* Engine Compatibility is Complex: Engine swaps depend on a variety of factors, including engine mounting points, transmission compatibility, exhaust system, electrical wiring, and more.
* Missing Information: You mentioned "2600 on b2000 s gearbox" but I don't know what you mean by "2600." Is that an engine size? Do you mean the B2600 model?
* Year Variations: Engine options for the B2000 changed across its production years. You need to specify the exact model year and trim level.
Here's what I recommend:
1. Identify the Specific B2000: Determine the exact model year and trim level (B2000, B2600, etc.).
2. Check Mazda Resources: Consult Mazda's official website, service manuals, or online forums for detailed information on engine options for your specific B2000.
3. Consult an Expert: A qualified mechanic or auto shop can provide accurate information about engine compatibility for your B2000.
Remember, engine swaps can be complex and require expertise. It's crucial to seek professional advice to ensure a safe and successful project.
