Yes, it sounds like you have the plumbing reversed, there may be an F or R on the cylinder, match up accordingly.
Search here or on Google regarding the "Lumpectomy" on the Miata seats, it'll take an inch out of the height.

Re: Yet another SR20DET Swap-66
I posted this reply to your question-- perhaps you did not see it:
The Front Brakes get plumbed to the reservoir closest to the firewall, the Rear Brakes to the outside reservoir. Many master cylinders have a F and R cast into them to prevent a mix-up!

Re: Yet another SR20DET Swap-66
OK swapped the brake lines and now have rear brakes. I wouldn't say the brakes are outstanding even with 300ZX fronts and Ford rear disks. But they'll do. I can lock them up if I push hard enough.
Cleaning up some wiring and starting to look at interior.
Anybody have ideas on the convertible top frame resto. I was trying to avoid drilling the rivets to blast and paint (or powdercoat). I figured some ceramic chassis black would work if I was careful around the joints. Thoughts?
Regards,
Steve

Re: Yet another SR20DET Swap-66
I painted mine, no problems with the joints/rivets. Of course I rarely, rarely ever use the top.

You might search changing the pedal ratio.SABLT194 wrote:OK swapped the brake lines and now have rear brakes. I wouldn't say the brakes are outstanding even with 300ZX fronts and Ford rear disks. But they'll do. I can lock them up if I push hard enough.

Re: Yet another SR20DET Swap-66
Good idea Phil. I'll probably drop from 7/8 bore MC to a 3/4 bore first. That should improve my pedal feeel by a factor of 1.35 and still wouldn't stress my firewall and more. If I need even more, I'll start the pedal ratio changes.
