Among engine builders, the LQ4 engine is valued as a strong foundation for modification. Its cast-iron block can handle significant increases in power, making it suitable for turbocharged or supercharged builds. With upgraded camshafts, improved intake systems, and proper tuning, the engine can exceed factory power levels without compromising reliability. This adaptability has made it a favorite for engine swaps and custom projects, especially where durability is required alongside performance. The LQ4 engine proves that strength and tunability can coexist effectively.
