Goal of this video is to show why we take our oiling modifications as seriously as we do. Your RB26 (all engines) need to maintain optimum oil pressure to stay alive and anything that can be done to ensure this crucial.

Thank you for doing the log testing; I have not seen that before! As an engineer, It’s really interesting to see the data there to back up all of these claims of oil flow, and to finally conclude that most of the issue is just sump capacity. This kind of explains why Porsche’s use high capacity sumps.

Running the recommended setups shown in this video on my built motor. She is running flawlessly up to redline. Being able to run an RB this high consistently without worrying about it blowing up is amazing. This is the way

Out of all the years I've been researching and combing forums, I've never seen someone post logs to explain. I appreciate that. Something critical to remember on why the RB has draining issues is due to the 10deg tilt. This results to drainage being limited to the exhaust side only. The hole diameter doesn't help either. Billet/spline gears, oil restrictor, extended sump, head drain and plum to sum catch can are a must for the RB.

This explanation is spot on ! I have many logs showing the exact same correlation pre & post pan extension on mine!

Great video, thank you for posting this! I’m currently upgrading to a nismo n1 pump with the tomei baffle kit, and an N1 2.6l Billet Oil Pump Gear. I’m running stock power on my r33 gtr. I’ll definitely do the extended oil pan when I’m ready to build it!

Thank you for providing an evidence-based assessment of this age old argument! I'm currently looking for a shop to put together my RB25-based Nitto RB28 stroker and this kind of analysis makes me think that your company should be my top choice here in South Florida! I need to swing by and take a further look at your operation it seems!

Great video, it's so nice to see claims backed up be real data and your stance on having a discussion with people who don't agree is really confidence inspiring. I wanted to ask if you would do similar oil control work on an RB20 as well, around the 350bhp range? Would love to hear your thoughts 😊

@ravperformance 10 күн бұрын

On the rwd 20 and 25 you won't see to many issues until big power or track/drift use. But the same concept applies just not as early and severely as the 4wd pan RBs

Tomei pump is also a proven pump with big power and revs. Extended Trust sump is fine if not lowered too much e.g S-tune suspension, have cleared many steep angles

@MollyDogsm 5 ай бұрын

It's not really a fault. Stock engine with stock power levels is unlikely to have any major issues result from this. That's really all Nissan care about.

What's your opinion on spline drive pumps? When I built mine I had a collar machined onto my short nose crank. My understanding is it eliminates any possibility of slip, which is still possible on a long nose.

@ravperformance 5 ай бұрын

If your flat drive slips, it's already too late. The idea behind the spline drive is more surface area, so less wear over time. With that being said, it's the better choice but a flat drive with billet gears will probably never give any issues.

Great information dude many thanks for taking the time to do this. Quick question, I have BNR32 with 30k kms completely stock except for R34 turbos, Apexi intakes and Catless Velside exhaust. How much extra oil would you add above the full mark? I don’t drive the car often and not really that hard however i am tempted to remove boost restriction pill as I have the R34 turbos is this a bad idea ? Really appreciate any advice you can give.

@ravperformance Ай бұрын

Overfill to the notch and run a 60 weight oil. Get an ecu with oil psi protection and youll be fine

@vannyboxadventures7327 Ай бұрын

Many thanks, are there any other options than replacing ECU? Would like to keep the car stock.

@ravperformance Ай бұрын

Sadly, no. Having an aftermarket ECU constantly monitoring and setup to react to low oil pressure is the best investment you can make. Plenty can offer this fearure without getting rid of the oem look and drivability

Great video! Have you tried with different oil viscosity? A 30wt vs 60wt is most likely a difference in the time it takes to flow back to the sump. Would be interesting to know what viscosity you are using in the tests as well?

@ravperformance 5 ай бұрын

I have, actually. It's almost not different at all. Will still lose pressure in the same spot. I have even done hot 30w and cold 60w tests. The cold 60w was a bit more dramatic of a dip in pressure. But 5psi is just splitting hairs when you are talking about a consistent 60%+ dip in pressure

@JapTuningSweden 5 ай бұрын

Interesting, thanks. The group N cars had stock oil pan but not a huge amount of grip when racing. The oil pump in Gr. N is not a high flow pump either. Gr.A is another story where both larger oil pan, high flow oil pump and different baffles in the sump were used. Again, great video

What are your thoughts on an accusump system for this issue? Either as an alternative or as an additional supplemental safety?

@ravperformance 11 күн бұрын

For dedicated track cars all day. For street driven cars, it's a lot to take care of and find space for. But i would only recommend an accusump as an add on, not a replacement for more pan capacity

@andreasgran9326 5 ай бұрын

So what is the total solution bigger oilpan,drain from catchcan to pan,baffles in top of cam covers and upgraded oilpump and pump gear. Can you get away with just oilpan upgrade or is it a bad idea?

@ravperformance 5 ай бұрын

Great question. As an experiment, i did the oil pan upgrade without changing anything on a car last year. Oil starvation was still nowhere to be found at 600hp. But because the other modifications are so inexpensive, why not do them all. Oil restrictor and pan baffle being the runner ups. Valve cover baffles are only really relevant if you are running a sealed catch can. But won't hurt

@cubegamer3905 2 ай бұрын

so on a bone stock long crank car the best way to prevent oil starvation and oil pump failure are to upgrade the stock oil pump to billet gears inside and to install an increased volume pan? anything else that you recommend to give the engine the best chance?

@ravperformance 2 ай бұрын

An ecu with the ability to monitor and react to low oil pressure. Along with other engine basics like knock, aft and temps

Did the extended pan have the Nismo baffle that Leask likes to use? Need to log stock pans with a non factory baffle (Nismo/Tomei/HR) that keeps the oil from going to the back of the pan on hard acceleration. I would bet that inertia and lack of oil control is more to blame than lack of oil volume.

@ravperformance 5 ай бұрын

I have done multiple stock pans with nismo and tomei baffles. Little to no change. I have done 4 pan extensions with the stock baffles. All over 600hp, all have perfect oil pressure to redline in every gear.

@chuckgf8 5 ай бұрын

@@ravperformancedo you have the data from the baffled stock pans to do a comparison with?

@ravperformance 5 ай бұрын

@chuckgf8 Yes, both the higher hp examples in the video are stock pans with nismo baffles. The oil pan baffles only help keep oil centered. If no oil is present, they don't help very much.
