I'm releasing a fantastic new oil setup at the moment which is a hybrid dry/wet sump system.

Using a 9L fabricated sump, 2 stage pump and a "surge tank"

The single scavenge stage draws from the 9L sump and fills a 2.5L resiviour (surge tank) mounted inside the wheel arch or engine bay. The single pressure stage draws from the resiviour and pressurizes the engine.

From the top of the resiviour a return back to the sump allows the tank to breath and overflow.

Pro's

As good at controlling surge as a full on dry sump

Far cheaper than a dry sump

Less plumbing

External pump so no breakages!

Lower weight not having the large tank and lines

So far testing has been faultless with perfect oil pressure logs when running on slicks.

I've also just completed the first prototype resiviour to fit into the original space occupied by the washer bottle on the R32.

Do you have a set of baffles in the tank Brad? What capacity is the tank? Looking at the D.E. or Verdi pump with an air/oil separator the design of the tank can be a lot simpler which owes itself to

Ryan I have two Vehicles already doing some laps. One is an r32 GTR and the other is an r33 GTST RB25.

So far pricing is on a case by case basis as I'm insisting on doing the installation myself or atleast controlling it due to the nature of the setup not really having been done before.

Bracket, balancer, and drive kit are identical to dry dump parts. Sump is a modified version on my normal 9L sump, pump is a two stage and the surge tank is obviously custom.

Send me a email if your keen to get a quote and have one done.

Sorry to revive this excellent thread but one quick question

Is it still necessary to enlarge the block oil returns and restrict the block feed orifices when running dry sump setup?

Obviously enlarged returns will benefit no matter but if the engine is already assembled then how much off a disadvantage will it be on dry sump setup?

Thanks

I'd also like to know this.

Do I still need to run the restrictors in the block? Or will the vacuum in the engine be enough to suck the oil back down without any issues with the bigger head feeds.

I shot you an email also brad, haven't heard back yet, I understand your busy! see if you could look out for it. keen to get this sorted asap.

Also, I have seen many circuit cars run -12 and -10 lines for the dry sump, and then many run -12 and -16 lines.

Is it wrong to run the smaller lines? can it cause issues? or will it all work to an extent?

hey, being a noob to dry sump etc, the one thing i havent seen on here is where the pressure line is fed back into the block? doe it run through a cooler and into the block via the filter port???, and wat do u do with the stock pump? take the gears out and block it up or something like that? any info would be much appreciated

Theres another thread?

Referring the thread to Risking (Pro Fabrication) and why the previous poster should probably reconsider pursuing this avenue.

Edit: nm - beaten to it

      People still have Skylines? I thought they're non-existent now.

      George's R33 GTST build

      Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.

      They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.

      I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
