Rb26 Oil Pressure Drop

[Luke_ENR34]

nah, fully built, forged bottom end, head work, high volume oil pump.

Reckon i should be putting 6L in?

Last thing i want is it to lose pressure all up.

I ran 6.5 litres in my standard sump for 5 years. Thats both on the street and track.

what oil pump man ? and yeah 2l extra oil WILL save your engine. even with 5.5l mine would surge, 6.5 and no drop anywhere. with the high volume pumps and standard sump 6.5 is an absolute no brainer. have u ran yours down the quarter ?

edit this question is for luke, we all know about yours piggaz !!

No idea on oil pump brand. Brought the car with the motor built. It's got 34 vspec 2 turbos which I wanna upgrade to -5 soon along with injectors etc. Then take it down the strip.

Ill start putting 6l in and go from there.

you also had an oil cooler fitted to it

[Piggaz]

Either way, it was still at the very minimum at the middle of the hump on the stick.

Hey fellas im having this problem with my r32 gtr.

10-40 Royal purple

Stock motor, Greddy oil cooler.

put 4.80 litres in and its over the full mark just about the H

still getting droping down of pressure from 6 to around the 3 mark on my defi din gauges which arnt even 4months old.

Thoughts?

[Hadouken]

Put more oil in itt

[sultanaz]

So you recommend pretty much completely ignoring the H and L indicators ?

i always thought myself overfilling it by more then half a litre would be a bad idea

[Hadouken]

If you read what everyone else has been sayung in this thread then yes. That is exactly what i mean

[SiR_RB]

4.8litre isn't enough, put 6litre in

[sultanaz]

hmmm might have to do it then ..

still scares me but ahwel

[SS8_Gohan]

it's a good oil but stock motor yeah? how old? - just don't think 10/40 is thick enough for these old 26's. They need the Nismo/Motul 15/50 or Edge 10w60

imo, i'd try some Edge 10w60 and see how you go

[Hadouken]

I put some 10-50 in a month ago. I hated it, oil pressure stayed at 100psi for 5 min on cold start (this is in summer). Once warm if I give it a bit of stick I reached 100psi at 4000rpm. Car felt so sluggish, and cold start noise was much more prominent.

Dropped the oil and put old faithful 5-40 in. Oil pressure nice and normal and cold start noises gone.

It all comes down to the life the motor has had I reckon

Why does it scare you?

Oh for god sake stop worrying, nothing is going to happen everyone does it

would 10-60 be ok for a oil temp between 70-80 though?

yeah stock motor, 19 yrs old.

[SS8_Gohan]

19 yr old stock 26?! fair effort...

plenty more knowledgeable people in this thread than me, but IMO, i'd definitely go a thicker oil.

[sultanaz]

it was purely because the oil cooler rapes alot of my oil.. Should have used my head more ... got a 16row oil cooler ofc its gna use least a litre.

Put 6litres in like u guys said and its totally fine now..... not one bit of drop even at 180kph at drags

[jimBNR32]

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.
