i have a 98 volvo s70 turbo, the turbo motor blew an I install another motor of the same model but non turbo in the car and install original turbo kit on non turbo motor. Now car starts up fine but allot of white smoke, what could be the problem here?

Since oil burns black, "white smoke" coming from an engine is most often steam. You could have water leaking into either the combustion or exhaust systems.
