Hesitantly Boosting
stagea's are based on the r33 version of the RB20/25, with the r34 i believe they would of made some slight alterations to the motor and it's overall characteristics, not mention the NEO RB is a whole different kettle of fish.
I've owned a *insert Nissan wagon name here* with a later Neo RB and fuel economy was pretty insane for what it was. Although mine was the RS-V model, meaning RWD only, meaning better fuel economy than the AWD version.
