My RB30DET that runs the rb25 head gets 430-500km's per tank.

The odd trip up to my oldies that takes 20mins each way on the freeway bumps fuel consumption up close to 500km's per tank.

The usual city & local 60km/h driving is always 430.

Should pick up a bit of fuel consumption once the bigger turbo is on as the stocker is always on boost.

The RB20DET used to get a minimum of 470km/s per tank but being a little laggy (3500rpm = 1bar on stock turbo) it really wasn't on boost like the rb30 is.

A friends R33 RB25DET that was making 175rwkw running the usual exhaust, fmic & 11psi used to get close to 500km's per tank. It appeared at the time to be slightly better than the rb20det.

Drove to Toowoomba the other Sunday. 42litres for 436km=9.5l/100k's

Normal highway driving except for the big pull at the end. (210rwkw)

You guys with 200k's per tank are asking for a vehicle inspection. Cops aren't dumb and all that black soot around the bumper is a dead give away.

Regards.

    • 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?
    • 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
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
