hey guys i got a rb26 with 350rwhp (in 2wd in a vl) atm on 17psi, with bigger inj, highflow turbos, pods, zorst, etc and i am getting the 4wd gtr sump enlarged and baffled as we speak and i was wondering what sort of power figures do i require a better oil pump?

whats the n1 pump good upto?

is it worth getting the n1 pump or another jap brand for the extra $$$???

im using the car mainly for street use and the occasional track day or drag meet if thats any relevance :rant:

cheers

ur stock oil pump will be fine for the power u have but i guess once u start making 300rwkw then oil pump should be considered, I would spend the extra money on an oil cooler, benifits from that are more than u know, i guess its not a matter of what hp is the various oil pumps limited to its more the point of how much u want to help ur engine?

does anyone know where you pick up and return the oil in an engine oil cooler?

they usually have an addition that comes from the oil filter location, just a supply hose to the cooler and a return hose back to the fitting. although no doubt it can be done differently.

as covered many many times the n1 pump is the same as the normal pump with a higher spring rate so it runs slightly higher pressure, you can do this to your standard pump for $20. Also if you are running an early r32 engine it would be wise to invest in a r33 on pump and a jun crank collar to address drive engagement issues the earlier designed cranks have!!!

so the N1 pump and the nismo high volume pump sold by nengun for about 1k are not the same aahhhh that makes sinces.So at wot level rwhp do you need to go to high volume pump ie tomei, jun, etc etc as i am running about 390rwkw and are about to upgrade internals and pump etc

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
