In the interest of easy (that would be no internal engine surgery). Installation of 1.9 rocker arms would raise the valve lift (.258 cam x 1.6 =.413in/ex factory to .258 x 1.9=.490in/ex) by only removing the valve covers. Also with that move, you could drop several supercharger pulley sizes to spin the supercharger faster and in-turn create more boost. Probably going to want to change your spark plugs to a hotter temp range (for some reason they call that a "colder plug") as the plug electrode slowly melts away and you have to re-gap your plugs all the time to stay in tune.
