well i am working on getting my 3sgte up and running in my car and i was reading through the manual and it keeps referring to the egr valve and the vsv and im just a little confused i know the jdm dont usually have one so why does the manual keep referring to it? as well is the vsv needed if you dont have an egr?

thanks matt

doesn't the MR2 3sgte come with a EGR system?

yes the alltrac and mr2 both have vsv and egr
