Mazda 3 5 6 MT 2.0L L4 Engine 12819E 2009-2011

Replace worn roadster powerplants with this Mazda MX-5 Miata 12819E Remanufactured Engine assembly. Built for manual transmission sports cars, this 2.0L 4-Cylinder 16-Valve DOHC long block produces dependable street revs. A mandatory trade-off requires an immediate pressure lube fill before initial startup to protect dry overhead cam journals against catastrophic metal friction during initial fire-up.

Cast aluminum block with cast iron cylinder liners. Forged steel crankshaft micro-polished to factory specs. Crated envelope dimensions measure 36in length by 36in width by 36in height. Dry long block weight registers at 252 lbs. Features a high-flow aluminum cylinder head with dual overhead camshafts, balanced forged connecting rods, and hypereutectic pistons with low-friction ring packs. Engine oil pan capacity holds 4.8 quarts of synthetic blend motor oil.

Key Features of Mazda 12819E

Independent shops buy Mazda 12819E remanufactured engine long blocks to restore factory sports car compression and emissions balance. This direct replacement resolves internal ring blowby across all 4 combustion chambers.

- CNC-resurfaced deck surfaces achieve Ra 30 smoothness to secure multi-layer steel head gasket retention
- Diamond plateau honed cylinder bores establish oil retention cross-hatching that seats piston rings within 500 miles
- Micro-polished crankshaft journals hold 0.0003in TIR runout to prevent bearing scuffing at 7,000 RPM
- Align-honed main bearing bores maintain 0.0012in oil clearance to preserve steady oil film thickness
- Upgraded multi-layer steel cylinder head gaskets eliminate combustion leaks during spirited gear changes
- Tri-metal rod bearings support dynamic rotating loads while resisting cavitation under road course conditions
- Remanufactured 16-Valve cylinder heads maintain 0.001in valve seat concentricity to optimize high-RPM volumetric airflow

Dyno Load Precision Machining Tolerances

Every remanufactured long block undergoes strict automated spin testing to confirm 167 HP output at 7,000 RPM and 140 ft-lbs torque at 5,000 RPM. Machine shop tolerances hold crankshaft journal runout at 0.0003in TIR with connecting rod oil clearances measured at 0.0012in. Plateau-honed cylinders show uniform compression between 185 PSI and 190 PSI across all 4 chambers. Hot engine oil pressure maintains 55 PSI at 3,000 RPM while regulated coolant temperatures stabilize at 192°F to confirm structural integrity before crate packaging.

Vehicle Fitment Drivetrain Guide

This remanufactured assembly fits 2009 to 2014 Mazda MX-5 Miata models equipped with the 2.0L 2000cc DOHC 16-Valve L4 engine and manual transmissions. Configuration requires factory 5-Speed or 6-Speed Manual drivelines paired with rear-wheel drive systems. Notice: this unit does not fit automatic transmission MX-5 chassis due to rear crank flange and flexplate register variations. It will not install into front-wheel drive Mazda 3 or Mazda 6 sedans because of block mount boss differences.

Installation Protocol Service Schedules

Align engine mount isolators before torquing bellhousing hardware to prevent chassis binding. Inspect throttle linkage and ground straps. Do not install this naturally aspirated engine into custom turbocharger projects exceeding 7 PSI of boost pressure without standalone engine management and race fuel.

- Fill crankcase with 4.8 quarts of SAE 5W-20 break-in oil containing zinc additives before manual priming
- Drain initial break-in oil and swap the spin-on filter after the first 500 miles of operation
- Perform subsequent synthetic oil and oil filter changes at regular intervals of 3,000 miles or 5,000 miles
