Hi Guys,

Contemplating doing my timing on my '96 S2 R33 GTST. I've sourced the idler and tensioner bearings however is in the process of getting the timing belt and water pump.

The question is....

Where can I get the STANDARD, Not N1, water pump from (one that would suit the RB25DET not the VL RB30)? Would Nissan be my best bet? However, if the N1 water pump is my only option, then where can I get that from?

Lastly, would I be better off getting the GATES branded timing belt or would the genuine Nissan would be better?

Any help would be great. Thank you.

Steve

A standard or N1 waterpump can be purchased from nissan ( not a big diffenerence in $'s from memory ). If you do track work or drive hard, go the N1 pump otherwise standard dhould be fine.

Take your VIN / Chassis NO. with you to get the correct pump.

From what I've heard about timing belts, go genuine nissan unless you're pushing out big power. I believe the "Gates" ones are more noisey and the blue coating falls off.

Hope that helps.

i paid about 150 for the standard r33 pump from nissan, considered the N1 pump at the time was about the same price, the N1 flows less at lower revs than normal pump so dont buy it unless u go to the track all the time or u risk overheating in normal conditions.

VL pump fits too u can get non genuine ones from places like auto1 for around $80

Hi,

I've heard that the VL pump doesnt have a screw hole where the standard nissan one does.... and this in the long run will allow leakage... thats why i want to get the standard 33 pump... and i dont take my car on track or anything plus live in the tropics so i want one that will cool the car when in low revs... thanks guys

Hi,

thank you... I'll give nissan a go..

Lastly, why do nissan need the VIN/Chasis number to get a pump??

Also anyone know the price of a water pump??

If you are getting a stock nissan pump, the VIN Chassis number will ensure that you get the correct one for your car. There actually are differences between many of the pumps. A HR31 RB20DET water pump is slightly different to a HCR32 RB20DET water pump and so on. The differences are subtle but noticeable. My mate recently replaced his HR31 ( red top RB20DET ) waterpump with a N1 BNR32 ( RB26DETT ) one and the physical impeller difference was huge ! As a result, his engine temp on the track stays the same now, lap after lap. Better engine temp with street driving too.

I replaced my w/pump with the correct one for my car when I rebuilt my engine. The temp gauge never reached half way before the engine rebuild and still doesn't. :D

I changed my pump over 12 months ago with a N1 pump. Price difference wasnt much, but N1 was cheaper than a standard (then), so I got that. I priced them just a few weeks ago @ time of writing this and the price has sky-rocketed to over $300 for a N1 pump from Nissan.

I wouldn't put a VL/R31 rb30 Skyline pump on as the impellors are much smaller than a standard rb25 pump. (Im in the trade and compared all options.)

***A WORD OF WARNING IF CONSIDERING FITTING A N1 PUMP***

If you fit a N1 pump to a GTS-t (mine is a R33) you must fill in the smallest bolt hole which takes the smallest bolt when fitting, which is directly above the impellor, with Devcon (part # S-5), or something similar so that only the bolt will fit through it.

ie: on a N1 pump, there is an elongated bolt hole where the standard pump has a round bolt hole. This hole must be (almost) filled to prevent coolant leaking out. YOU CANT FILL IT WITH SILASTIC OR OTHER GASKET GOO as it will break down over time and eventually leak, and therefore you will have to pull it all apart again and do it properly.

I wasnt told this when purchasing so hence I had to do it twice! :-(

Apparently this hole is used on GTR's.

Just some friendly advice.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
