after reading through these replies, sounds like I need r32 master cyl, which brings up a new dilema for me. I'm in the US. We never got Skyline here in the states until now with the R35. That said, me getting my hands on a r32 booster is going to very difficult.[/QUOTE]

you can also try and source an s13/14 brake booster. im using an s14 at the moment with fc upgrade and it works well. my bro is using the s13 but hasnt got his car running yet. both of them fit tight with no problems.
