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. :)

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?

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

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

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

yeah stock motor, 19 yrs old.

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

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.

    • So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch
    • It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.
    • As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
    • Bloody apprentices! 🙄
    • Not sure yet.  Was considering speedtek because it was rated to 800hp, but when I did some research about him I don't think I will go for that🤣 So maybe giken gear set, but I'm afraid it won't be strong enough🙄
