well my master cylinder is fucked up on my 94 ex coupe non abs , my freind gave me one from a 93 civic dx , they look the same but the booster is smaller on the dx , will boster fit on my fire wall from dx? and does it really matter can i just swap the dx master cylinder/bosster on to my car , im really just trying to swap master cylinders , please let me know wat u think

 

no one

 

bump

 

Dont quote me but if the hard line input spots into the Master are the same and both Non Abs it should work.. Another tip i would do is bench bleed the new one soo little air in the system when you put it in which= Less bleeding.

 

any one else

 

The ex has a larger mc then the dx .

part number for ex
46100-sr3-913
part number for dx
46100-sr3-003
will it bolt up and work yes does it move enough volume of fluid for the larger brake system on your ex no. When it comes to the brake system just buy a reman unit there is no reason not to.
