Also also, "WRX motor" would be shortblock and heads I would think. Manifolds, fueling, and wiring shouldn't be swapped if they don't have to be. So the injectors wouldn't actually be a tuning issue, if the STi manifold and fueling physically bolts to the EJ255, which I'm pretty sure will (just not vice-versa).
