Just like to get a confirmation before I go ahead and buy another pump.

Are rb oils pumps interchangable. Specifically rb20,rb25 and rb30. I don't want an N1 as i don't have a crank collar and I can get a standard rb20 pump at a good price..

Found this thread: http://www.skylinesaustralia.com/forums/topic/123932-interchangeable-parts/

which says yes but double checking before I commit.

Thanks

I don't know about the RB25 oil pump but the rotor of the RB20 is 9.3mm thick whereas the RB26 is 11mm thick.

I couldn't source a RB20 oil pump for my 20. I installed a 26 oil pump and it's working like a charm.

The na 30 pumps less than the turbo 30 pump. They are all different butwill allbolt on.N1 pumps break due to huge revs and potential misalignment caused by line boring, combined with the small drive contact on the crank. All pumps barely make contact on the crank drive. what are your goals for the engine?

Used in a drift car. So high revs constantly.

Makes 260kw so not huge power.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      Yea that's a fair assumption. I'm presuming they call them solid lifters as they have no moving parts like hydro lifters.

      Why am I hitting a power wall with my stroked RB25?

      I believe you're confusing WMI with water injection. Looking at that graph, the 93aki+WMI car is making more power than C16 race gas. Boost juice, which is what I also run, is Snow Performances 50/50 premix.

      GCG is a good company, they're a major distributor for Garrett in Japan as well.

      Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣

      I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
