I'm sure this has been addressed in the past, but Google is failing me somewhat on the searches right now.

Planning on running a Wilwood setup front and rear, nothing too fancy just the 4 pot in the front and single piston in the back. Stainless lines.

Ordering a prop valve relocation kit right now and wondering if upgrading to an ITR master cylinder would be worthwhile? If using the ITR master, would I need an Integra brake booster?

Sorry if any of these are silly questions, long couple of weeks and critical thinking is hard.

Only if you have ITR brakes

My engine bay is empty right now, so if there's any easy opportunity to change it, now would be the time. That being said I think if I got the 98-01 GSR/ITR master cylinder, I think I'd need the brake booster too. Gets expensive quick lol.

I'm trying to figure out right now what size bore I have on the stock MC, the part number for brake master on 93 Si is 46100-SR3-043, I'm trying to confirm if it's the 15/16" bore, in which case "upgrading" to the ITR 1" would be fairly pointless.

/thread, sorry this was a bit of a pointless question I could have solved by myself. Like I said, been a long couple weeks... Need a vacation :/

It has a good feel to the brake pedal but you'll have to learn proper braking again as you might end up locking your brakes thus sliding into things you didn't want to slide into. I know...

I thought all the later Integra's came with the same 1" Master Cylinder and thicker (than Civic) Brake Booster. The early DC Integra's came with either a 15/16" or 1" depending on if it was Non-ABS or ABS. I don't know much about the JDM ITR.

n the 97 to 98 transition Acura/Honda did change the style of the Master Cylinder (angled vs horizontal mounting bolts at the brake booster).
