hi everyone, I am starting to mockup a single stage external oil pump (wet sump) on my RB26. using a Ross or ATI crank pulley and thinking to use a Petersen single stage wet sump pulling from stock pickup and pressurizing the factory location on the block (not a big fan of moroso)

Curious who else has done this and if you have any photos or ideas. thanks

Single stage pump isn't anything new. It been done a million times over.

I have been doing them in kit forms for years, aviad single stage pump, 6061 alloy bracket, balancer, drive mandrels etc.

Now doing a surge tank type setup using a two stage pump to eliminate the oil surge aspect of running a wet sump/external pump arrangement.

thanks Brad, i searched but did not see anybody making a kit, I am sure this is not new but I have only 4 weeks until my next race and trying to work something simple without going drysump. we are definitely not interested to develop or sell these or be a competitor to you- just need to get my race car going...We can machine and fabricate the items, just want to have a solid plan together and not have to do things twice. would you mind posting some photos of your kit? do you sell parts/pieces or only the complete setup? also if you could elaborate on the oil surge, thank you

The single stage setup looks the same as this but only one stage on the pump obviously.

These photos are of the "surge tank"system.

Imagine a fuel system setup with an external surge tank. However using oil. The front scavenger stage acts like the lift pump in the fuel tank, and the rear pressure stage acts like the external pressure pump.

The tank has some airation baffles and things going on inside, it obviously returns back the sump same as a fuel surge tank does.

Geoff pretty sure aviaid or dry sump.com do a full rb26 kit (maybe an external kit too), they are not on the site but are listed somewhere... just cant find it atm,

i just got a full AVIAID dry sump kit (3 stage) with largest tank, cast sump (billet avail), ati balancer and drive, breather / separator all fittings etc for about the same price as decent wet pump and large capacity sump here in aus..... 12 day from order in cali to delivery here in aus... awesome.

Honestly any serious 26 i do again will have one of their kits. Speak to john schwarz @ AVIAID in chatsworth California, see what they have avail.

Mazworx get all their sumps and parts via ARE http://www.drysump.com/index1.htm which also do some nice gear.

      Use text replace function to auto-link to referred threads?

      By GTSBoy · Posted

      Hi, We've all posted some thread, or know of some other person's thread, that contains information that we want to send people who are asking question to. But if we don't have a link readily available, have to go do a search for the thread before being able to do so. So, it occurred to me that we could possibly utilise the auto-text-replace function that fixes some of my swear words to perhaps auto replace some special keywords with text that also has a link to the thread. A specific example. The thread that I did with the improved R32 GTR wiring diagram scans. If the phrase "R32 GTR wiring diagram" could be auto replaced with "R32 GTR wiring diagram" then all I (or @Duncan, or any of the others that refer to the thread) need to do is remember that that's the keyword (or phrase in this case). OK, it would be better if this keyphrase wasn't that long, but it does need to be specific enough that it doesn't get triggered automatically. And obviously there are threads on turbo topics, or suspension topics that we could treat similarly. Alternatively (and/or additionally), I've been thinking about trying to build a library of the real expert content that is trapped in the bowels of the 25odd years of this site. Things like some of SydneyKid's content. There are threads that he started that should be more easily found, and he has individual posts, or series of posts, in other people's threads, containing very good information. Some of us know that it is there, but....just have no memory of exactly where/when/how we saw it. If we had some sort of library thread, we could put posts in there containing links to things we've found, suggestions for how to categorise it, then a mod or other appointed thread maintainer can copy the link and any key text up into the first post in the library thread. There are probably many other ways to get it done. Some sort of wiki is probably the best way.   Thoughts?

      My thermostat had no gasket?

      By Duncan · Posted

      But, probably that happened to the last person too, which is why the RTV was there.....if you aren't putting a new gasket in you will need to seal the old gasket back to the metal surface with something, the gaskets will generally only work properly for a single use as they set/harden in that shape

      What is with the horrible blue and white bit in the centre of the wheels, didn't that come off with some scrubbing?

      Not sure how broadly you define Northside  but Castle Hill Exhaust are still around and could sort it.

      Wiring high beams in IC7 for R32 GTR

      By Duncan · Posted

      I haven't done this as I still use the factory cluster, but I do know the circuits for the flash vs on for hi beam are separate which is likely the issue. The ON runs full power through the switch and the flash uses the relay in the engine bay. I'd hit the wiring diagram per GTSBoy's suggestion
