On EF's and EG's you could put in integra prop valves which had on them the number stamps
this is from my post above
Showing you the part number crossing
2000 si has 46210-S04-902
then a civic, 2 door, dx model 1996 - 2000 46210S04902
These are numbers from honda ..
Clearly shows...
both blinx9900 and myself are saying is that you don't need one.
If you do your research a north american 2000 si with rear disc has the same prop valve as 96-2000 ek's with drum brakes.
Made no sense to me because everyone was saying you need the 2000si valve.
But if you cross the numbers...
Hey Blinx you are one of only a few people that have come forward and said this.
I have been fighting a huge following that said the 99-2000 civic si USA non abs prop valve was special because of rear disc...
But doing my own home work.. have been only able to confirm what you have just said...
