I'm still rebuilding the motor. Got 98% of it done. I've seen the vacuum line diagram and all, I know where they all go. I just don't want them. Two of my friends who own 300z's just say to plug everything off. When I got the car the EGR was already ditched, along with more than half the vacuum lines. Instead of spending more money that I barley have, could I really just plug everything off? I just don't think the Supra will react as the 300z's. Thanks everyone...
