46100-SH4-A11
Holly $h!t, it's already discontinued from Honda. :\

Here are the options from Oreilly. They have a reman unit for the same price as a new Centric unit.

Their parts database on www.centricparts.com is the $h!t. I haven't found one single flaw in it yet.

If using the 15/16" keeps you from having to re-bend/flare lines, I would go for it. You will be hard pressed to tell the difference from the 1".

The 15/16 is used on NON-ABS Integras (RS) and the 1" is used on ABS (GSR/LS). Both cars use the exact same calipers so no worries about spongy pedal etc...

The main difference is that the 1" will give you slightly less travel, yet the bigger booster makes it just as easy (or easier) to press. Personally I believe Honda uses the bigger MC & BB w/ ABS because it will be easier for the driver to lock up the wheels & fire the ABS system. My theory is that 15/16 might offer better modulation for non-abs applications.

Now the reason we recommend the 90-91 Civic EX 15/16" MC specifically is cause it bolts directly to your existing booster & hard lines. Very little work. And since your combining it with your "small" stock booster, you can expect the pedal to be very stiff with even better feedback & modulation than before. Both are desirable traits for a non-ABS sports car.
