It is possible to install the engine from a 1990 Mazda 626 into an 1988 B2200 pickup, but it would require extensive modifications and custom fabrication. The 626 engine is larger and heavier than the original B2200 engine, so the engine mounts, transmission, driveshaft, and other components would all need to be modified to accommodate the new engine. Additionally, the 626 engine may require different fuel injection, electrical, and exhaust systems, so those would also need to be addressed.
Overall, while it is technically possible to install the 626 engine in the B2200, it would be a complex and challenging project that would require significant fabrication and modifications.
