While it is possible to put a 2WD motor on a 4WD chassis Nissan Truck from 1995, it is not advisable to do so. Doing so would require significant modifications to the vehicle's driveline, suspension, and other components, which could be costly and time-consuming. Additionally, the performance and handling characteristics of the 4WD chassis may not be optimal with a 2WD motor.
Therefore, it is generally recommended to keep the original 4WD motor and drivetrain in place to maintain the intended performance and capabilities of the vehicle. If you are considering swapping the motor, it is advisable to consult with a professional mechanic or technician to assess the feasibility and potential implications of such a conversion.
