I'm currently pushing 440whp and would like to continue on my jouney. As far as the engine goes, I was thinking about purchasing a short block from erl: http://www.erlperformance.com/mitsubishi-4b11 . Is that the only thing i'll need? I already have cams and springs. From my understanding it would be basically just swapping out the bottom ends and retuning? Im thinking about getting the BB2N (not sleeved).
