S13/Z32 BMC Measurements

[asoomal]

Hello,

I've searched online for the brake master cylinder dimensions for an S13 and a Z32, but I was unable to find anything.

I don't have a BMC for those two vehicles on hand, so I'm unable to take my own measurements.

Does anyone know what the distance is between the mounting holes on the flange of the BMC?

Also, the total length? From the flange to the front end of the master cylinder.

Thanks!

Yeah that would be good to have. The mounting flange should be the same, but the overall length, width, and outputs for the lines (spacing) are probably a little different.

Flange bolt hole spacing is 80mm center to center (8.7mmØ bolt holes). Center OD that goes into the brake booster is Ø40mm. Back of mounting Flange (where it rests against the brake booster) to the very front surface of the master cylinder is 152mm in total length. From That surface to the first brake line hole is ~51mm (It's at an angle) to center. Back of flange to second brake fitting hole is 70mm. Back of flange to third brake fitting is 106mm. All length measurements are ±1mm. Ø Measurements are ±.1mm. Looking from the side of the master cylinder, the brake fittings are about 10mm above the bore center line. Looking from the bottom (or top) the perpendicular brake line hole faces are about 43mm from center line. The inner most angled one is close to center line a bit.

All measurements are taken from an OEM Nissan (Made by Nabco) 1" Z32 Master Cylinder. Hope that helps. I don't have an S13 master cylinder handy to measure, but it's a direct swap. The S14 one is very different (I have one of those if needed).

Thanks!

It's not going on a 240SX, I'm trying to size out a MC for my GC Impreza.

Anddd it looks like it will work!

Thanks a lot!

Not a problem!
