Seriously though bro, if you are serious about becoming a threat to other "racers" (??) on the road, you need to swap your engine, or just buy a new car. I would recommend just a simple sr20de would be enough (IE- se-r engine). This would put you the next level up for performance/mods. The only way you would be putting a good investment into this current engine would be...yes..turbo. I have heard of several people running T25 turbos on the ga16, and they run low 13's and 12's. You should consider this if you are going to keep pouring money into your car, otherwise its pretty much a waste. I'm not saying this to be mean, just being realistic. I don't know if you are young. I'm 17 and I know that I will never be able to swap an engine, just because of money/ my parents would have a cow. Just offering some advice.
