ok i have a 93 civic ex coupe with drum brakes, so now i want to convert them to discs. the question is will a setup off a 90-93 acura integra bolt right in and would i be able to use my civic suspension with the integra parts? i got a good deal on a few integras to dig in to, so i just need to know if it really is a good deal. thanks again for any help...

I think 94-01 Integras would be your solution.

94-01 teg rears are complete bolt on's with no modifications

you need the trailing arms, lower control arms, and complete brake assembly

damn that is what i thought. so 90-93 tegs would not work? how much work would go into making the 90-93 teg conversion work? my current set up consist of stock shocks and megan coilovers, and k-sport rear lower control arms. i want to keep this setup since i like the way it is.

i just got a 95 civic and was wondering about this conversion because i have a 91 teg that got fuck by a drunk driver... i was hoping that i could swap those parts right on, but in my research so far say 94+ tegs will work... does anyone know what can be done to get the 91 disc to work or is it not worth the effort.

jay-- i hope im not hijacking your thread.

not worth the effort. a full conversion can be had for 200 bucks if you look around.

call up a couple local junkyards and bet you can find one with everything you need.

94-01 rear setup. see snoopys post above for exactly the parts you need

im just trying to save money... and im cheap.. would the 91 brake system. with the 94+ arms work? idk i guess i should look at the factory diagrams.

I have a 1995 Civic EX coupe, and have done this rear disc conversion twice. The first time was a set of GSR rear discs, and the second was the DC2 ITR 5 lug.

The best way to go is use the full rear trailing arm assembly with rear discs already installed. I know for a fact that the 92-00 EG/EJ/EK Civics and 94-01 DC Integras have the exact same trailing arms. The ones with the discs are all the Integras, the 92-95 Civic Si EG hatch, the 93-97 Del Sol Si/Del Sol VTEC, and the 99-00 Civic Si coupe. JDM rear disc brakes of the previously listed cars are no different. They all have 9 inch rear rotors and 4 x 100 lug patterns. The only excpetion is the DC2/EK9 ITR/CTR 5 lug with 10 inch rear rotors and 5 x 114.3 lug pattern.

Between all those, most of them come with lower control arms with the provisions to add a rear swaybar. Some of the 92-95 Civics with rear discs had lower control arms that DID NOT have provisions to add a rear swaybar.

You will also need the e-brake cables associated with those rear discs. You cannot use your existing rear drum e-brake cables. Since each of the rear disc Hondas have different wheelbases and chassis configurations, go with the e-brake cables for the 92-95 Civic coupe or sedan w/rear discs. 94-01 DC Integra e-brake cables will also work.

The installation process is very straightforward. If you don't have one, invest in a Helm's service manual from www.helminc.com.

Disconnect the e-brake cable, disconnect the brake line, unbolt the strut mount and possible sway bar mounts, unbolt the upper and lower control arms, unbolt the toe adjustment bolt (the forwardmost bolt of the trailing arm), and lastly unbolt the two bolts for the trailing arm pivot bushing (forward of the wheelwell). For the e-brake cables, you will have to drop the exhaust B-pipe to get access. You will also have to remove the center console between the seats to get to the e-brake cable connection.

Installation is the exact opposite of removal. When you install the new e-brake cable, make sure that you fully loosen the adjustment between the seats. Once the brakes are fully installed, then tighten the adjustment so the brakes begin to engage at the 3rd click of the e-brake handle.

Next you will need to refill and bleed the brake fluid. But before you do, I HIGHLY RECOMMEND that you upgrade the master cylinder/brake booster combo, as well as the brake proportioning valve. Your existing 13/16" master cylinder will only last for so long with the new rear discs. When it fails, your brakes will fail, and the pedal will travel to the floor. You will need the larger master cylinder and brake booster combo from a Honda with rear discs. The easiest one to use is the 15/16" one from the 94-01 Integra RS WITHOUT ABS. Your brake line fittings will directly line up with no problems. If you go with any other master cylinder and brake booster from a car that HAD ABS, then your existing brake lines will need to be rebent, cut, and reflared to line up.

As far as the brake proportioning valve goes, the best choice is the one from the 92-95 Civic Si EG hatch with rear discs. It is a direct drop in replacement. The valve is located directly behind the intake manifold on the firewall. If you don't change the prop valve, then your new rear discs will lock up easier.

When you are working with brake line fittings, they all are 10mm nuts. But don't use a regular 10mm box wrench. Instead, use a 10mm flare nut wrench. That will prevent the nut from getting rounded.

Once all is installed, then fill the brake fluid, bleed in the proper sequence (LR, RF, RR, LF) per the manual, and check for leaks.

what about converting a 94 dx rear to disc?
