What do you mean strengthen the bottom end??
By fuel system do you mean just injectors and fuel rail??
Or up the boost on the current turbo depending on its efficiency and ability to perform at a higher boost level.
Forged rods and pistons and possible sleeves depending on power goals.
Higher volume fuel pump, larger injectors, and fuel pressure regulator. The stock fuel rail is capable of holding well over 500 whp, so it isn't necessary to upgrade.
