Will a L28 engine 6 cylinder and 5 speed transmission out of a 1981 Datsun 280zx install into a 1994 Mazda b2000 pickup?

Yes, a L28 engine and 5-speed transmission from a 1981 Datsun 280ZX can be installed into a 1994 Mazda B2000 pickup, but it will require significant modifications. Custom engine mounts, transmission mounts, and potentially alterations to the drivetrain and wiring harness will be necessary. Additionally, considerations for cooling, exhaust routing, and compatibility with the Mazda's electronics should be taken into account. Overall, while feasible, it's a complex swap that requires careful planning and fabrication.
