So we've all heard a lot of heresay about this amazing swap k24 block to k20(Z3) head. whats the truth about this swap? A TSX block will work and so will the crv block? ive heard.... how difficult, how much, is it a direct bolt in...no, but what about the wiring? what parts are better left in the k20 head, I hear the TSX cams are more aggressive??....i also hear that the oil pump will need to be modified to make it work??? when searching for a doner block what year is best??? can someone please enlighten us, lift the vale of assumption and get some clear answers, cause the way I see it, 2.4 with high compression pistons is a much safer way to put down power then turbo or super, last longer too.
