Nitrous, Super Chargers, & Turbos - rev hard

some day when i get enough $, i would like to buy a rev hard stage 2 kit. it seems like a good kit. And it seems to have almost everything i need, right?

Yeah its got everything you need, but does your engine have everything you need? Probly not. If you are running stock internals, then you could still install the Stage 2 kit, but you would only be able to run minimal boost. For the stage 2 kit to really get your car moving your gona need to buy forged pistons, rods, etc. to beef up your internals, otherwise you'll destroy your engine if you try to run too much boost.
