OK, check out my current mods below, and take into account I'm planning on supercharging in the next 1-2 yrs. What should I do now (clutch, injectors/fuel pump, intake, new exhaust system, etc???

if you have stock inj. and fuel pump i would go ahead and replace those.....
Not sure about your exhaust....you have shorties and ??? is the rest stock? then definitely upgrade there...your biggest bottle neck is the stock heads..which are done so the exhaust is next...Then go w/ the intake....

Bottle boy is right

Get some 30lb injectors cause your gonna be blowing soon, and a 190lph fuel pump, you'll also need an adjustable fuel pressure regulator. If you still have the stock H and cat back, get a new exh., get a high flow cat H pipe and a new cat back. Then do intake.

Thanks guys. What exhaust system (manufacturer/size/catsor no cats etc?) would you recommend? How about the intake?

MAC w/ a cat? Wouldn't it be better to go w/ out the cats? GT40 or Twisted Wedge?
