just to add... forced induction is the best bang for your buck but itll cost you up front... something to be said about waving bye bye to the brand new BMW M3s. If you dont have alot of money readily avaiable but want power go for a procharger or vortech if you dont mind putting in 8-10K go for a whipple or Kenne Bell and have more power sooner.

 

another good Supercharger is the Kenne Bell 2.6L

 

very good blower just think its over kill unless ur wanting 600 to wheels down the line
