Mazda 3 5 6 Tribute 2.0L L4 Engine 12818E 2006-2011

Description

Eliminate longitudinal oil starvation and rod knock with this precision remanufactured Mazda Miata MX-5 2.0L Remanufactured Engine. Production machine centers align-hone the aluminum block casting to true crankshaft bearing bores across the engine bay envelope. This 2.0L 4-Cylinder 16-Valve DOHC powerplant requires strict manual pre-lubrication of intake camshaft variable timing phasers before initial crank rotation.

High-pressure die-cast aluminum MZR block casting contains cast iron dry cylinder liners and an integrated structural lower bedplate. A forged steel crankshaft spins on upgraded tri-metal rod bearings clearanced to 0.0012in to prevent journal seizure. Aluminum DOHC cylinder heads house sixteen valves operated by mechanical bucket tappets and intake variable valve timing. Crated long block weight measures 252 lbs with crated envelope dimensions of 36in length by 36in width by 36in height and holds 4.8 quarts oil.

Key Features of Mazda MZR 2.0L

Roadster specialists buy Mazda Miata MX-5 2.0L remanufactured engine assemblies to restore sports car acceleration and crisp high-RPM response. Technicians install this remanufactured 2.0L long block replacement to end oil consumption and bearing failure.

• Aluminum block casting receives precision CNC deck milling to secure multi-layer steel cylinder head gaskets.
• Forged steel crankshaft journals undergo micro-polishing down to 0.0003in runout to eliminate high-RPM bearing friction.
• Intake variable valve timing oil passages receive ultrasonic cleaning to ensure instant camshaft phase adjustment.
• Tri-metal rod bearings maintain 0.0012in oil clearance to protect rod journals under high lateral acceleration.
• Plateau-honed cylinder sleeves seat replacement piston rings within 500 miles to eliminate oil consumption.
• Aluminum cylinder head castings receive CNC valve seat cutting to maintain 0.001in valve seat runout.
• Threaded brass oil gallery plugs replace standard press fittings to safeguard engine oil pressure under load.

Dyno Load Precision Machining Tolerances

Dynamometer testing confirms 158 HP at 6,700 RPM and 140 ft-lbs shaft torque at 5,000 RPM on our computer testing cell. Machine shop inspectors verify crankshaft journal runout below 0.0003in TIR while rod bearing oil clearance measures 0.0012in. CNC plateau bore honing holds piston-to-bore clearance at 0.0011in to prevent cold piston slap. Operating engine oil pressure sustains 58 PSI at 3,000 RPM with engine coolant stabilized at 192°F. Mechanical cylinder pressure gauges confirm balanced compression between 185 PSI and 190 PSI across all four cylinders.

Vehicle Fitment Drivetrain Guide

This remanufactured engine fits 2006 to 2011 Mazda MX-5 Miata roadsters equipped with the 2.0L 1999cc MZR LF-VE engine paired with Automatic Transmissions, alongside cross-compatible automatic Mazda applications. It mounts in longitudinal rear-wheel-drive configurations. This long block does not fit manual transmission Miata models with different crankshaft pilot provisions, 2.5L Mazda 3 engines, turbocharged Mazdaspeed platforms, or modern SkyActiv-G 2.0L roadsters.

Installation Protocol Service Requirements

Inspect longitudinal automatic transmission torque converter alignment and replace degraded engine bay motor mounts before securing the block onto the front subframe. Never operate this naturally aspirated sports car engine in forced-induction track projects without secondary baffled oil pans to avoid oil pickup cavitation. Mechanics must flush cooling circuits to prevent thermal air pockets.

• Pressure-prime internal oil passages with 5W-20 synthetic motor oil before starter engagement to protect camshaft bearing journals.
• Drain the factory break-in motor oil and install a high-micron oil filter at 500 miles.
• Inspect variable valve timing solenoid screens and check accessory drive belts at 3,000 miles.

Warranty Terms Core Return Policy

Our standard 3-Year Unlimited-Mile warranty safeguards internal long block components and machine shop labor against defects. We arrange free prepaid freight collection for your old engine core within a 30-day window. The crated package contains the complete long block core with timing chains, oil pan, and valve cover.
