Accu-sump good or bad and why ?

[evilgtr]

I want to get one but don't know of about them, there was a recent article in modified magazine were they fitted one to a r33 Gtr and I know alot of Australians run them as well as the S2K guys . What do you think about them ? Seems like another line of solid defense against the poor oiling of the RB..

When it comes to that, it's a great addon to a badass system but when you add up all the parts, it's best to go drysump. For a track car it would do well but pointless on a street car.
Oh, here's a sticky about oil systems on the GTR tech page. You are more than fine at your power range with the pump you have. Just respect the rev limits!

RB26 oil system

[evilgtr]

They are reasonably priced and you can buy the entire kit with what looks like all the necessary parts to install in on the Gtr ? In the article it looked faiy straight forward ?

I know it's not needed for a street car but wouldn't it be handy to have for safety reasons if you wanted to do the odd track day or auto cross ?

How much is a drysump system on a rb26 ?

I think an accusumps runs around $600. I believe it installs behind the seat or where the A/C compressor is if you want it in the engine bay. They do take up some room. You can get nearly $4K into an oil system pretty easily when going for badass, oversized sump, oil pump, accusump that is. I've seen dry sumps around $7000 for sure, I've seen cheaper. Dry sump FTW!!! IMO If you're worried about your oil system for a street car, get a good oil pump and cooler, watch the revs, most guys will do this. The ones who use larger sumps/pumps and accu are normally track guys who will do really crazy stuff. If you're going track, the best would be to go dry sump.

Here's what you want:

It's the cheapest insurance you could ever buy. Plumb it in to the return side of your oil cooler and you are golden. Even if you spend $1000 on an N1 pump, the collar and a Trust baffle kit/sump extention you still could get a moment of oil starvation if the stars align just right.

Dry sumps are the ultimate but if you don't want to rev to 10k or race for 24hrs at a time, it's not really worth it if you can't put it together yourself (for about $1500 if you fab everything yourself, $8000 if some shop does it all).


This is a no brainer for the price, you can also pre-lube your engine after it's been sitting for a while by just flipping the ball valve handle.

Jon thank you for the link I'm going to research that more when I have time, seems very similar to the Accu-sump ? Nismo-stune and Jon - the reason why I'm looking at extra insurance is because I'm questing whether or not my oil Pam baffle was installed in my build.. I think it got left out Fml. Is there any way to tell that doesn't involve me pulling the engine ? I have a bore scope so I can look through the oil pan plug if there is something definitive that will confirm this ?
I would like to try some auto x this summer but if I don't have a baffled sump to comets my oiling upgrades then I will not risk it. I don't know the limitations oft stock baffle but I dont feel lime doing another rebuild

An extra quart of oil and an N1 pump should be more than ok to auto cross. Most people don't use serious oil systems. The risk will always be there. Like flashing in a freshly built head, anything can happen... lol.

Some mount Accusump tank infront of radiator and have cable running to cabin to activate valve on Accusump tank, like in this thread (R33GTR show / dragcar, built by R.I.P.S) -

Always slightly overfill my cars engine (RB20DET) with oil. From memory, was up to H mark on dip stick.

From what I understand, dry sump is better, as oil is removed from back of head (one stage), sump (one stage), etc by multi stage (4 stage??) dry sump pump and sent to tank. Then I think from tank to dry sump pump, then back to where oilfilter goes (via sandwich plate), back through oilfilter, engine oilcooler, engine. Then the cycle starts again.

R35GTR engine runs a semi wetsump setup and has a pump (main oil pump?) drawing oil from back of heads. You can run a drain from back of head, as engine tilts that way under acceleration, but I gather it's best to have pump to remove oil from head.

R35GTR semi wetsump setup interest's me, so if anyone has detailed info on this setup, would it be too much trouble to ask you to share it???

[evilgtr]

Hahahahahaha **** hey what are he odds of that ! What a piss off. So you feel n1 pump tome orifice and a extra quart should be sufficient to auto x or do the odd track day ? Gtr-dad was saying he did one hard track day on a stock engine and the next day had rod knock..

[NismoS-tune]

A 20 year old car could very well do that but a fresh rebuild could be different. Some people simply drove to the store one day and BOOM!
