ok i got a 94 civic hatch with b16 front brakes and im puttin gsr rear discs on it.. now i have herd u can use the stock master cylinder but then i hear it better to use the gsr one and the gsr proport valve.. and sugestions???

 

wtf are "b16" brakes?????
all 94+ integras (non-r) have the same brakes (gsr is not special)

this topic has been beaten to death, i suggest you do some research on the topic by searching.

You dont have to change either mc or prop btw...its recommended by some, but not required

 

b16 disc brakes like a 2000si they bigger then the stock cx brakes that came on the car.. and so yeah i ahve to get new master cylinder

 

Yeah those are ex/si brakes (meaning the si brakes arent special either)

if youre using those, you should have upgraded to the 7/8" mc already...which you could get away with using.
You cant just use an integra mc without the booster as well - you can use a 91 civic ex sedan mc w/o swapping boosters though

again, you need to do Research not just ask questions that have already been answered again and again

 

well thats what forums are for cool guy is too ask ?

but thanks for the info

 

not if its been covered 10000 times before - its why there is a FAQ thread at the top of the forum "cool guy"

and youre welcome
