How much horse power at the wheels is an N1 oil pump good for on an rb26dett?

at what horsepower will it put stress on the pump

thanks

ALSO: does anybody know where I can get a tomei oversized oil pump from for a good price. (for rb26)

I am willing to order from japan etc

thanks heaps.

Well i run a N1 pump and i push 450awkw. form what i have read on the forums is that the N1 has a brittle drive gear that breakes if you hit the revlimiter to often. I am currently scratching my head if i need to buy a JUN or a Tomei pump, because my engine has cost me quite a few $ and dont want to go through the entire process again after only 5 months.

450. wow thats alright then

i was told that 300kw at the wheels is pushing the N1 pumps.

I have been told I should use a tomei.. but yes, they are rather expensive.

Im looking at about 450awkw when its done

What other options are there?

JUN, Tomei... others?

are they all a similar price? and are there any to stay away from

thanks again

it really depends on how the car is driven.

N1 pumps tend to fail quite a bit on high rev drag cars, because of their rev limiter style, and the way they are launched....

at the same time though Jun or Tomei oversize pumps are a lot better, but it comes with a price.

      What should I do next to hold the head on

      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.

      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
