Couldn't find a definitive answer so thought I'd ask here.

What years and models could I use as a doner car for the prop valve and brake lines to delete ABS off my '99 Integra?

 

'98 - '01 non-abs Integra.

 

Aren't there some other cars that work also?

mines a 95 but i used a 4040 valve off a rs and a and f pipe off the rs, and made custom ss lines for the MC so i didn't need the other hard lines

 

No, not in a 100% plug and play sense anyway.

 

99-00 civic si
96-99 civic 2dr dx and lx
96-99 civic hatch cx and dx
These models also use the same 4040 pv as a 98-01 integra rs

 

No they definitely don't

'96 - '00 Civic CX/DX(except Sedan DX)/HX/Si all use the same prop valve, but it's not the same as the '98 - '01 Integra prop valve. Looks the same but the bias is different.

 

Pretty sure all the the models I listed share the same number as the 98 + integra. When I was searching for one I ran numbers and came up with those. I ended up finding a 99 si in the junkyard and got the pv off it. Way I see it a 4040 is a 4040 especially on civic and integra chassis where almost everything is interchangable for the most part

 

They're just not the same. Check the part numbers, there's a list floating around here somewhere that I made a while back with all the part numbers. Integras had larger front brakes than the EX/Si models and used a larger MC this is why the prop valve on the Integra is different Your own list is a mess anyhow, you've got years that cross 2 generations of civics.

 

well if there is a difference, its not much to notice a difference in feel. I dont see how there could be and still be a 4040 valve. and yes i messed up a year its fixed now.

 

i would **** with the 4040s from a civic that has drum brakes, i could image there biasing will be different. just get the 94 rs prop valve or the 99 rs prop since you have a 99 integra

 

The thing that matters is the part number, if the part number is the same it's the same part. '94 and '99 RS prop valve are completely different in terms of how the lines connect and the valve itself bolts to the firewall.
