Here's a breakdown of what's involved:
* Engine Mounts: You'll need new engine mounts designed to accommodate the crate engine's dimensions. These are not readily available; you'll likely need custom fabrication.
* Transmission: The 3.8L V6 likely uses a different transmission than what's compatible with the crate engine. You'll need a compatible transmission (and possibly a custom adapter plate) to connect the engine to the drivetrain. This could involve a significant transmission swap.
* Exhaust System: The exhaust system will need to be completely replaced or significantly modified to fit the new engine's exhaust manifolds or headers.
* Wiring Harness: The wiring harness for the 3.8L V6 is incompatible with a crate engine. You'll need a new wiring harness or significant rewiring. This is a complex task requiring electrical knowledge.
* Computer/ECU: You'll need a compatible engine control unit (ECU) for the crate engine. This often requires tuning and calibration to work correctly with your car.
* Cooling System: The cooling system may need modification to accommodate the larger engine.
* Driveshafts: Depending on the transmission choice, driveshafts may need to be replaced or modified.
* Body Modifications: In some cases, the engine bay might need minor modifications to fit the larger engine.
In short: It's a major project requiring substantial mechanical knowledge, fabrication skills, and potentially specialized tools. It's not a weekend project and will be very expensive. Consider the cost of parts, labor (if you don't do all the work yourself), and potential unforeseen complications before undertaking this swap. You might consider a simpler swap, like a different V6, if you're looking for a more manageable project.
