Arif Posted April 8, 2013 Share Posted April 8, 2013 Is there a recommended service that should be done on RB26 motors prior to installing them? I searched but didn't come up with anything. I bought a JDM Z32 TT motor last year and did the 120k mile service which included replacing the water pump, thermostat, timing belt, tensioner, etc. I'm trying to figure out ALL the costs involved with buying a RB26.

BluDestiny Posted April 8, 2013 Share Posted April 8, 2013 Upgrade the oil pump. I've heard that's the weak spot. That being said, I would probably do the water pump an timing kit( if it was high mileage). Other than that just basic tune-up items.

ZT-R Posted April 8, 2013 Share Posted April 8, 2013 I put a brand new N1 oil pump on mine when i put it in, shattered it in less than a week. Buy a good oil pump, luckly i just happened to be watching my oil pressure and had my ems setup to kill the the engine with oil pressure loss. Other than that, just do a timing belt, water pump (stock,not n1), idler pulley, tensioner. I put a new lower timing belt gear on mine, but thats kinda up to you i guess. Make sure you have a good oil pan and pickup setup. Quote Link to comment Share on other sites More sharing options...

R3VO 3VOM Posted April 8, 2013 Share Posted April 8, 2013 Upgrade the oil pump. I've heard that's the weak spot. That being said, I would probably do the water pump an timing kit( if it was high mileage). Other than that just basic tune-up items. I always thought that it was the oil pumps on the early (like R32 series) RB26's that were a weak spot? Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 8, 2013 Share Posted April 8, 2013 The n1 water pump is designed for track use, not street use. if its a weekend car probably not that big of deal but do a bit of research on it if you like. Quote Link to comment Share on other sites More sharing options...
Arif Posted April 9, 2013 Author Share Posted April 9, 2013 Thanks guys. I know each motor has it's own strengths and weakness. It looks the service items are the same as my VG30TT. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 9, 2013 Share Posted April 9, 2013 Oh, dont boost over 13psi on stock ceramic turbos... I can attest to the turbine wheel sheering off. Quote Link to comment Share on other sites More sharing options...
nismos30 Posted April 9, 2013 Share Posted April 9, 2013 Thanks alot ztr, here in canada every engine needs a rebuild anyway and we pay 4000$ for them this is ridiculous but whatever.. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 9, 2013 Share Posted April 9, 2013 Dang, thats expensive for a swap in canada i would think. A basic rebuild doesnt cost much really, in the grand scale of things. Dont mean to sound like a jackass or anything but if your on a tight budget a rb26 may not be the right avenue... rb25 is good to about 500hp.

nismos30 Posted April 9, 2013 Share Posted April 9, 2013 Price doesnt matter only expensive to pay for a name instead of quality you know! Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 10, 2013 Share Posted April 10, 2013 Very happy with tomei parts. Yes you can find cheaper, but the R&D they do its worth it in my book. Quote Link to comment Share on other sites More sharing options...
helghast7 Posted April 11, 2013 Share Posted April 11, 2013 I've also read its good to install the oil pump collar on the crankshaft so that it makes a more full contact with the oil pump gear. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 11, 2013 Share Posted April 11, 2013 Yea but that requires crank removal for proper install. That's on r32. r33 and up where ok, you can google your serial number on your block to find out. Quote Link to comment Share on other sites More sharing options...

Is that only pertaining to the rb26 or is that the rb25 as well? Quote Link to comment Share on other sites More sharing options...
stony Posted April 14, 2013 Share Posted April 14, 2013 I ran my stock rb26 right out of the junkyard. If your not going to be full out racing a stock rb26 does well in a Z without doing allot of stuff. If it dosnt leak and runs with good oil pressure why mess with it. .

fast-datsun Posted May 29, 2013 Share Posted May 29, 2013 the oil pump problem is the drive on the crank not the pump. You can get a up-graded drive to fix the problem. N1 oil pump is only a stock pump with highter spring pressure for more pressure, no Volume increase if you want to up=grade use the GReddy, Tomie or other aftermarket High Volue pump with head restrictors... Always replace the timing belt and water pump. stock is fine for the street...... Quote Link to comment Share on other sites More sharing options...
djz Posted May 29, 2013 Share Posted May 29, 2013 The N1 pump is different to the stock pump in other ways that just the springs, I don't know who started that rumour but it needs to disappear. The housings are different, the backing plate is different, the gears are bigger in diameter. Quote Link to comment Share on other sites More sharing options...
ZT-R Posted May 29, 2013 Share Posted May 29, 2013 I shattered my N1 in less than a week with only a few light revs to 6000. Now I'm turning 9k on rips rb30 with tome pump and Mckinney (fast-datsun) pan. What a beautiful pan... Quote Link to comment Share on other sites More sharing options...
