Default rear disc brakes

ok since i don't want to use the 90-93 teg rear disc brakes i want to use the 90-91 crx si one onto my 90-91 civic si...

everything will bolt on correct?

all i need is the 4040 prop from the crx?
Also, do i need the 90-91 crx si ebrake line also? or the 90-91 civic si is the same?

I've did the search bar but everyone did the 90-93 integra

If I'm missing anything please inform me thanks in advance!

p.s... I'm doing the crx si rear dis brakes because i want to keep it EF all the way don't want to put a DA part onto a EF car

these rear brake things are so unclear... i guess the basic rule of thumb is... whatever you get the brakes from, be sure to get all the matching lines, cables, and prop valve?

well good luck finding yourself those si's i used 96 GSR rear disc, they bolt right up and yes you need the si cables the tegs are too long, and you also need a 40/40 valve you can get that off any non-abs DA thats what i just put on my car today..

You know EF and DA are like brothers most of the parts are compatible with each other.

I believe the rotors and calipers from the 90-91 crx si and DA are the same, the only noticeable difference is the rear trailing arm bushing. DA's have a larger diameter bushing.

You would need to use DA e-brake cables because the ones from the crx are too short, and the 4040 prop valve comes from the 90-93 integras.

You can keep your upper and lower control arms, and solid brake fluid lines... i think i'm missing some info

You can use any rear disc from the integra 89-01 and civic 88-00. DA does have the larger trailarm bushing.

Used the CR-X Si parking cable and brake line.

I have a pair of Koni Yellow struts with skunk2 coils from a car I bought at a salvage auction, they were off an EK coupe. Which rear disc conversion should I do that will allow me to use these on the rear? From the looks of it, the EF bushing for the strut mount is wider than the EK.
