im doing a rear disc setup on my 98 civic dx, which recently got an 2000 civic Si motor and type R trans. What i need to know is if the proportioning valve is the same for both model cars, 98 dxcoupe and 2000 civic Si.

Thanks guys, ive done little research but i think they are the same, can anyone back me up on this?

Cant wait to get back on track

 

They probably are the same...
Our '00 Si had the same size as our 97 H/B.
But I don't understand why you would want to change the one that is on the DX anyway?

look at it. It is either a 30/30 or a 40/40.

If not get the 40/40.

I found my 40/40 prop valve I needed for my eg off a 91 integra ls since they all had rear disc brakes. Lines are a perfect fit.

 

I put the 99-00 si brake setup in my ek hatch. my research turned up lots of opinions but the best info i found was that the coupe needed the 99-00si or 96-00 hatch proportioning valve as those two are 40/40 (same part number as well).
