Okay lets see here. I have a 97' Civic DX. Currently there is front and rear brakes from a 91' Integra. The rear brakes do not engage. I have the proportioning valve from the same year teg. I feel the 40/40 will fix it, but at the same time I DO NOT want to re-route all my line. I am curious if any of you on here can help me find out if the SI/EX proportioning valve from an EK will work even though my brakes are NON ABS. It would make it so I don't have to re-route any of my brakes lines & the same guy I got the teg from is willing to exchange. Please let me know of any helpful information. Thanks.

If it's a coupe or hatch it's already got the same prop valve as a '99 - '00 Si (DX sedans are different though)

If the rear brakes aren't working either the brakes aren't bleed or the calipers are seized. Even with the wrong prop valve the rear brakes will work, they'll just lock up before the fronts.

nice, this is some definite reassurance man, thanks!

He's right. The prop valve only makes a difference when you start getting into the higher and higher pedal pressures. As more weight transfers off the rear tires from braking hard, the prop valves job is to limit the rear line pressure compared to the front. This keeps the rears from locking which causes oversteer.

BTW: The worng prop valve may caues too much rear bias, or may cause too little. You wouldn't know for sure without testing. I suggest you compare the part number of the prop valve from your year/trim-level with that of the 99-00 Si. If the number is the same, then your good to go...
