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.

    • Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.  
    • I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.
    • The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
    • I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.
    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
