can be done.its matter of worth it anot. i will cost u a bomb. moreover 200Whp region seem to the barrier limit. some bot supercharge 5AT altezza kaki also running around that power only. ive spend 6-8 k on my altezza. power increase still not noticable. hahaha . total investment on major parts for my k20a around 12-15k.stock piston and crank. 240whp 22.9kgm torque. and theres more power to be extract if i still want to continue. but its enough. moral of the story, pick wisely on what to start with. want crazy power but die die still want N/A. Go for Honda. want balance + comfort handling go for altezza. want cheap raw power, go for turbo.
