However, it would be MUCH better if you stuck with the 22E heads for boost.
They have larger valves/valve openings than the 22T does.
You should swap cams & valve covers from the 22T heads over to the 22E heads & then you will have heads built for turbocharging.
Be warned. your compression ratio will not lower much, if at all.
The pistons & head gaskets to the 22T are what causes the massive compression drop in that particular engine.
Other than cams, valve covers, & valve size, the 22T heads are pretty much 22E heads.
My recommendation would be to put the 22E back together with the head parts from the 22T, run that for a while, & then save the 22T block for boost with the 25D heads (MUST be from 97-99 LGT/Outback as 96 heads have quench chambers that are too large for the 22T cylinders).
