Best bang for buck if you want to go fast in a straight line = FINAL GEARS. $1000 and you can pull 2-3+ car lengths on a stock S2 up to 4th!
1. Just because it's expensive and has a big brand name, doesn't mean it makes power. I knew a guy that had a spoon built B18C5...it only made 153 whp.
2. Nitrous is still the best bang for the buck in a straight line.
As for the guy who said "nitrous will rape your engine", go buy yourself a clue homey.
Tune the nitrous correctly, and it'll be fine...and fast. Proper timing, plugs, plug gap, maybe bump up the fuel slightly...I'd put at least a 75 shot on it.
