I think my mc is starting to go out, and the local parts shop doesn't have any in stock. Does anyone know if the 90-91 honda civic's share brake boosters with anything? Or any oem replacements that are a bigger size like a GS-R one that bolts up with no issue? Tried looking through the fourm and all i got was stuff for the Eg's and Ek's

 

what size is your current mc?

 

Your probably best off trying to locate one of the same as what you have for stock on there, going to a bigger one from an Integra may give you a firmer brake pedal but less braking power. I think the master cylinder is to match with what ever your front calipers you have.

 

try eBay. ik it looks sus. but they are the same part as AutoZone.
