fits straight on... I got mine real cheap, contact the barn. should be around $50. If you get to doing that depending on your k's (low from memory) I would look at doing your timing belt (it has to come off anyway) and when you do your belt it is best to do your pulleys (idler and tensioner, $400 from Nissan, $90 from NSK) if you want some more help / advice, let me know!

You don't rebuild, you replace. I would run a genuine pump, mine is actually a genuine holden RB30E item (so Nissan in disguise)...

There is a suggestion by a few people that the RB30E pump will cavitate and not cool efficiently with sustained high RPMS; however personally I think the RB30 one is much better at say 1000-4500 rpm which is where you spend 95% of the time, it cools my motor much better than the original pump did.

The N1 pump is the ideal one. I belive it is a straight bolt up. If you can get one at a good price, then do it.

I know alot of people have problems with cars overheating in traffic who have N1 pumps on the mainland, as they don't pump enough water around for low rpm driving. But we probably can get away with it down here, as we don't have much traffic. A new stockers one would be fine, you wouldn't need an N1 unless it was a dedicated track car.

thanks for the replys.

i checked out nissan today and i can get a genuin pump off them for around $100 and around $80 of the barn but i wasnt sure if the non gen would be as good?

i had thought about doing the full service but its still about 30k off and i cant realy aford it. or more to the point i wont be able to fix up a few other things and do a brake upgrade.

thanks damo

thanks for all the input im going to get a genuine on. then i cna rest easy at night. i wont be doing the timing belt yet as i have just orded some adjustable cam gears from the group buy. mmmmm my rb will have some mid range. so ill do all the bearings and pullys when i fit them.

well im not sure. i plan on getting a tune after everything is fitted. most cam gears are set up on the dyno so i gess a quick tune is done as well. they are ment to improve lag and help the torque curve through the mid range. from what i have read they do make a good difference. they are in the group buy for around the $160 a pair which is realy good compared to the jap brand ones. these ones are made in the USA.

im also getting my new rotors out of the groub buy as they are half the price i can get them through my suplyer for.

      R32 GTS (RB20DE) Injectors Replacement

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
