so what weights are good for rb25det? lowest possible and then 40 weight? or is 30 or 50 better for an engine with around 80 000k

Try a 40wt first, if no oil consumption then try something lower like a synthetic 10w30

I'm work as a aircraft mechanic as my day job and import/supply performance lub to local clubs as a sideline/hobbies.

Motul 8100 5w40 may not contain ester in it's oil formulation. You may want to choose 8100 0w40 if it's ester you are looking for .

Yes, Delvac 1 5w40 are fully synthetic using a blend of PAO/ester couple with a pretty strong additives pack and it's cheap too over in Aussie.

Another good read about polyolester.

polyolester - redline oil

Just curious Trex if you say they are cheap in Australia, would you know where abouts i can get my hands on one? retailer in sydney perhaps?

Will using delvac 1 be safe for changing oil every 5000kms everytime?

      Is the CD009 similar length from bell to shifter?    car will just be for the street with the odd track day. It’s RB30det, and weighs about 1000kg

      The r34 gearbox is like $3400/3700 landed from Japan sometime last year.   Contact jessestreeter.com for info and quotes. From memory the navara gearbox needs input shaft machined down as I looked into a while back and there's a thread somewhere here from 2018-2021 about it. Depends on what your doing with the car maybe worth the dollars to go cd009 or a 8hp50/70.

      VCAM doesn't really increase peak power, it just widens the powerband. So if you were giving up power with adjustable cam gears to get better low-end response yes in theory it "increases power" but otherwise not really. Stroker kit might put you in a more efficient region of the compressor map which will get you more power but at say 7000 rpm I'm not sure that much will change. The original HKS GT2530, -5s, and GTX2860R gen 2 are all roughly the same kind of turbo. If you want 600 horsepower those are the turbos you need. So 500 whp. Just expect to spend some quality time trying to figure out intake/exhaust piping. The "twin turbo" pipe is an obvious place to start. Make sure the actuator preload and all of that fun boring stuff is set up correctly. Throw a VCAM step 2 at it if you want good response, 2.8L stroker too. If you're not actually wedded to 500 whp all the time you can barely get there with -7s or Nismo R3 turbos, you just have to run E85 or race gas and run them hard:
