I am really looking into doing some serious work to my Focus as soon as my warrenty is gone. In my looking on the web, the only aftermarket crank I've been able to find was like 2,500 bucks!!! What can our stock crank take as far as hp? When I do all my block work I want to do everything right and I don't want to have problems with the crank down the road. Any help would be great!!
