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.

Ive heard the N1 isn't that great for standard cars..flow rates are different etc.

Nissan quoted me $160 for the real pump. I'm not sure some R33s use the same as the VL don't they - I know mine didn't - I didnt replace mine as it was in perfect nick.

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.

      R32 GTR fuel gauge not working despite fixing fuel level sender

      By XoRoKu · Posted

      Opened up the cluster to inspect the gauge itself for signs of damage and it looks good. Got curious since that needle doesn't go back to a "neutral" position by itself (it stays in the same position when ignition is off. so I manually moved it to 1/2. Connected it back, turned on the ignition and the needle started moving up! Not sure what's up with that but before that the needle was way down below empty like fully south west. There's always a chance that the needle moved slightly the first time I tried and I didn't notice because of how slowly it moves and how far it was from the markings. I don't know if the current needle position is accurate so I'll fill it up and see where that brings it. I guess I'll try to adjust it manually if it doesn't get to F. Looks like the needle position is relative and not absolute? Thanks all for your help and patience!

      rb20de neo +t conversion - boost pressure sensor needed?

      By GTSBoy · Posted

      You're confusing two different responders and more than one issue. The stock Neo ECU boost sensor is used by the ECU for protection purposes. It is essentially only an overboost sensor. It is not used for determining engine load for fuelling or ignition purposes. That task falls solely to the AFM. Any aftermarket ECU that either has an onboard MAP sensor or a plug in one, will use the MAP sensor as the primary load sensor. Or I should perhaps say "can", rather than "will", because some of them have the option of using other primary load sensors. That MAP sensor is not for the same function as the stock Neo boost sensor. The reason I recommended against a plug and play ECU is that they are intended to run a particular engine and usually in the car that the particular engine came in. So, if you have a transplanted engine in a different car, with some parts of the original missing (such as the boost sensor, for example) and therefore likely non-standardness of the loom and its insertion into the car's loom, then it is very likely that you will run into the same problems with needing to fix up wiring to make it work that you would with the stock ECU. And, if doing so for the stock ECU is enough of an obstacle that you start considering a standalone plugin as a solution, it should become clear that the plugin is quite possibly not the solution you'd hope it to be. It would just lead to more of the same type of problem solving work to get it going. In the above paragraph and in my earlier post, the lack of the boost sensor is not critical. It was just used as an example of something that we knew you did not have right, such that the stock ECU would not work. I took that as an indicator of a reasonable probability that there were other related problems hiding there.

      I can think of two places in my city of <1.5million population that specialise in automotive instrument repairs.Unless you're out in the wilds of Quebec, you have 3 major Canadian and 3 major US cities within the same distance as the single nearest city to mine. Surely there is somewhere you could send it.

      Can anyone shed some insight on this Turbo?

      I never cared for twins but whenever these conversations came up, I always presumed the higher number represented a larger turbo. Learn something new everyday.

      how do i install this 3 port mac valve for boost control?

      By joshuaho96 · Posted

      Interesting, I've never seen a failure like that before but with the age of these cars and the general questionable-ness of all kinds of parts these days you can't rule anything out I suppose. Boost leak testing the boost control system would've revealed this though.
