IN THEORY, if I built a EJ255 motor with forged rods/pistons/Manley crank, King bearings etc. (doesn't have to be those parts exactly, just an example) and kept heads, compression, boost, turbo, injectors, intake, exhaust and tune STOCK....what would that do to the life of the motor if anything? This is purely a technical question, not looking for financial advice as I have no plans whatsoever to mod my motor for a long time (its the last thing I intend to mod). I would assume the forged pistons would help with the common ring land failures of the EJ series but what about the spun rod bearing issues? Are there any downsides to having forged internals without tuning the engine for an increase in HP/Tq (other than looser tolerances when engine is cold)?
