it seems as though you need to do some more researching on what you have and what you want to do as far as hp goals.from your original post it doesn't seem like you know too much about what your options are or maybe even exactly what you have and the potentials good or bad.theres many diff routes to go.do a bunch of searchin and researching before dipping into a big project like this.i myself am a 2v fan.you want 600 wheel/ build yp the bottom end,ported heads,blower cams and a kb 2.2 or 2.6 at a good 18-20psi and your goal should be easily achieved.
