Standard bzr levin is about 145-155 hp, pendin on its condition though it would be more if it was just out from japan, there around 155 - 160 hp from japan but over time it decreases..
as for mods, stay away from turbo and nos, nos why bother?.. and turbo a waste of time on a ae111 levin, plus if ya wanted too turbo it just get a bzg levin there supercharged and it works alot better with thaose engines.. I'd be thinkin along the lines of an exhaust system, slotted rotors, uprated rated brakes, tyres (toyo r888's) cusco struts, trd spark plug leads, just litttle bits and peaces, i;ve tuned a levin before and thats what i done but i suggest gettin urself on a forum and get urself familar with it and all that..
