Hello ,
i want to make the rear disc conversion on my EJ1.
I have the rear trailing arms from an Civic Vti. The seller gaved me 2 trailing arms , a sway bar , brake booster , 13/16 master cylinder and 30/30 prop valve.

On my car, 1993 Civic Ex , i have installed a 7/8 master cylinder and a 30/30 prop valve. On front , i have 10.3" rotors , stock calipers.

1. I want to ask u guys , which master cylinder i should use now, 7/8 or 15/16?? Which one is the best for my setup?
2. I need the 40/40 prop valve , or i can use my 30/30 ?
3. And , is there a difference betwen my stock brake booster and the VTi ones?

Thank u very much and hope to get ur answer soon , so i will be able to start the conversion.

LE : I already purchased a 4040 pv from ebay and trailing arms bushings

 

Some info , pls?

 

use the 15/16's or 1" from an itr, 15/16's works best
40/40 prop valve
i don't know what size the VTi is, but bigger is usually better. I upgraded to a bigger one when i did mine.

there's more info about EJ1's on ej1oc.com if your interested. Forum dedicated to EJ1/2's

 

Tks , ill search more , because this is very confusing..
