I love what you have done to your car and engine. I'm actually considering doing the same at the moment, although I was thinking of getting a GTS25t, selling the turbo motor, and then going n/a. That way you have the turbo brakes, fuel pump etc and the cash from the motor. This only makes sense to me because I really want an RB30DE. Just an idea... anyway the point of this post was to ask:
What is your average fuel economy with the RB30DE in Litres/100km?
Thanks mate Looking forward to following the progress of your car
