depends on how much boost you plan to run. anything over 10psi or ANY amount of boost with improper tuning will require buildup.
the H22's ring lands are thin to reduce hydrocarbons. this also makes them prone to cracking under boost. replace your pistons if you plan to exceed 10 psi of boost, or if you use a Drag kit (their fuel management is horrid). forged is the way to go, but you'll either need slipskirt pistons to prevent cylinder sleeve wear or replace the sleeves with iron. a lower compression piston will help in detonation control as turbocharging is effectively an increase in compression due to the increase in air ingestion.
rods. stock rods are fine for low boost. shot peen your stock rods to save money for medium boost levels, up to 12psi. replace the rods with H-beams if you're cheap, or I beams from Crower if you want a true high performance setup. a lighter rotating assembly reduces bearing stress and increases horsepower due to reduced drag, inertia, and friction.
get a quality head gasket.
have your whole rotating assembly balanced when the parts are installed, and use quality fasteners. a balanced rotating assembly produces more power and reduces chances of extra stress on the rotating components.
next time, do a search.
