* Engine Size and Compatibility: The Supra engine is significantly larger and heavier than the Celica's. It would require major modifications to the engine bay, including cutting, welding, and potentially modifying the chassis.
* Transmissions and Drivetrain: The Supra's transmission and drivetrain are also different from the Celica's. You'd need to find a compatible transmission and adapt it to the Celica's existing drivetrain, which is a major undertaking.
* Electronics and Wiring: The Supra's engine management system and wiring harness are different from the Celica's. You'd need to rewire and reprogram the entire system to make the engine work.
* Cost and Complexity: The sheer amount of work involved would be incredibly expensive and time-consuming. You'd likely need to find specialized mechanics and parts, which would drive up the costs.
Alternatives:
Instead of attempting this swap, consider these options:
* Engine Upgrades for the Celica: You can significantly improve the performance of the Celica's existing engine with upgrades like a performance exhaust, intake, and ECU tune.
* Turbocharging: Consider adding a turbocharger to the Celica's engine for a boost in horsepower and torque. This is a more feasible option than a full engine swap.
Conclusion:
While it's technically possible, fitting a Supra engine into a 1995 Celica GT is not recommended due to the immense complexity, expense, and potential for complications. The effort involved is not worth the potential gains.
