Cams can't be justified for most people. It gets costly replacing 4 of them. Heads, I wouldn't do that either. The stock heads are about as good as your going to get. I would focus on the suspension. If you're drag racing, then LCAs, adjustable shocks, poly bushings, etc. You might also want to consider getting some decent rubber out back. I know you're not hooking, lol! Losing some rotating mass as previously posted is a good idea too. Wheels, DS, all that stuff. Just depends on how much you want to spend and what your goals are.

 

thanks for all the feedback... im not into drag racing. besides going to the track here n there for kicks i drive it on sunny days basically. ive just always had somewhere else to go with the car.. exhaust intake tune gears etc.. now that its all done im trying to figure out where to blow money next lol. i have 315's outback already so that i dont need. i dont really want to set up the suspension to drag race because i dont do it enough. i guess i want more power!! procharger has been in works for a long time.. not sure if im ready to spend that kinda cash in one shot.. was just wanting other simple mods to help increase power but im starting to run out of ideas. the flywheel clutch driveshaft seems like a solid idea!

 

1)flywheel= lightweight
2)Alu DS
3)tubular K member = 30lbs saved
4)aluminum intake spacer
5) 4.10's
6)tune
you'll drop 50lbs and pick up ~15-20 HP or more, and with the lower reciprocating mass MPG won't suffer from the 4.10s

 

I would do the suspension, i use MM but there are others that are good to.
