Nissan Hardbody Pickup D21 KA24E 2.4L L4 Engine 1992-1996

Description

Eliminate blown head gaskets and distributor timing drift across work trucks with this Nissan D21 Hardbody KA24E Remanufactured Engine. Each 2.4L 4-Cylinder 12-Valve SOHC power plant features casting 72P wide-port cylinder head architecture and an 80mm distributor mount pattern. Technicians must prime internal oil galleries before startup and execute an exact 500-mile break-in oil change to protect rocker pads.

Constructed around a cast iron block marked KA24, T50, or F45, this assembly provides long-term cylinder bore stability. The rotating foundation features a micro-polished forged steel crankshaft casting 86G, forged connecting rods, and oversized hypereutectic pistons. SOHC 12-Valve cylinder head casting 72P features wide intake ports diamond-surfaced for multi-layer head gasket retention. Net dry weight totals 240 lbs within crated dimensions of 36in length by 36in width by 36in height. Crankcase oil capacity equals 4.3 quarts.

Key Features of Nissan KA24E

Professional automotive repair facilities buy Nissan KA24E remanufactured engine long blocks to restore work truck reliability and pass federal emission checks. This long block replacement provides factory-matched machine shop tolerances for mid-generation Nissan D21 pickups.

• Pre-installed front timing cover and oil pump assembly reduce shop turnaround and labor costs.
• Cylinder head casting 72P wide intake ports provide enhanced volumetric efficiency across mid-range RPM.
• Front timing cover features an 80mm distributor mount pattern for correct ignition distributor alignment.
• Crankshaft casting 86G journals receive micro-polishing to hold total indicator runout under 0.0003in TIR.
• Diamond plateau honed cylinder walls establish an Ra 16 micro-inch finish for piston ring seating.
• Align-honed cast iron main saddles support smooth crankshaft rotation under heavy truck payloads.
• Multi-layer cylinder head gaskets prevent combustion gas blow-by across resurfaced block deck surfaces.

Dyno Load Operational Tolerances Specifications

Dyno cell testing validates mechanical oil pressure and rotating assembly balance before crate shipment. The 2.4L 2389cc SOHC engine outputs 134 HP at 5,200 RPM and 154 ft-lbs of shaft torque at 3,600 RPM. 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 1992 to 1994 Nissan D21 Hardbody and 1995 to 1996 Nissan Pickup models equipped with the 2.4L 2389cc SOHC KA24E engine, wide-port head casting 72P, and 80mm distributor mount pattern. Compatible drivetrains include rear-wheel drive and 4-wheel drive paired with manual or automatic transmissions requiring bushing 12330-E3000. Fitment exclusions ban motorhome use, 1990 to 1994 narrow-port casting 40F engines, or 1996 to 1997 trucks with 100mm distributor mounts due to timing cover mismatch.

Installation Protocol Service Requirements

Technicians must measure distributor mounting ears to confirm 80mm spacing, install OEM transmission bushing 12330-E3000 on automatic applications, and burp cooling air pockets during initial setup. Operating warnings explicitly prohibit motorhome usage, overloaded commercial flatbeds, or custom turbo installations exceeding 6 PSI boost.

• Pre-fill the spin-on oil filter and prime engine lubrication passages with 10W-30 conventional motor oil.
• Drain initial break-in oil and install a replacement oil filter at the 500-mile maintenance mark.
• Recheck rocker arm mechanical clearances and verify ignition distributor base timing at 1,500 miles.
