i have seen Unique auto sports offering custom 7 litre sump for about $700, check out this link,

http://sard.com.au/pricelists/pricelist_skylineengine.htm

looks like a midified std sump, or try a local engenering work shop to mod yours.

Some quick questions that i asked High Energy and their response....

was just wondering the price of a sump for an r33 gtst rb25det? $600+gst for our Pro Eliminator

are these a c/o basis or buy outright?

Yes they are c/o pan and oil pickup

do they come with a modified pick-up?

Yes , mesh windage tray and x2 gates for better oil control on acceleration and braking.

what amount of oil do they hold?

6.5Litres

production lead time from date of order 2-3 weeks

hope this helps

To stop oil surge, probably while drifting - i'm unsure whether it's a problem with this motor, but it sounds like a better investment than a blowoff valve.

yes i want a baffled sump for a little extra assurance against oil starvation to the bottom end at high revs during hard cornering...

it's certainly not for drifting tho :P

Thanks for that link BU5TER.

there really is no point putting an aftermarket sump on ....just put an oil cooler on and see how much more oil it takes!

I have an oil cooler already, that cools the oil. Doesn't stop the oil pickup from not getting any oil though!

yep I've seen the UAS offering... it's larger capacity, but doesn't look like a baffled design.. thanks for the suggestion :P

I have never heard of an RB25 having dramas at the track. Merli tracked his old R33, which was internally std but with a HKS 3040 and Greddy plenum etc, AP 6 pots etc etc and making about 275rwkws with semi slicks. His car was punted regularly and never had starvation problems.

It would be added insurance...but really i see it as an extra initial expense, purchase + Labour. Then at $70 for 5L of Castrol, the cost of an oil change would soon get expensive, especially since i change my oil before every track day, even if that sump has only done o1 track day and 500kms of road use.

That said if you have the coin and already have all other basis covered, then do it....curious to know how much labour is involved to install?

just slap an extra litre in there before you go out  :)

I do not think you understand the concept of having the modified sump.

The extra capacity is there because it's a differnet size and can hold more oil before the level goes too high and starts becoming whipped up and airated by the crank, by adding more oil than is the maximum level on ANY engine that isn't dry sumped you will get air in the oil, and air in the oil going onto your bearings etc is bad.

The reason for the baffles etc is to stop the oil from getting away from the pickup, holding more oil is just a bonus of the system. By adding more oil to a stocker you arent getting the benifits of the modified sump.

BTW, after the track day where does this extra litre of oil you add go? Does it magically dissapear, burn, what? :(:P

you pull out sump plug

you drain oil

you put sump plug back in

I thought it was basic (sorry for the sarcasm there, need a vent while @ work for another shift)

If there is more oil in there, there is less chance of it being somewhere other than where the pick-up is one would imagine

But really, i dont think even modded RB25 (as troy said) have problems with that.

I was told i wouldnt need it for my RB25 (plan was to see track but didnt sue to selling the motor... damned EPA)

And seeing a few RB25/30'also punted around in 33's without modded sumps also who dab an bit more oil in there is my reasoning.

My reason for bigger/baffeled sump is one of insurance, why spend 10g on a motors internals and not do your best to stop oil starvation and killing the motor (again).

Plus i have heard when using the N1 pump that you can actually empty the std sump very quickly.

Im making my sump myself with the help of an engenering mate and with oil cooler and larger filter should be pushing the capacity up around 8.5 - 9L

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.

      It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
