Acura CSX K20Z2 2.0L Remanufactured Engine 2006-2011

Description

Variable timing control screen clogging and tensioner ratchet tooth slip induce chronic camshaft phase miscorrelation across aging urban sedans. The Acura CSX K20Z2 2.0L Remanufactured Engine resolves timing correlation fault codes during commercial long block repower overhauls. This 4-Cylinder 155HP powerplant requires bellhousing alignment dowel projection verification before bolting transaxles flush against the engine block.

High-pressure die-cast A356-T6 aluminum forms the open-deck crankcase with centrifugal spun ductile iron cylinder sleeves. An induction-hardened forged steel micro-polished crankshaft rotates inside tri-metal bearings with high-strength powdered metal connecting rods. This Acura engine core demands a 12V 140A starter draw during cold morning rotations. Total dry weight measures 260 lbs within a 23in length, 22in width, 25in height base envelope holding 4.4 quarts of engine oil.

Key Features of Acura CSX K20Z2

Fleet maintenance supervisors buy Acura CSX K20Z2 2.0L Remanufactured Engine assemblies to restore vehicle dispatch rates without dealership delays. Our industrial engine rebuild standard replaces fatigued timing chain assemblies with pre-stressed links and hardened guide rails.

• Cylinder bore diameters measure 3.386in with diamond plateau honed finishes.
• Crankshaft main journal clearance holds at 0.0012in for immediate hydrodynamic wedge formation.
• Dual overhead camshaft lobes undergo surface profilometer testing to confirm factory lift profiles.
• Variable timing control phaser gears receive ultrasonic solvent washdowns to prevent spool valve contamination.
• Multi layer steel head gaskets lock compression pressure inside combustion chambers under high loads.
• This K20Z2 commercial core features cylinder head decks surfaced flat to 0.0003in.
• Stellite exhaust valve faces stop seat recession under sustained highway travel.

Dynamometer Load Verification Bench

Automated water brake testing certifies that this K20Z2 long block engine produces 155 continuous BHP and 139 ft-lbs of torque at 4500 continuous load RPM. Internal oil gallery pressure measures 54 PSI while oil sump temp levels at 192°F under full brake load. Exhaust gas temp tops at 1260°F down the test header tubes. Individual cylinder compression reads between 180 PSI and 188 PSI across all four chambers. Crankshaft center journal runout holds within 0.0002in TIR.

Field Installation Setup Boundaries

Electronic throttle pedal return spring mechanisms require 4 lbs of resistance force to guarantee predictable throttle return response at idle. This front-wheel-drive engine is not engineered for high-boost turbo drift vehicles, marine jet drives, or stationary generator pump skids.

• Drain initial break-in petroleum motor oil after 500 miles or 25 operating hours.
• Inspect cold intake valve lash at 0.009in and cold exhaust lash at 0.011in before initial road testing.
• Torque cylinder head fasteners to 29 ft-lbs then add dual 90 degree rotational passes in sequence.

Commercial Warranty Delivery Package

Backed by our rigorous Acura assembly standard, this remanufactured motor carries a 3-Year 100,000-mile limited parts warranty. The reinforced shipping crate contains the long block core, cast aluminum oil pan, front timing cover, valve cover, oil pump pickup screen, and a signed dynamometer validation document.
