I cannot find the answer I am looking for so..
I have the following brake setup that I will be finishing up here within the next month and I need to gather a few more things before completion. My major question is about the prop. valve. Which is the correct one for the following setup??

1994 Civic DX hatchback

FRONT
11.1 NSX front brake conversion

REAR
Stock rear drum

I am not upgrading to rear disc. I do not feel the need.. just curious what the proper prop valve would be.
Thanks for the help.

 

use your stock one.

since you have drums in the rear, you should keep your drum proportioner



master cylinder

have you considered upgrading your 13/16" master cylinder?

on your 94 civic DX (since you are upgrading to NSX front calipers), you're going to need more fluid to push the larger pistons.

a 15/16" master cylinder from a 90-91 civic EX will bolt up to your master booster assembly; no bending or re-flaring of lines.

I also forgot to add that I am using a 1" ITR MC/BB..
Does that make a difference in proportioning? I already know about the re-flared line and abs fitting needed for making the MC/BB work properly. I researched everything and got all the information that I needed except for which factory prop valve.

 

a 1" ITR mc & brake booster will work nicely with your NSX calipers

again, since you are using drums in the rear, you should stick w the drum proportioner

 

They're not really setup like that. Honda has used identical prop valve on vehicles with and without rear drums. They actually have more to do with what front brakes are used. Try the stock prop valve, see how it works, If you have too much rear bias try a 4040 prop valve fron a '90 - '97 Integra.

 

I might just have to do that. I was hoping I could just find the right one ahead of time..or discuss with someone who has done this identical setup. Most ppl that have done the NSX fronts already have rear disc.. I just do not know very much about Honda prop valves..at all

I will be doing a complete brake flush/drain as well. ATE Super blue will be used in place of the old fluid and once the entire system is bled..I would rather not have to do it again if ya know what I'm saying

Thanks for all the input so far. I really appreciate it
