you need to do some more research, there is more than to building a turbo engine than just bore size.

stock bore, mayb cut in to it by .25 or .50. I dont think going
to 84 or 85 mm bore is a good idea, crazy sleeper, even in an
NA setup, but i would think that with all the pressures, a miss shift
or bad tuning will break through them. Unless your gonna pay the
money for ductile iron "godzilla" sleeves from Golden Eagle.
Then i'm sure you can throw just about anything at the motor.

1mm over is the max i would bore a stock sleeved honda engine.
In order to go 84mm and have a 1.6L you would definately need to sleeve the engine.
The stock bore is 81mm for the b16, b18a/b/c/c1/c5.
