i have to pass emmisions and not sure what is needed and what is not.
1) in prior searches i have found that the egr valve does nothing for emmisions. is this true
2) is the vapor canister needed
3) my plan is to run cats. with the smog pump blowing into all the time and cap off the heads. is this correct with the factory five cats
4) i have a supercharger that is 50 state approved for emmisions. i would like to put 30lb injectors in the car. will the bigger injectors after the emmision test

1) Not true. EGR system reduces NOX and other unburned gases.
2)It doesn't hurt to have the vapor canister.
If you don't use it you will smell gas in your garage when you car sits on hot days.
3)Recommend if your going to use the Catalytic coverters run it like the factory does.
4)30lb injectors shouldn't be a problem as long a you have a MAF that is calibrated for 30lb injectors and make sure that the MAF is emission approved.

jammin, I would recomend talking to an informed adminstrator or tech person at your emissions program. that way you wont spend a lot of time,effort or money on something you dont need or wont be enough when you go to test. chris
