Ok i was really sitting down today and thinking about the nitrous or turbo route and i basically came to the conclusion i'd rather go with nos just because it'd be alot cheaper .. now comes the question of what to buy? .. on my car it has aem intake and headers and exhaust .. im basically looking for more horse and dont want to ruin the engine (just paid 2700 for a rebuilt) .. is there any nitrous kits that wont completely kill my engine if i only use it maybe once or twice a week (basically friday/sats) .. if anyone has any suggestions thanks .. also maybe a place to buy it would be good also .. thanks

and also anything i need so i dont get busted by the cops! .. i heard it's all illegal .. thanks
