Hi guys and gals..... I am preparing my GTR for circuit racing and need to replace my sump with one with a larger oil capacity and better baffled. I came across one manufactured by GREX at NENGUN performance parts (nengun.com) but no details such as the sump's oil capacity and whether it sits lower than the original sump.

Does anyone out there have any info or can refer me to someone who does?

:)

Hi.

The TRUST / GREX sump does hang lower. According to an engineer mate of mine who does a lot of V8 Supercar work, you cannot go past the Jun sump kit (baffle kit) for light circuit racing.

Good luck.

Powerplay in Sydney got hold of the Trust Sump kit for my race car, it includes a sump extension you weld in, a new oil pickup and some additional baffles.

I thought it was 8l not 10l though, the 10l might have included an oil cooler?

Merli has also just fitted the Trust extension kit. It seems like a great option when compared to the price of the baffle only kit from Jun and Tomei. Increased oil capacity, baffles and modified pickup.

Nengun and Greeline can supply these, alternatively if you want to buy from a local store im sure Advan in silverwater has them in stock

Sorry to bring up a reasonably dead thread but has neone actually used one of these kits on the track and to what degree of success was experienced, i just purchased one of these kits (the grex) and it is waiting to be installed on the car. Its the kit with extension oil pickup and extra baffles, is this kit sufficient to eliminate the common oil starvation problems GTRs face when at the track when used in combination with a good quality oil cooler.

Cheers

haha yes, race car has done a heap of track days over 12 months. It seems to be a well designed kit, and no doubt just the extra capacity on its own is a help.

We also run restrictors in the oil feed to the head, and I have heard of people using baffles or foam in the head as well.

Yes the R31 N1 has an oil cooler although no filter relocation kit, so total oil capacity is up another litre or so, up to about 8 litres from memory

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
