I have a 91 DX hatch and a H23 motor. I want to put GSR brakes all around and I dont have a clue on what I need for the instull what year will work with my car and my motor.

 

You could take the brakes from an integra '90-'01. In the front, you need the knucckle, the disk, the caliper, the pads. That it. At the rear, you could take the rear disks brake assembly from a civic 'si '92-'95 hatchback, from an integra '90 to '01 (except type r) or a civic 'si '99-'00...You need all the trailing assembly. The e-brakes and the LCA if you wanna have the rear sway-bar, but that is not totally necessary for your brake upgrade...
