the one for the 91 EX sedan bolts right up to your booster and is 15/16ths (as opposed to your 13/16ths one now)
if your booster is going out as well you may want to upgrade to a non-ABS integra booster and MC... you will also get the 15/16ths MC but you also get the higher volume booster... this requires some modification to the lines

So i should get the 91 EX booster and MC?? will i have to modify the lines on this one?

you can use your stock booster with the 91 EX MC
everything i have read says that you do not need to modify the lines for this MC

i have not done this (for mine i went with an ITR 1" MC and booster and adjusted the lines as needed )

if your booster is shot you can replace it with a stock one for your 93 Si and put on the 91 EX MC (you might be able to use the 91 EX booster... i dont know that they are any different)... or you can go with the integra booster and MC
