Fuel economy of an RB20DET?

[den_iel]

What's the fuel economy like for the RB20DET stock?

What about when it's modified to around 200rwkw?

I've got just on 200 rwkw.

It uses around 15 litres per 100km around town without getting on boost all the time and around 10l/100km on the Freeway at 120kmph.

Under 120 in fifth it actually uses more juice trying to push the turbo and is really hard to keep at constant speed.

She loves 140kph or 4000rpm.

Last track attack at Wakefield I used 20 litres for 65 km.

I've got stock injectors, AFM and regulator but GTR fuel pump and APEX piggy backs.
