Disc Brake Swap from 97 LS to 96 EK coupe, few questions.

[TheProfiteer]

Ok I know that if do a suspension and brake conversion on my 96 EK coupe from my Integra I have to change this one part, I do not know what its called but it looks like a brake fluid hub, its right there on the firewall left and down from the master cylinder.

Here is the situation, the civic "hub" has 5 brake line connection while the integra has only 4 and they are also shaped diffrently.

If I want to properly utilize the four wheel disc brake swap I know I need to change that one part.

But since these two hubs are not compatible, where do I get the right one?

I am thinking I need the fluid 'hub' from a 99-00 Si, but I am not sure.

does the Si have four wheel disc brakes? And is that hubed shaped the same as it would be on a 96 ex coupe?

Ok so I found out that that thing is called "proportioning valve"

so which one do I need to get to make my disc brake conversion operate at optimal capacity?
