Any info on Nitto pump ?

Same thing was asked on GTRPWR when the CRD guys registered and posted once. Then they disappeared and never went into any technical details.

with a stock rb and no modifications what is the expected life span of the stock pump?obviously ill be upgrading asap and putting in a oil cooler at the same time but at what point do they typically fail?

That cant be answered.
Ive seen some early cars last and last and last. Couldnt really tell you why. But no body on this forum can tell you how long it will last. As long as the drive isnt stripping or have a crack in the pump gear, stay off your limiter and you "should" get plenty of life out of it. Its the bashing around on a loose clearance drive and pump on limiter that brakes oil pumps.

when you decide to update your oil drive, check out this link below for detailed info on the clearance issue.

Any new updates with any of you guys?

I know a couple of ya have used accusumps. Where or how did you rout your goods?

I've recently looked at the tomei and nismo sump baffles. Tomei has the rubber door flaps and the nismo has a different configuration using metal doors. I also seen rips extended sump for the gtr and appears that with the design, only a metal cup surrounding the pick-up with some slots in the bottom. Almost looks like a crank pully socket welded in. I'm using a tomei unit for the price. Tomei was only $140 or something close to that. I heard the nismo is crazy expensive. Like closer to $500? What ones you guys using/like?

Thinking about the oil drain modification. (head to sump) Most guys have been routing it to the driver side of the sump just in front of the front diff. I was pondering that if it were on the other side the cranks rotation would help suck the oil down with a vacuum. (crank spins clock-wise). I might just split my drain into two and have it go to both sides on my next build. Hard to test this theory tho, so what you guys think of that idea?

Any other new things that can be added here?

my car is street only (no tracks or autocross nearby) so I didn't go dry sump, otherwise I would have.

My oil capacity with cooler is 9L. With accusump is 12L. I have about 7bar oil pressure when driving. 2.5bar at idle. 300whp at 1bar fully built and -5 turbos. AFR is 9.8-10.3 at w0t. lots of flames from tail pipe haha.
