Running no booster, need room for turbo.

true a hydro booster that runs off the power stearing is used on most newer "heavy duty" full size pickups

the disadvantage of this setup is that it makes them hard to steer in tight places like parking lots, however could be overcame by bigger ps pump and may not even be a prob in something as light as a 620

also provides more braking power than vacuum

another option is a big bore racing master cylinder and no booster however this can be expensive (as if hydro boost isn't)

IMHO In a non boosted system going to a larger m/c will increase the effort needed to work the brakes. You can't get something for nothing. You would have more volume, true, but you would have to expend more effort to move it.
