Hello all,

I'm currently building my rb25, into a 26/27- 87mm bore, 26 crank, 1.1 mm Cosworth HG so forth. I plan to track her a few times a year at some local courses. I'm planning on either using the JUN or N1 pump, not sure yet. However I also plan to run an oil cooler. Now the question arises on what to do for my stock rb25 sump for baffling, I'm a little unsure on how you guys do them, I have access to weld in pieces/trap doors to keep the oil around the pickup, but would just like to make sure I'll be doing more good than harm.

any pics, or info would be appreciated. I've seen a ton of info on baffling for the 26 sump, just not really any for the 25?

thanks,

-Cory

Hi guys, Performance Metalcraft do a good sump, wings baffles and one way doors. Works a charm. :)

PS; I have had oil surge in an RB26, RB20 and RB30 so I see no reason why an RB25 would be any different

They are about $500

given right oil restriction mods etc as part of the build... you might not need anything at all.

Surge comes from the oil in the head, and the sumps are a band-aid fix to this.

How much power and so on are you looking at?

330rwkw GTR's here run aroudn with stock sumps, semi comps and never have issues.

Looking towards 400-450rwhp ish, depends what my 35r can toss out on pump gas, I see most people fill their oil up to the first hump on the dipstick as well. My block is fitted with dual restritors.

CS_180 I know this has been covered before, I've read numerous topics and tons of pages about it. However I have found little info on whats done to the 25 pan, people say wings and baffles, ok I understand what they do, but its the placement I am unsure of, I'd like to make sure I'm helping my pick up not hurting it.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
