Use a Toyota SC14 Supercharger off an Estima Van, remove the AC pump and get some brackets and piping made to suit. The SC14 Charger is a roots style supercharger with a clutched drive (just like the AC system) which you can tune the chipped ECU to turn on or off under certain load conditions.
Of course you will only get a low boost out of it 5-7psi, but it will boost the power out of the H22A enough to put a smile on your face. Best thing about the SC14 is you can run an intercooler after it bringing down charge air temps, ring lands are most likely your weakest link with the H22A..... but I'd say a good tune and the low boost would be OK.
Good luck with it all, I've been reading about this type of setup on a Euro R engined BB4 Prelude on another forum I frequent. It's nearing the final stages at the moment so will be able to post the results of that sometime soonish.
