(Rough explanation). The EJ20H uses the same idea, but apparently not as smoothly, and I've heard of a lot of complaints of a dead spot from lag at the transition from 1 to 2 turbo operation. They call it the Valley of Death. It may be over-dramatized, but the EJ20H doesn't seem to make it into swapped Imprezas.

Thanks for the info! I was thinking it was a parallel setup? Learn something new right?
