Integra Master Cylinder Differences
What are the differences between the master cylinders on an ABS and a non-abs Integra? I currently have an ABS master cylinder and brake booster running to a 40/40 prop valve on my track car. My brake booster took a dump so I'm looking to make some changes but i'm stumped on what mc to buy. There's nothing wrong with mine but a lot of people on forums say to never mix match. I found this diagram which says the ABS mc has a bigger rear outlet but i'm not sure what difference that makes. I'm installing the Wilwood 260-11179 adjustable prop valve so which booster and mc would be best?

I believe the only real differences are the orientation of the ears where they bolt to the brake booster, the actual size\bore, and the location of the the ports/outlets

Gotcha so if I just kept my MC with the larger rear outlet is that going to affect anything? I'll be able to adjust the rear brake bias so I wouldn't think it'll make a difference. Also on the MC which port is front and which is rear?

I don't why\what the difference is with the larger rear port, afaik I think the lines are the same size just a larger fitting, but im not 100% on that
someone else will chime in eventually

Re: Integra Master Cylinder Differences
The larger rear port does have a larger line coming from it. I have mine running to a factory reducer to get it to the port size of the proportioning valve. I am not running ABS so I don't know is the larger sized line runs the same size all the way to an OEM actuator or if it also goes through the reducer.
A quick look on any Acura parts catalog should show it if it's on a factory ABS-equipped car.

Re: Integra Master Cylinder Differences
The rear port is 12mm but the flare angle and tapper is the same I use a 12-10mm reducing thread insert cause the seal
is made on the flare no issues running a stock del sol booster clocked to point the bolts the opposite way and 92 integra abs master cylinder so ports line up the same all on driver side with front port point up a bit just back port has that reducer. 1” master swap
for any eg no welding or cutting line direct bolt on just need to make a spacer for the master cylinder as it doesn’t go in as deep. And run the booster shaft out as far as you can
