Hey all, new here.

I am building a RB30 twin turbo engine for my R31, I am upgrading the oil pump, but im unsure what fits straight in and what doesn't

I am under the impression that the RB26 oil pump requires a collar to be added to the front of the RB30 crank?

any advice/thoughts appreciated.

RB30E and RB30ET oil pumps also fit.

:blush: cheers :D

ORLY?????

who would have thought.

I would have used the RB30E pump, but everyone is saying that it'd be silly to do that, as the engine would probably run out of oil, the pump would have to support 2 turbos as well, so its upgrade time.

MAG86, i didn't think it was too bad, I was going to go with Suck_my_fat_wang, but it thought that was just a little over the top :wave:

the best usernames are allways the ones that cause a littel controversy!

I could have allways gone with Jihad_in_my_pants, Im sure you wouldn't have any probs with me slaggin of on a religion that isnt yours? (big assumption there, sorry if im way off)

anyways, thanks for the info fellas, much appreciated.

so how did you go with that on the RB30 crank, did it need the collar fitted?

I haven't fitted a collar yet, and im sorta thinking i wont need to, as the engine isn't being built for revs.

to my understanding, thats the main thing that kills them?

Im running a 32 gtr pump on mine, havent had a problem, went straight on, way cheaper then the rb30et ones, and i wouldnt even bother with the standard rb30e pump, looks the same but flows different. I have been told that all rb series blocks share the same water and oil pumps, but someone might have to verify that..

    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
