Do the GTR N1 water and oil pumps directly replace the standard ones on an RB26 motor?. Sorry if its been posted before but I did a few searches and found nothing...

How hard are they to replace? I am planning on doing the cam gears and belt and think I read somewhere that its a good idea to do the water pump at the same time. I want to do the oil pump too though....better not be an engine out job. Any tutorials around on SAU??

Also can the water and oil pumps be had for any cheaper than $380 and $530 respectively? I found those prices online.

cheers

Tom :cool:

Those prices are about right, I dont think youre going to find them much cheaper.

They do bolt straight on however, the N1 water pump isnt reccomended for daily driven cars as the flow less at low rpm than the standard one to avoid cavitation at consistent high-rpm. So if youre stuck in a traffic jam, the N1 will be pumping less water than the standard RB26 one.

N1 oil pump is fine for daily driven cars and yes I would consider it a worthy upgrade.

Still a point of confusion as to the difference over the normal oil pump, some say it just has a higher relief spring pressure and someone else has actually had two apart side by side and said there is noticeable internal difference in them.

Either way theyre not much more than a standard pump and push a bit more oil pressure than your standard one, so definately not a bad thing.

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
