i have a dx coupe and im getting ready to do an si rear disc conversion, ive already grabbed the entire trailing arms with lca's and compensator arms with all bushings and of course the disc assembly plus e brake cables. i also have an integra master cylinder and brake booster. ive been getting mixed answers from the internet about which prop valve to use and i looked up the part numbers on acura oem and the dc integras non abs vs. abs proportioning valve seem entirely different... could i use one from a DA integra?

 

96-00? 92-95? need this info or we cant help you much

 

as long as it's 4040, you should be fine.

 

i got the 4040 to go with mine but i have yet to install it all.

 

thats true^, but if he has a 96-00 dx he doesnt need to change the prop valve, they are the same as 99-00 si.

 

Use a prop valve from the same type of car you got the discs from. If your car is abs, use one from an ex.

 

sorry i forgot to clarify that i have a 95 without abs http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWNX%3AIT i ended up buying this

 

If you have a '92 - '95 with small front brakes and want to use rear discs use a '92 - '93 Si prop valve (stamped 3040)

 

****... what will happen if i use the 4040 for a while till i get the fronts upgraded too

 

Wow, you got raped on that prop valve.

 

yea i was goin to ask same ? on 4040 i have a stock eg si what adv will i get with a 4040 my 3040 is leaking

btw my eg si is non abs

 

I would presume different sized orifices are the only difference between all these different prop valves. If the 3040 came on the car, keep it.

 

get another 3040, it is designed for small front disk with rear disk.

 

well i have a leak in my 3040 and got a 4040 off a buddys wrecked car

 

it will work, however if this were me i start looking for a 3040 for a long term fix.

 

ok i had been but kinda hard to come by with out buy from honda for 2bills

 

ehh, try hondapartsunlimited.com, they have the best prices on oem stuff that i have seen so far.

 

yea i forgot about them i look on there from time to time

 

i bought one like that but not that specific one... im just ganna buy some complete ex knuckles, hopefully today from a local if when i see em theyre not in bad shape.. then i can use this prop valve? http://cgi.ebay.com/ebaymotors/ws/eB...=STRK:MEWNX:IT

 

The 3040 comes on a bunch of other 92-95 Civics, not just the Si .... easy to find if you know what you're looking for.

 

Interesting that you just listed the 92-93 ... did 94-95 (non-ABS) have a different one?

 

Hmm, after doing some research it would seem that you are in fact correct.

Again, after some research it turns out they are the same, weird when you consider that the front brakes on the '94 - '95 models were larger EX style brakes.

Below is a list of what i've found, i've bolded the 3040 prop valves, the others in the list are all 3030.

46210-SR3-962 VALVE ASSY., DUAL PROPORTIONING 1995 CIVIC Si
46210-SR3-962 VALVE ASSY., DUAL PROPORTIONING 1992 CIVIC Si
46210-SR3-962 VALVE ASSY., DUAL PROPORTIONING 1992 CIVIC DX (sedan)
46210-SR3-962 VALVE ASSY., DUAL PROPORTIONING 1994 CIVIC LX
46210-SR3-013 VALVE ASSY., DUAL PROPORTIONING 1992 CIVIC CX
46210-SR3-013 VALVE ASSY., DUAL PROPORTIONING 1994 CIVIC DX (hatchback)
46210-SR3-013 VALVE ASSY., DUAL PROPORTIONING 1994 CIVIC VX
46210-SR3-013 VALVE ASSY., DUAL PROPORTIONING 1994 CIVIC DX (coupe)
46210-SR3-013 VALVE ASSY., DUAL PROPORTIONING 1994 CIVIC EX (coupe)

 

ok well then if i just upgrade to gsr fronts the 40/40 would be the correct prop valve right cause i am in process of doin all my tech research on what diff honda/acura brake parts performance is in diff combo's since i work at in a race shop i can test diff parts

looks like so far a 1" master/booster, Gsr fronts, Ls rear is best setup for a DD using stock parts but have a couple other parts to test psi they can put out

 

thanks for the list man im sure it will help some people out... curious about the 1994 ex having a 3030 since it has the larger brakes

 

so i bought a pair of ex knuckles and i just ordered some replacement rotors cuz the ones it came with are looking kinda rusted.. heres my final parts list.. please tell me if everything will work out alright with this setup paid a total of $280.. too much?

si rear trailing arms with si ebrake cables,
ex knuckles,
integra 4040 prop valve,
integra brake master cylinder and brake booster
