umm..dont boost h22 without building it...

i think the walls are FRM...
i love h22s...if i had unlimited funds, i would send my motor to bisimoto for their c2 package...

sleeve block, bore& stroke..forged block internals, build the head ...
turbo that bitch
i think you should hit 1000 hp no problem...bisimoto guarantees it..and i doubt they even bore and stroke...

h22s are awesome..only 50 lbs heavier than b series..im sure..
