Hello again

 

I'm about to drop my freshly built motor in and would like to know what oil to use to break the engine in and what oil to use after and what sort of mileage should I use the break in oil for before changing...

Some specs

Forged internals

Forward facing plenum

Gt35 garret turbo on high mount

800cc injectors

Nistune to be tuned

Brand new head

Turbosmart wastegate

Hoping to run 12-15psi

Fuel pressure regulator bla bla bla

All the other bits I can't think of

Hoping to get 400hp from her, would like more but will see how I go.

 

So what sort of oil do you guys think?

Use a mineral oil (not a synthetic). Push it hard without going OTT and watch for overheating and leaks. Do not baby it. Most of the running in should be done on the dyno with the initial tune. Dump the oil and keep using mineral oil for the first 10,000 and then switch to a quality synthetic.

      Hi GTSBoy, Excuse my ignorance but what does a "Bad" Knee point mean ?

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      R34 25GT Engine Light 21

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
