Building my 2L ej205. I will be shooting for 550-600whp. Anyone have suggestions on what type of rods and Pistons I should go with?
Build a 2.5L for that power.
2.5L heads are a bear to wire up, and you really have to sacrifice AVCS (which is the main advantage anyway).
PnP'd 2L heads chamber-matched to the 2.5L block is my suggestion, and clearly you agree.
