I know I'm going to get some slack for not looking this up in the Faqs, but I'm already confused enough as is. This is my first honda project and I'm very new to cars and learning as I go.
I just bought a 91 ef that already had the conversion. I desperately need new brakes, but I'm unsure what year to buy the integra rotors, calipers and brakes. I don't know if it matters but i'm assuming 90-93.
I'm not sure what is on the car, trailing arms or any of that. i just know on the sheet i received from the previous owner it states "rear integra disc brakes".

 

I am on the same boat as you my friend, I dug around a bit, compared parts numbers and interchange part numbers, and what I came up with is this:

As long as they ARE from DA integra these should be fine.

Now, get on Acura parts website, get the parts numbers for both calipers, and google away!

So the car you have came with a partial swap? just the trailing arms and nothing else there?

 

safest way, just take off your pads and take them to the autoparts store. ask for DA and DC and see which one matches

 

Look at the trailing arms and look for a number like pr3 pr4 etcetc.

 

Since you're not sure of what you have at all, it would probably be a good idea to get under there with a flashlight and get part #'s off the trailing arm, brake caliper, rotor, pads, anything. That way you KNOW what you have. You never know when you'll need wheel bearings, bushings, end links, etc.

 

Thanks for the tips. It just snowed here, so now I get the pleasure of freezing and looking at part numbers! haha.
I'm not totally sure of anything on this vehicle at this point. It's a mismatch of everything. I wish people would keep a more accurate detail of the parts they swap on their cars not only for themselves, but even more so if they think in the future they might sell it.
