okay while my 25-30 is being rebuild i thought it would be a good idea to put in a custom sump, with baffles, and a larger volume.

i can send it into adelaide and they modify it with a hi-energy sump but its 700bux. i wanted to make my own.

anyone have detailed pics of what theirs looks like or any advice in general would be greatly appreciated

thanx

nice sump mate, good to see rb30 in the states (dont forget to tell eveyone where the block cam from :D

got any pics of the baffles also.

the rb26 sump would need an extra mod to rid the front shafts- so thats one reason not to.

what sorta baffles do they have inside??

also wouldnt the stroke of the 30 hit the standard baffles on the sump??

Funny someone should mention this as im in the process of fabricating an ally dry sump pan at the moment. Different to a normal gated sump with extra capacity, just a very shallow pan with a few valleys for the two pickups for the pump. When i get closer to finishing it ill get a few shots of it and pop em up. At the moment ive only got the flange cut out, and other peoples paying jobs come first unfortunately. If only there were more hours in the day :D

Not sure about the stroke, someone will know that

Yeah, its no big drama to remove the front diff.

Mine was done in that manner.

When 350-400rwkw GTRs run around here in melb with the stock sump on semi's...

That kinda tells me the stock sump works quite well and would be good for 99% of setups out there

Im with Nismoid. Why bother with a big dollar or even custom sump when the OEM item with the diff removed and baffles fitted with sufice perfectly.

If you fit an oil cooler you have increased the volume slightly and honestly if your going all out ditch the sump and use a dry set-up straight up.

Greg's S15 with the RB26 fitted runs a factory sump and has no issues whats so ever and Id garantee it takes a lot more circuit abuse than 90% of the other cars getting around.

From cubes DOHC guide: Grind off the RB20/25/26 fins towards the back of the sump, the rb30 crank and rods have a longer throw and will foul. The RB30 sump has no clearance issues in the R32/33 Skylines.

My car has the standard RB26 sump with a tomei sump baffle in it and no issues to date what so ever with oil pickup.

Have included some random pics I have on my computer of a custom sump for an RB, I like the design of this one....

Dave you have any form of aftermarket sump baffles fitted???

We run tomei baffles in all of out RB26's and never have any problem with surging. Ive got guage in my GTR and after 100's of wakfield laps, oran park and eastern creek laps Ive not once seen a fluctuation in oil pressure.

I usualy over fill by a litre anyways but only because the thing still leaks out the crank seal when it gets really hot.

    • If that's the wiring from the factory, I'd be inspecting the loom everywhere.   Any signs of that anywhere else, and seriously, I'd get rid of the car ASAP before the electrical gremlins make it worthless, or it goes up in flames on its own. That is scary how that insulation is failing!
    • I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies. 
    • It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest. 
    • Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks! 
    • It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers
