Yeah, if you don't want to loose all your low end...what little you have to start with. then definetly get at least an AEM
pulley and you said hard then also get a torque converter, I have seen some good ones for almost a grand. Oh, and that low end thing was just a joke. Or you could hook up nitrous so it comes on for the first 3 grand, that would help. I have a 5sp gt and even I noticed loss of low end when I got my header, although high end improved dramatically.
