A 1981 720 ute is a Datsun L18 engine. It will not be legal to fit such an engine into a 1989 vehicle as it won't meet pollution requirements (the reverse is allowed). Although I know nothing about Navara utes, the L series engine was discontinued before 1989. Z and L seies engines do not interchage with each other's gear boxes, though a full transplant my be possible.
