Since you have an 85 you really should plug the ARV on the turbo too. The BB in the line works there as well. You will see far more benefit from plugging the ARV than plugging the EGR. Also running your car with the EGR plugged and leaving the ARV functional is about the worst thing you can do for the environment.
