Ok, ive been searching the board but nothing concrete has come up. I have a 93 si eg and i keep hearing different brake sizes that are for it?!? The 94-95 has larger ones, etc.

Questions:

What size of Brake Master Cylinder am I running?
Can I swap my discs with 01-03 civic discs off of ex/dx/lx?
Is it worth doing the GSR brake upgrade?

 

its worth it... look in my sig if you want the 1" m/c and booster..
