Actually a mate of mine went that route, but a 1 inch boost + BMC from VTIR, and fitted all fine so again, my point still stands, booster and MC, went we fitted all the lines, from his ek it fitted fine, no flaring of any lines....
AND as far as im aware, from all the web sites on Honda-tech, d-series.org etc etc..
Brake Booster
Upgrading your brake booster to the Integra (or maybe other) sized one has the only drawback of pushing the MC forward, so the hardlines aren't going to be in the same place as they were. So bending hardlines may be in order. What a bigger booster does is the same thing as increasing the pedal length, it increases the force on the MC linearly. Like it may may push on it 40% harder or so at any given point. So this basically makes your foot do less work. This is for people who have a really soft foot and want to make their car brake 'harder'. This can be done, but given the weight of the civic chassis, if you use the right sized MC with its paired caliper, no upgrade to the booster is necessary. It gets to the point where its just personal preference.
