the 4ag is used alot in offroader racing. cheap! get a 100kw or a 4agze supercharged with box/driveshafts,harness and computer. for what you want a frontcut would be the way to go as you will get driveshafts and radiator etc etc.your looking around the $1200 mark for a 100kw or $2200 or so for gze frontcut.
