Quick cut and paste;

The oil drain from a turbo operates via gravity. That is, the pressure drop across the turbo bearing is nearly complete and it is only gravity that causes the oil to flow back to the sump. In fact, it cannot really be termed ‘oil’ as after it has passed through the turbo, the oil becomes an aerated foam – one reference suggests it looks like ‘dirty whipped cream’. It’s therefore important that:

  • The drain line is much larger in diameter than the pressure feed line
  • The connection to the sump is made above the oil level
  • The drain pipe is kept as close to vertical as possible

If the sump drain joins at a level below the oil, the much lower density of the aerated oil will cause it to sit on top of the sump oil, gradually backing-up to the turbo.

I use the original High Energy design of sump with the square front. I don't like the sloping front design as under brakes the oil surges up the slope like a launching ramp. Then #1 and #2 big ends splash through it on crank rotation, this foams up the oil which is never a good thing. With the square front there is no slope fo the oil to run up, it hits the 90 degree wall and stays below the splash screen.

The resason for the slope is to clear the standard swaybar. But let's face it, if your car needs a HE sump then it sure as hell needs a bigger front swaybar than standard. If you already have an upgraded swaybar then they are an easy sell, with that money you can buy one designed to clear the sump.

Very interesting.. where would one get one of these aforementioned swaybars?

Whiteline only sell catalogued part numbers, so they don't have one. I don't think KMac have a design, but you might want to check with them. I do know Selbys Swaybars definitely have a design for R32/33/34 with HE sumps because I did it while I was there. Plus I have one on my R32GTST.

Gary - i've edited your thread.

Considering you dont respond to PM's (one i sent about your trading 6-8months ago), and have a very poor record of trading/resonding with numerous complaints in the last 12 months.

You are no longer able to trade on SAU after you're 'break' from SAU... even if you've been posted on IPRA forums constantly.

Discussion will not be entered into, and i suggest all users thing carefully about engaging in any dealings.

Feel lucky that you were not banned.

Thanks.

well just thought id put up that i got my high energy oil pan (long wait but not in hurry) very nice work, clean work and gates move freely, highly recomended, just a question for asr oil pans if he come on much, how come there are two different designs of oil pans between the just jap ones and the ones sourced through et performance products? i know the et ones are 8.5 ltrs and the just jap ones are 6.5, but why the different design?

lewis engines are my choice. they are local but that's not my reason. darren told me the drift sumps @ $399 have baffling etc and the circuit sumps at $599 have a one way corridor and extra baffling etc all the sumps fit no worries, including rb's in to silvia etc.

Sorry All, Haven't had time to get on the comp.

There is NO physical external difference between the Just Jap pans and the ET Perf.(High Energy) pans.

As I have previously stated, We make both ASR and HE pans.

I think you might be comparing a Race pan with our Street pans (S/S or S/C), two completely different designs for different applications. The Street pans are the entry level pans designed for street use (6.5 Litre capacity). The race version is obviously designed for racing (8.5 Litre capacity).

The only difference between ASR and HE is the internals.

The ASR pans are generally more complex and contain more, as we update our designs.

The capacity of all the oilpans is engraved next to the Drain plug on all ASR and High Energy oilpans, along with a serial number that corresponds only to our work history logs. That will tell us: When it was built, What it is and Who it was for, as we do pans for many other Suppliers/Speed Shops.

If anyone would like to query a serial number of any ASR or HE pan they have feel free to email [email protected].

Thanks

Ben

    • I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car
    • Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.
    • I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it
    • If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣
    • I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
