hey guys i have a 98 b20b swapped in my civic, bone stock, and i fill up strictly 91 oct and im averaging about 300km a tank, driving hard sometimes but not much, is this normal?

1) don't use 91 octane, use 87
2) With a b20 swap, there is no stock basemap you can use that will run perfectly, since there are no b20 basemap available. You need a custom tune to have optimum fuel economy.

91 burns quicker than 87. You will get better fuel economy if you use lower octane gas. Also have you done a tune up? Such as plugs/fuel filter/o2 sensor? Things like that will benefit to your high gas consumption if they are failing.
Also what ecu are you running?

Injector cleaner, 87 Octane, Air Filter, and possibly Plugs are all good culprits.
