For a normal 550-550whp RB26 twin turbo ( so no point to overrev to 9-10k) What would be the best bang for the buck for a early 90 wo are prone to have oil pump problem ?

I was thinking:

N1 oil pump but I would need to set my rev limiter to 8k...

Standard oil pump with upgraded reimax gears.

No point revving the RB26 past peak power @ 6800rpm.

I currenctly have my rev limiter set at 7.4k. I'm just wondering if a N1 pump can take abuse up to 8k SAFELY ? or at 8k this pump is at his max capacity? Like anything.. I prefer to have some ''play'' aka slightly overkill.

N1 is 250 shipped

and I can get a N1 with rebuilted reimax gear for 600 shipped..

Just wondering if I really need to pay 350$ more for a 500-550whp limited at 7.4-8k ?

Sounds like you have a stock bottom end, given you have the older oil drive etc.

Which then would worry me why you'd try to run 370-400rwkw through that bottom end.

Regardless of the oil pump, trying to push that much is going to end in tears regardless of what you do with the pump

Nevermind this issue. One thing at a time. I will be rebuilding my RB26. right now, I'm thinking about the oil pump.

So why are you buying bigger oil pumps on a small collar now then? IMO thats a more important issue any anything else.

Why not just do the smart thing and peg the power back a bit until you rebuild?

Having the small snout - as i said earlier - makes you more likely to bust stuff regardless of the pump you decide to use.

you could spent upwards of $1700 on a Tomei pump, for nothing!

And it's the reason Nissan clearly changed the design within a matter of years!

So your saying I should only change my crank instead of changing my oil pump ?

I'm saying changing the oil pump is not going to magically save your stock motor @ those power levels and you will still potentially have a failure due to the smaller drive.

Especially trying to pump 400rwkw through it.

If it was 300rwkw, no problem. Most R32 GTR motor owners know they are on borrowed time even @ that power level (for one or another reason).

I wouldn't buy a $$$ pump now, just run the motor till it dies and then follow your rebuild plan.

I understand your point. I was wondering because I saw on a local forum someone selling his N1 pump with reimax gear for 600$ ( and it might be cheaper since i might buy other stuff from him). Considering a reimax kit is worth like 700$+ the pump. I think it's a good deal. It doesn't mean I will be fitting the pump right now. I will when the rebuilt times will come. ( might be next winter, I'm slowly purchasing everything I need).

thanks for your advice.

ur best off just waiting alittle longer and buy new. if i was spending the money to build an engine (which i already have) i wouldnt wana do it half ass and put in second hand parts.

sure it might take a little longer to save and buy but at least u will have piece of mind that your parts wont fail.

do it right the 1st time round

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
