If i end up keeping my running gear i will enlarge and improve the sump oil capacity and anti-surge characteristics. The 4WD sump has already been installed with a boxed pickup at the bottom, which then taps into the RB30 block from the outside where the old oil-pickup used to be, this is due to the sump blocking the RB30 oil pickup. The engine is going into an R32 GTR and i want to know what i can do do improve on this. I already have an oil cooler so the oil capacity will be slightly increased but im sure other things can be done aswell

Thanks for your help

Road and maybe drag

You won't generate enough G-forces on the road to need anything better than what you have. If you are running water cooled turbo/turbos, an oil cooler is probably not necessary either.

If you are intending to use road tyres for the drags you won't need anything better than a standard sump. For radial drag tyres or slicks the most common sump upgrade we see is the Trust sump extension. This solution would mean redoing the external feed to the pickup.

:D cheers :D

I was doing some surfing around the net and came across this on the high energy website. The sump looks good, still plenty of ground clearance but some extra volume plus trapdoors. It might be worth a look http://www.highenergy.com.au

ProEngines: I just rang Hi-Energy and they said that the sump in your picture was a one off for the owners car and due to "poor casting" that they will not be making anymore.

Maybe Hi-Energy know something all the jap tuning shops dont? I doubt it but thats what they said anyway

Rather than a 'poor casting' it's more likely they had trouble cleaning it or simply didn't clean it properly, which is essential for TIG welding (and to be fair not that simple on a cast alloy sump that's contained oil for many,many years).

acid clean and abrasive blasting should clean it like new

      Borg Warner EFR Series Turbo's V 2.0

      A few things that seem a bit off here. - why is there 2 BOV’s?  - the turbo smart BOV on the compressor housing, is it turned up ALL the way? I have seen this become an issue on old man Pete’s car. It would push open and recirc, turbo speed would rise and the boost pressure would do weird things. - stock head? Does that include springs? - tried a different MAC valve? Is it plumbed correctly?

      Photo of manifold showing gate location? I mean, it's 6Boost, so we probably shouldn't be worrying, but always wroth knowing what the layout is. Plumbed back to atmosphere? Or into the dump?

      Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened.

      Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging. Cheers
