as above, 2.0i glt uses almost the amount of fuel what my s14 does! thought it'll be a more economic car to own

Doesn't surprise me... and if you think of it, why would it use any less? It's a 2.0 8v running on 80's fuel injection.

Welcome by the way

I used to own a turbo s13, ecenomical when driven slow, but at track days i could drain a tank in under 200ks, and did it in under 300ks on the road a few times, the 360 i had did 11 or 12L/100ks not matter how hard you drove the thing.

User's manual of my 360 promises fuel consumption under 6L/100km which is less than 39.2MPG, that is if you drive 90, but even when driving 80 and less it seem to have trouble getting under 10L/100km (23MPG), I believe that with well tuned MS setup that should go to more human numbers when driven gently, but who can drive gently with car that has very good throttle response?

Yeah, these B200 engines were never really meant to be economical sadly. I'm sure my 360 is getting slightly better MPG then my old pair of 740s (with the same engine) but i'm putting that down to a somewhat lighter bodyshell, and the fact that I dont do as many round-town miles.
