Depends what your doing to it... will decide how much power... usually with a good set up without opening the engine at all... could see around 200wkw 'ish mark.
Stock? I'd perfer a B18C for street. Larger displacement, more compression. As for power, too many factors, 110kw-200kw+ at the wheels. The string is long, depends on complete setup - turbo kit, tunner, money etc.
