EVO 3 is more light weight and new models are heavy, so when we compare power to weight Ratio EVO 3 can take down even a EVO6 (stock) also to do an EVO3 conversion it wont cost that much, so u have some money left in ya hands to do the modifications, anyway remember this well, this is like a rule, when it comes to EVO u have to take em to Nadeera or Ashan, no one else can make em fly
basic mods like Exhaust, Intake, more boost, 1 step colder plugs, and later u can change the internals ( pistons, rods, bearing, retainers, valve springs and valves, etc) and chanage the turbo, also u can get down an EMS and get a tune from Nadeera, u can make ur evo fly like a rocket,
im off to bed now bro, think and take a decision, gud night and bs
cheers
