Oil starvation solution for RB engines.

A product worth looking into if you go to the track. RB motors are notorious for oil surge and starvation problems at the track. Saves putting a sump baffle although this would still be a good idea. A cheap option for high performance road or track car. Check out www.accusmp.com and this shows how it works http://www.accusump.com/acc_tech_diagrams.html I put one of the smaller ones in my zed race car recently. We also moded the sump to prevent oil falling out of the the bottom of the sump under g 's as an extra and also stops oil foaming up by the crank by thrashing the oil around. Although Zeds don't normally have oil starvation probs.

Bottom line is they keep constant oil pressure when oil pressure drops from oil starvation from harsh braking, accelerating and cornering, as oil in the bottom of the sump comes out and you have oil starvation problems. It is an alternative to pulling the motor out and putting sump baffle in, or can be used in conjunction with this and oil restrictors to the head. So if you are concerned about hitting the track and don't want to spend thousands pulling motor out and putting sump baffle consider this option. May also be a better option than a sump baffle. You can buy them direct from USA companies or we can supply them for around $400 to $500 Morroso brand. Plus - 10 braided hose and connections including T piece into the oil cooler line. Prob extra $150 to $200. Simple and easy to install.

Hopefully get a few more of you guys out to the track with us and off the streets. I am sure you would like to beat my zed.

Don't know how long it lasts but at 7000rpm or more it only needs a very short time to do damage. You would need to have a passenger and watch the oil pressure guage I guess and even then may not be a accurate indication of very short time of oil starvation as there is a delay. Fitting one in a GTR engine bay may be difficult. Might fit though or may need a hole saw, or put in the boot and just run a line under the car. It only uses one line as it does not circulate the oil.

Also see the thread "Accusump vs Sump Mods" in the Forced Induction Forum.

I fitted an Accusump to my GTR and as you say finding a place to put it is a little difficult. We ended up mounting it inside the front bumper - just needed a slight modification. We had looked at plenty of other placed but were always mindful of a) keeping it outside the car - didn't want even the slightest chance of bursting and sending hot oil all over anyone, and B) keeping it as close to the engine as possible to maintain pressure.

I've run mine on the track since and have had no problems with it or oil pressure.

Maybe not as good as a full sump mod, but certainly a lot better than nothing at all.

      Clutch done also about a year ago got a DCS HD Single Plate. Basically done everything but touch the engine 🤣 But will definitely get a fuel pump and ECU, then start saving 🫡

      Fuel pump and clutch and ecu that’ll get you to about 230 or so kw, after that the sky’s the limit and the budget blows out faster then you can blink

      Should add all mods on the car are done in my ownership. The car was a 1 owner in Japan and I'm first owner in Aus.

      Thanks GTSBoy. Did BC's so not Japanese coilovers. I've already done all the other points you mentioned besides the seat, I like the factory seats and want to keep original look. Done all the fluids and comp tests etc and all consistent and clean. Well and truly used to the power and car as I've been driving it for a few years as it is now. Contemplating next steps mainly. Preference to remain twins too. @Murray_Calavera Paying for labour.

      Hmm. I don't think it is possible. As soon as you start, you will be on the hook for all the money. $5-10k is enough to make it fragile. Here's the list of things you need to do to make it nice, and driveable. If Japanese coilovers, get them measured and tested, then decide if you're keeping them or replacing them. If low rate springs, then consider big ARBs. If high rate springs, then probably leave stock ARBs. Either way, ad decent end links. Replace and/or upgrade all suspension bushes. That's LCAs front and rear, UCAs & traction arms at rear, caster rods at front. I highly recommend GKTech FUCAs, although the step to spherical joints is a step too far for some people. Rebuild brakes front and rear. This means making sure the calipers are healthy, discs are up to thickness, hoses are replaced with braided. Add good pads and fluid. Investigate wheel bearings all the way around, tie rod ends all the way around, upright bearings at the front, balljoints everywhere. Any of these that are still original are likely to be a bit wibbly nowadays. Bride or Recaro driver's seat, with fairly deep sides. Nice tyres. Street performance wheel alignment. Or track focused, if you're not going to use it on the road. Fluids everywhere if not known to be fresh. Now, learn to drive the car as hard as it will go, before trying to add any power. Save up big $$. $5k is the minimum cost for putting a decent ECU into it. A big single, with manifold, new exhaust, injectors, fuel system upgrade, ignition upgrade, triggering upgrade, etc, is >>$10k. None of that (except the ECU) is a good idea on an old RB. You really should put head studs in it, investigate engine health (compression and leak down, real oil pressure at revs, coolant condition, etc) before even considering adding power. There's nothing sadder than the "I added boost then it shat the bed" thread.
