You can use Integra/Civic EX/Si fronts. If you want a big brake kit for the front, Summit has a Willwood kit for around $600. If you're going to Integra discs in the rear, it's really not necessary to go any larger back there. Just get some pads(AEM/Nissin work well for me) and slotted or drilled(or both) rotors if you want them, but those aren't really that necessary either. Make sure you get a 4-wheel disc proportioning valve as well. A 15/16" master cylinder and booster will also help pedal feel. If you have an extra $90 or so, you might as well get some stainless lines while you're at it, and they'll also firm up your pedal a bit.
