But then you have Integra LS's that slap on a B16 head and voala, VTEC! And B16 head has better flow, aside from valvetrain difference from the B18 ITR head.
For us Subarus, this would be not a 2.0L, but a 2.2L. The WRX heads are ported, so it's a higher flowing head and it's slapped onto a bigger than normal Subaru turbo engine; 2.2L. The 2.5L would be more like Honda's H22.
SO.... it's the infamous EJ22T('91 w/ oil cooler) w/ PORTED '03 WRX heads(shimless). The TGV's are also ported to release some more TOP-END power.
I'm not sure how much power capable this is...but I'd call this my medium setup opposed to my light setup (STOCK complete EJ22T engine w/ TD04L/TMIC/headerback boosting at 15psi w/ MBC). My light setup yield me 178whp and 244wtq and was quick enough to run w/ a stock EVO9 in my little wagon.
