1st of all, im getting tired of people talking **** every time someone wants to modify there car. Second of all, then go buy an srt, but its like what 5ok, is it even out yet? 3rd, yeah probably about 30 hp, which would put you at around a hp to weight ratio of a 350 z. I dont care about the warranty and labor cost isn't an issue. I also plan on keeping this car forever. But that doesn't matter because i don't need to justify my question. If you have anything constructive to say then post it, but if you have so little things to do in your life that you must talk **** every time someone posts a question about increasing performance then shut the f*@k up. This forum is getting more and more annoying. Say it cost 3-4k. Thats alot, yes, but startech charges 5k for fugging cams that will give you 15hp tops. Use your head, no one here who has said "i'd get an srt instead" can afford one realistically, or else they would have got one. And just like everyone else who's been criticized, i wouldnt get the srt anyway because any man who considers himself a fan of sports cars would never buy an autofagic. Whatever, im convinced this is one of the least productive mechanical forums on the internet anyway. All the big talk everyone does, and no one has made a significant power upgrade yet. thanks anyways.
