The third-generation Toyota 4Runner (1996–2002) is the platform LC Engineering has built its modern 4Runner identity around. It carries two engines: the 3RZ-FE 2.7-liter four-cylinder and the 5VZ-FE 3.4-liter V6. The 5VZ-FE is the marquee engine of the era — Toyota's first DOHC truck V6, the engine that anchored the 3rd gen 4Runner, the 1st gen Tacoma, and the 1st gen Tundra. LCE launched a replacement 5VZ long block in August 2025 that has become a center of gravity for the 5VZ rebuilder community.
Our 3rd gen 4Runner catalog is the deepest LCE 4Runner catalog by margin. For 5VZ-FE V6 builds we offer the replacement long block, full stroker programs, supercharger kits, turbo kits, header kits, performance camshafts, master rebuild kits, and the supporting components for high-output 5VZ builds. For 3RZ-FE 2.7L four-cylinder builds we offer long blocks, rebuild kits, and bolt-on performance. Suspension, drivetrain, brake, and OEM-replacement coverage rounds out the catalog.
If you are building a 3rd gen 4Runner, this is where LCE's engine-building DNA lives. Tech line: (928) 505-2501. Email: support@lcengineering.com.
