I had the same question ounce. here's how they answered me. If you don't already have the h22 doing the swap will equal the total HP if you were to turbo the f22. about 200-220, somewhere in that neighborhood.

doing the h22 swap costs more money then to turbo the f22

unless you have loads of money swapping to the h22 will be most valuable, since you have a larger aftermarket supply to build it, you'll have endless fun

I for the other hand have null to slim amounts of money, so a cheap CAI is as close to any kind of induction as I can get. hehehe
