Your saying a check valve is a honda thing? I know people with J's that have, or are running them. Also people with J's who havenot.

Its just a bunch of check valves, made so the MAP sensor doesn't see boost...
so pretty much bypasses the need to get a 2 bar map sensor? or depending on how much boost u plan on running?
so what exactly happens when the map sensor sees boost? i know it for vaccum, what what exactly happens? im just kinda wondering why hondas need it and jbodys dont?
As Shifted stated a check valve keeps the map sensor from seeing boost. I know he does not think a J needs one. I also know the first ever street turboed Ecotec needed one. When it saw boost it got a flashing CEL. Once the check valve (actually I think 2 of them) were put it it did not see boost, and did not get the CEL. My turbo car has a check valve as well (it came with it when I bought the car). This topic has been talked about many times on the ORG and many people run them and many peopl do not. I would say if you do not have one and are not having any issues with CEL's I would not worry about it.
