If I am looking to do a daily driver with around 500hp for cheap, whats the best way to go? It sounds like it is possible to do it NA which I would prefer because I don't want to add to much weight upfron since I will be autocrossin this car. But I don't want to do anythin extreme either. Maybe a low boost turbo? I spose I would need to lower the compression ratio even with a low boost turbo. A supercharger would work I guess but again weight and looks are important and I don't want the supercharger to detract from the engine... Anyone have any ideas on the way to go?
