* Engine Compatibility: The 96 Toyota engine and the 86 chassis are from different generations and have different mounting points, electrical systems, and transmissions.
* Engine Size and Power: A 96 Toyota engine is likely to be less powerful than the 86's factory engine.
* Modern Features: The 86 features modern electronics and a sophisticated engine management system that might not be compatible with an older engine.
Here's what you could do instead:
* Engine Swap: You could swap in a newer, more powerful engine from another Toyota model. This would be a challenging project requiring significant modifications and expertise.
* Engine Tune-up: You could focus on enhancing the performance of the 86's existing engine through modifications like a turbocharger, exhaust system upgrade, or a tune.
Important Considerations:
* Cost: Engine swaps are expensive, requiring specialized parts, labor, and possibly custom fabrication.
* Legality: Modifying your vehicle's engine can affect its roadworthiness and insurance coverage.
* Expertise: Engine swaps require significant mechanical knowledge and experience.
Before attempting any engine swap or major modification, it's highly recommended to consult with experienced mechanics and professionals to assess the feasibility and potential risks.
