Rb26 Oil Pressure Drop

[R.3.2.G.T.R]

just found this thread.

i noticed a bit of pressure drop especially in 1st/2nd, nothing alarming, but thought it odd.

those that have contributed to this thread a while back, how are you guys getting on with filling it to where you have??

on a stone cold engine, where is your oil level on the dipstick?

on a warm engine, say after 10-15mins after shut down, where does it sit?

im on a stock sump, jun pump, tomei baffle and head restrictor, i filled to just above the H.

but going by this thread, seems it may want to be closer to the hump than that.

ill put an extra 0.5ltr in and see what happens, cant harm anything a little extra oil on a pump like the jun.

?

??

whats to question?

i run a stock sized SUMP, and an uprated JUN oil PUMP

(not sure if you read it as stock pump and jun pump?)

anyone care to let me know how there doing running a bit more oil with your setups?

anyone?

I would say that they would be running more oil because they are smart. If you are running a stock capacity sump with a higher flow oil pump and you go to the track, I think that your pump will drain your sump. Hence, bigger pump = bigger sump

Piggaz was doing track days with an overfilled sump with no problems

he had a Jun baffle though and his N1 pump (that is no longer serviacable might i had ) has a bit less flow then you

i ran around the streets for 6 months with 400RWKW and a JUN pump on a stock sump with no problems... Filled the sump to 6L

[GTR_JOEY]

Might i add i also had crankcase breathers and restrictors in my engine

[jimBNR32]

Where does 6ltrs show on the dipstick when the engine is cold (overnight)?

[GTR_JOEY]

the bump in the dipstick??? dunno cant remember... i got a 9L now

[Piggaz]

Middle is about 6 - 6.5...IIRC

Just put 6.5 in and call it a day.

[jimBNR32]

Cheers for quick replies.

Why do you have 9l now?? Was there a reason you decided to go for an extended sump instead of overfilling?

Piggaz,

So middle of the hump when looking at the hash side?

[GTR_JOEY]

420rwkw+semi slicks+ track use...

it needs to have a baffled sump.. overfilling works to an extent but i properly set up sump with baffles and trap doors is the second best thing after getting a dry sump

[jimBNR32]

I do have a tomei baffle and head restrictor too.

Edit:, surely have an extended sump also for 9ltr?

Just trying to work out what I can get away with.

that helps.. i would still overfill though

[ali-turko]

I agree with joey , I ended up spinning a bearing, overfilling works to an extent!

Fix your oil pressure issues properly with an extended sump!

Or you be up for a new rebuild like I was..
