oh, rev limiters kill the pumps too. if you have a "soft cut" limiter its not as bad. but a hard cut. (power fc) wont be helping. your crank is ok. it just dont like the revs and or limiter. and if you are reving it past 7k id be getting a better balancer. a r33 gtr n1 one at least :starwars:

What would you define a "soft cut" and a "hard cut" as?

Can someone tell me by looking at this list what partnumber would be needed for a r32 gtr with r34 n1 engine

probably somewhere near 400kw, and is going to be pretty much a race only car with next to no street use.

I've gotta get one of these before i put the motor in.

this is for Ati damper.

Cheers

Just as a side note the guy who builds (or used to build) kier wilsons GTR motors at wilall works at outlaw speed shop now. He says kiers car was running the "cheaper" of the 2 ATI balancers and was fine. So thats the one i went with.

This thread is making me want to buy an ATI balancer. Can i just put one on while my motor is out or will it need to be balanced with the engine internals again?

haha you and me both..

when they are back online (down for a big update)

I have seen those guys before, cheap prices. I ended up buying one from my local supplier for 700, more expensive but I support them as when i buy other parts like lots of speed flow fittings i can bring them back if they are the wrong ones etc.

My build if very basic with N1 pump but im going to balance the bottom end and run the ati balancer, hopefully will give me no dramas.

Cheers

Just bolt it on, they are balanced from the factory, unless the machine shop used your existing balancer to rectify any other imbalances

I spoke to a bloke at Ross Tuffbond today in regards to one of their balancers. I think for many of our applications (mostly street driven sub 400kw cars), the Ross balancers are more than suitable. While the ATI ones seem like an excellent product, theyre also very expensive at over $800 in Australia. Although i have come across new ati balancers on ebay for about US$350 + $100 postage, but these were for chevy V8's etc. Im yet to get an email back from them as to whether they can get RB26 ones for the same price.

Anyway, the guy from Ross said they've developed a pulley that attaches to the harmonic balancer that drives an external oil pump used in a dry sump set up. Im thinking of heading down this path eventually in an effort to bypass the poor design of the Nissan oil pump drive. I havent researched it yet, but surely it can be done for less than the price of a Jun or Tomie oil pump (>$1500!!).

Anyone know anything about dry sump set ups???

ati balancer for 430-490 us for rb26 listed in the site i mentioned before.. horsepower parts

now as for drysump. i been looking at it for months, and i seen the costs of your typical normal setup

jun pump 1500

enlarged sump around 1000 ?

oil return mods 300?

now as for drysump.

the pump and the lines are the killer.

atleast 1000 for lines,

and atleast 1500 for a 4 stage pump and that only goes upwards.

tho you can source used pumps and systems from nascar teams in the states for rather cheep. and they have all the parts you need except lines...

check ebay usa for them..

i have since forgotten about drysumping for now

Yeah, i hear what youre saying. I just did 10 minutes of searching on this forum and quickly discovered that dry sump set ups are way out of my league.

There goes that idea!

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • 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.
