Most of those guys whose motor are still good are running somewhat low to moderated boost. So that not technically good on boost. This is how I see it(you might disagree). The rods on a H22 have a longer distance to travel. This might not take well once pressure is introduced. For example, you have 2 steel pipes. One is shorter that the other. One pipe will take more pressure once force is introduced. The shorter pipe will. Now you can get aftermarket rods and forged pistons to solve that problem, but the motor has to sleeved $$$.
I have seen dyno charts on both H22 and B series motor. They average the same power level with the same psi ,yet the H22 has a bigger displacement.
Now a fully built H22 is the way to go, but would cost way more that a fully built B series motor.

By no way I am knocking down H22 owners. Just discussing info
