Sorry if this is a stupid question, but I've never owned/worked on an SI CRX before. I found a complete stock rear suspension stabilizer / bracket system off a 91 crx si for cheap in a local ad.

I figured it wouldn't hurt to retro-fit it on my 90 DX, especially considering how cheap I could pick it up for.

Would I run into any issues? Are there any differences between the undercarriage or trailing arms of the SI and DX which could create mounting problems?

The part I'm talking about is #7

Tyson has a write-up on this in the FAQs I think... regardless of where they are for sure Google it...

 

no issues. The civic and CRX bars are directly interchangeable.

 

To change to rear discs you will most likely need some other parts. For example: 40/40 brake bias, disc/drum parking brake cables are different (so if you plan on being able to use your parking brake you need that).

The rear sway bar can be attached to a dx, but note that many of the dx chassis do not have the nut welded in the frame rail. You can still install a rear bar but it you may need to get creative or buy a bar with it's own mount system. One last thing, the CRX bar is 2mm bigger so if you can get one - go for the crx bar.
CRX si = 15mm
Civic si = 13mm

 

I just realized I didn't word my question very well, I don't own a hatch. What I meant was, will the bar off an si crx install pretty much directly onto my dx crx? (I have stock drum trailing arms)

 

Yes. You need:

- Rear Sway Bar (from either 88-91 civic/crx)
- Mounting Brackets
- endlinks
- Rear Control Arms that are threaded
- Hope, Pray, for a small miracle that your Chassis is threaded so you can attach the mounting brackets to the chassis. or else you have to do something like this guy.
