Experience aggressive trail torque and rugged mountain pulling power with this high-performance Toyota 4Runner 22R-EC Remanufactured Engine. Each 2.4L 4-Cylinder 8-Valve SOHC long block features performance-profile camshaft timing and CNC line-honed main saddles. Technicians must retain the rear main seal housing and fuel pump eccentric from the core engine and complete an exact 500-mile break-in oil change.

Built with heavy-duty cast iron block casting 22R, this high-performance assembly features laser-straight cylinder bores align-honed for crankshaft journal roundness. The rotating group features a micro-polished forged steel crankshaft, balanced forged steel connecting rods, and oversized hypereutectic pistons with coated skirts. SOHC 8-Valve cylinder heads receive high-flow valve seat profiling and diamond deck resurfacing. Net weight measures 240 lbs within crated dimensions of 36in length by 36in width by 36in height. Sump capacity equals 4.5 quarts.

Key Features of Toyota 22R-EC

4-wheel-drive enthusiasts buy Toyota 22R-EC remanufactured engine long blocks to restore rock-crawling reliability and gain expanded mid-range torque. This high-performance long block replacement provides verified machine shop tolerances for vintage Toyota off-road trucks and sport utility vehicles.

- High-performance camshaft grind provides enhanced valve lift and duration for expanded torque bands.
- Heavy-duty dual-row timing chain conversion prevents single-row plastic guide breakage under load.
- Block casting 22R features precision align-honed main bearing tunnels for crankshaft stability.
- Diamond plateau honed cylinder walls establish an Ra 16 micro-inch finish for rapid ring seating.
- Micro-polished crankshaft journals eliminate runout to protect tri-metal bearings from hydrodynamic breakdown.
- Multi-layer composite cylinder head gaskets ensure combustion chamber seal integrity under elevated thermal stress.
- High-tensile cylinder head bolts supply uniform clamp load across all 4 combustion chambers.

Dyno Load Precision Machining Tolerances

Dyno cell testing validates mechanical oil pressure and high-output torque delivery before crate packaging. This upgraded 2.4L 2366cc SOHC engine outputs 125 HP at 5,000 RPM and 150 ft-lbs of shaft torque at 3,200 RPM. Crankshaft main journal oil clearance holds between 0.0011in and 0.0015in, while connecting rod clearance measures 0.0012in. Individual cylinder compression gauges verify 180 PSI across all 4 cylinders. Hot engine oil pressure maintains 55 PSI at 3,000 RPM with regulated coolant operating temperatures steady at 190°F.

Vehicle Fitment Drivetrain Guide

This engine fits 1984 to 1995 Toyota Pickup, 1984 to 1995 Toyota 4Runner, and 1984 to 1985 Toyota Celica models equipped with the 2.4L 2366cc 22R or 22R-EC engine. Compatible drivetrains include rear-wheel drive and 4-wheel drive paired with 5-Speed manual or 4-Speed automatic transmissions. This unit does not fit earlier pre-1984 tall-deck 22R blocks, 20R platforms, or turbocharged 22R-TE engines due to block deck height and combustion chamber volume mismatch.

Installation Protocol Service Requirements

Technicians must transfer the rear main seal bolt-on housing from the core engine, install the mechanical fuel pump eccentric on carbureted setups, and prime internal oil galleries. Operational warnings restrict deployment in custom turbo projects exceeding 5 PSI boost or extreme rock bouncers lacking secondary oil filtration.

- Pre-fill the oil filter and prime lubrication passages with high-zinc 10W-30 conventional motor oil.
- Drain initial break-in oil and install a replacement oil filter at the 500-mile service point.
- Recheck mechanical valve lash clearances on intake and exhaust rockers at 1,500 miles.
