A classic 1988 Mitsubishi Starion has been given a new lease on life with a powerhouse engine swap and custom touches. Instead of the original turbo setup, this Starion now houses a BMW M57D30 diesel engine-a 3.0-liter inline-six known for its durability and tuning potential. The transformation took roughly a year and a half, turning the 1980s sports car into a unique beast that bridges retro flair with modern muscle.
The Starion’s original 2.0-liter turbocharged engine produced around 150 horsepower, fitting for its time but modest by today’s standards. Swapping in the BMW diesel straight-six changes the game, providing a different torque curve and a reliability edge often missing in classic Japanese sports cars. This engine is famed in tuning circles and popular among enthusiasts seeking robust powertrains in lightweight chassis.
What makes this build particularly interesting is the choice of engine lineage. While many tuners favor the legendary Toyota 1JZ or the 3.0-liter 2JZ inline-six and variants like the 2.5-liter 1JZ, this project takes the less common BMW route. The M57D30 offers a blend of strength and efficiency, historically powering vehicles with smooth performance and respectable power delivery.
Projects like this highlight a growing trend among classic car enthusiasts: combining vintage aesthetics with modern engines from diverse brands, often crossing national boundaries. The result isn’t just a nostalgic throwback but a versatile vehicle ready for spirited drives without sacrificing reliability. The Starion’s boxy, aggressive 1980s look retains its charm, while the under-hood overhaul ensures it is more than a museum piece.
