How much money have you got?If you have enought just go with the Brand names their all about the same price anyway. Dont get lured into extra expensive stuff ...those last 1 or 2 HP increase is gona cost you triple the price and not worth it if you dont increase your hole package like racing pistons&engine components, new manifold new injectors and new intake manifold and induction kit....if your not doing it yourself as part of the kick then dont do it at all...buy a beefier car
