well i'm getting everything done , Forged Rods + Pistons and ACL bearings all round . N1 Oil pump + N1 water pump and full head work done .. so im expecting around 300rwkw+ with the turbo + Fuel setup that i have .. I give the car alot of hell , hence why my last motor blew up due to seized bearing or whatever made my rod fly out the side of block .. I just dont wanna have any oil issues with the car and was wondering is the Spool Hi Energy sump too much for what im doing and does it really help with the rb25 oil issues .. also i am fitting the tomei oil oriphis or watever they are called into the head

I agree. Drop the N1 pump too and buy a JUN or something better with the money you'll save, and run the 1.5mm restrictor/block off plug setup as per sydney kids recommendonations.

If your overly concerned about oil surge on the street because of how you give the car hell, then run the oil level a tad above the high line. Problem solved.

if you're just doing street work there may be some baffle kit for the sump?

i have a sump baffle and an oil restrictor on my GTR when i had my engine rebuilt.

it works well for the street.

and if you're not tracking the car, then i doubt you'd really need to be sitting on the rev limiter when driving it on the street.

Waste of money.

N1 pump is fine.

Stock sump is also fine.

If you are worried, just overfill by 500ml for a RB25. As long as the head/restrictors are done correctly in a street car you don't need to go all stupid on parts.

Especailly not for 300rwkw.

Im buying billet gears for my stock oil pump...should solve durability issues as even the N1 pump still runs sintered steel for the gears, which is prone to cracking, the best part is the billet gears cost a lot less than the high end pumps but should be just as strong

if the motor is out then y not do it anyway???

what if in 6 months he suddenly decideds he wants to take it racing abit.

may aswell do it now n save on labour in the future.

I can play that game as well... What if he doesn't go circuit racing? Pointless mod.

Even with 300rwkw @ the circuit - Your "average" 350rwkw GTR with 4wd and semi's comp's doesnt use sump baffling...

Now given they will have more traction and g-force than a 300rwkw gts-t will ever have...

I cannot see a baffled sump being of much use.

More beers @ the pub for him basically, signifigantly more infact.

The fact he "gives his car hell" and threw a rod would be more about limiter abuse and poor maintenance... none of which a super sump is going to stop at all.

fit std pump and std water pump, more than adequate.

We used a std RB26 sump with removed diff and a tomei baffle only. With a greddy pump (60l per min) we had no issues for 3 years, we "upgraded" to a bigger baffled sump from a reputable engine builder and it cost us two engines (independently inspected).... swapped to an ASR and all the dramas are over.

point of story, you dont need one but if you do the only after market RWD sump we use now is the ASR (high energy) item.

Was it a properly built motor, with 300rwkw, as per the nature of this thread?

But then, all you NSW people seem to suffer from SBS.

Stock motor at 250RWKW...

And it spat it off throttle. When I picked the throttle up it was all over.

And that's because NSW has real race tracks... Or did... :D Oran Park ate mine going through the dip before the bridge...

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
