Alright I have a 2000 Chevy Tracker with the 2.0L with a 5 speed manual and 4x4. The motor is shot and I have a 2.5L out of a 1987 Jeep that I am thinking about putting in. Will the 2.5 jeep motor bolt up to the tracker transmission? Will I need a adapter? Would it be easier to swap the whole drivetrain (motor, transmission, transfer case)? Please help me out here.
