The F22 is more boost friendly from what i've heard. They are a reliable and strong motor. I've had several people say that there is a guy on some honda forum out there running his almost stock F22B at 14psi and getting 300ish horsepower AND it's his daily driver plus hes quite a few miles on it, and no problems. If I were you I would build up your own turbo setup for your F22 and have it tuned.
