my b20/vtec put down 172hp and 138tq with intake header exhaust. i used a jdm b20b, a 1st gen b16 head a itr intake manifold, gsr TB (58mm). a tiny iceman intake and even smaller sohc thermal exhaust and a dc 4-2-1 gsr header. prolly could have put down more with a bigger everything

you might make a few more hp with the gsr head cause the combustion chambers are smaller
