this is a poormans type r. the b16 head flows 8% better from the flow chart i saw (stock). but u are lowering the compression opposed to the gsr head

basically whats involved is u take a gsr head off, get new gsr headbolts or studs (i dont reccomend reusing headbolts) put the b16 head on with a new gsr head gasket. stuff some ctr or itr cams in it, get an itr tranny, and u have a poormans hype r.

its alot more reliable than a thrown together ls/vtec, but a proprer ls/vtec ehhh id still reccomend a poormans. powerwise with the ctr cams, itr tranny, i read a guy was running low 13s all motor in a vx hatch. but im not sure what an ls/vtec would do with the same mods (and properly built).

go with the poormans type r.
