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.

      Jacks that fit under GTR lips that can reach the subframe?

      By TurboTapin · Posted

      For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      Looking for someone with a R34 front bar

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
