RB20DET, Stock turbo 15psi 164rwkw

City: 470km's per ~50litres. That is until the red light first shows.

Open Road: Not sure have never taken it on a full tank.

WOT: Booting it the RB20DET would drop fuel economy to low 400's per tank.

Driving style didn't appear to make much difference to fuel economy.

RB30DET - Stock rb20det turbo 176rwkw 9psi.

City: 450km's per 50litres.

Open Road: Again. Not sure.

WOT: Booting it the RB30DET drops to 380km's per tank.

I'm scared to start swapping out the stock injectors incase fuel economy goes to the sh*t. :D

Mind you Bl4ck32 has 550cc rx7 injectors thats all been tuned up, his rb30det in his r32 tends to get slightly better fuel economy than mine.

ive found a trend in my car. it's basically always KMs/10 + 10 = Litres of fuel

so 350kms = 45L filled up

400km = 50L filled up ... and so on

my 33's usage was similar

so far ive only had one tank which was used for pure thrashing and i did about 250km in 55Ls :D

freeway driving is typically a lot better than the formula above.. the other day after filling up, i drove 130kms. then i pulled over and filled it up again, and i only put in 16Ls..

edit: i just realised that the above does not apply to u as i have an rb25det in my 32.. lol sorry.

Hiya,

I've got an R32 GTS-t manual and I get roughly 380-400km out of the tank of regular city/suburban driving.

just did a drive up to Sydney and back a few weeks ago before that dreaded fuel increase and estimated with general cruising averaging 115-120km/h I could get around 600km to the tank.

Mind you though the car's running an aftermarket replacement ECU and it doesn't run an airflow metre anymore so I was expecting it to drink more than that... :)

Fuel tanks get a build up of crap over the years. A friend of mine had a vl turbo that used to run really rough whenever the fuel gauge went below 1/4. Thats the worst I've ever seen.

You could fix it by taking the fuel tank out and cleaning it out, but that is just sooooo much effort, much easier to just keep a nice amount of fuel in there. :)

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.

      I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things

      I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt

      So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm.

      Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
