Top 5 mods to add HP

[rick3000]

If you are concerned with HP and straight line acceleration you bought the wrong car.
These cars accelerate plenty fast, and handle better than most other high HP cars. The only cheap HP increase is to desnorkle, it is a proven 2+ HP.

linkjones,
If you are having overheat problems and your car is dumping coolant you have cooling system problems... Bad t-stat, clogged radiators, bad coolant cap etc. Others have replaced their motors with a 3.4 996 without cooling problems or fuel starvation. Have someone who really knows these cars go over your cooling system.
