gsr/itr

 

Really? I thought the GSR carried the 15/16ths and didn't know the ITR.

 

My Hybrid has the 1" master.... hehehe.

kidding aside...
ITR/GSR has the 1 inch. The brakes on my EG are all from a GSR.

 

The GSR if it has ABS. I got mine from a 97 GSR with ABS and it is 1 inch. But it uses a funky fitting on the outlet next to the booster. So I had to reflare the different fitting onto my stock hardline.

 

R and LS I believe.

 

ITR and GSR both have 1"
RS is 15/16th

 

Do a search, I believe I saw B18C1-EH2 posted something about a civic having a 15/16th master cylinder that will bolt up to the booster. I'd search but I'm lazy

 

what do civics have? just outta curiousity.... i wanna know how much of an upgrade this would be.

 

My '92 Si has a 13/16" master cylinder. As Tom mentioned in a previous thread, the 1991 Civic EX 4-door (non ABS) master cylinder is 15/16" and will bolt right up to the 5G booster. P/N for that is 46100-SH4-A11.

 

whoa whoa whoa ..your si cannot have a 13/16ths
re check it and let me know ..

 

hope this helps...i think they use a 1" from an ABS integra (like people have already posted) http://tech.hybridgarage.com/tech/brake2.html
