A lightly boosted V6 will run circles around a lightly boosted I-4, so the I-4 will need more radical components to handle higher boost just to keep up with the V6. That means for the same level of performance you will shell out more money for the I-4, and have less headroom to tune it because it will already be pushed closer to the limit just to feel like a mildly boosted V6.
Why is it that everyone who claims how a boosted I-4 is so awesome acts like an I-4 is the only engine that gets better with boost?
