M96.03 3.6L Porsche 911 996 Engine Rebuild Kit (Standard or Deluxe)

Description

Porsche 996 3.6L M96.03 Engine Rebuild Kit

This Standard or Deluxe RND engine rebuild kit is specifically designed for the 3.6-liter M96.03 engine used in 2002-2005 Porsche 911 Carrera 996 models, 2002-2004 Carrera 4 models, and 2002-2005 Carrera 4S models. A successful M96 engine rebuild involves much more than replacing pistons, cylinders, bearings, and head gaskets. The cause of the original failure needs to be identified, cylinder condition must be corrected, and the engine’s other known weak points should be inspected and upgraded while the engine is already apart.

If you are rebuilding a different M96 or M97 engine used in a Boxster, Cayman, 996, or 997, visit our complete RND Porsche M96/M97 engine rebuild kit catalog to select the correct kit for your engine.

Before planning your rebuild or ordering parts, review our Ultimate Porsche M96/M97 Engine Rebuild Guide for a comprehensive look at what should be inspected, replaced, upgraded, and considered during the rebuilding process.

Complete Porsche M96 Engine Rebuild Parts, Services & Reliability Upgrades

RND engine rebuild kits simplify parts sourcing by bundling the commonly required hardware, bearings, seals, gaskets, timing components, and related rebuild parts in one package. But LN Engineering can also provide the specialized parts, machine work, inspection, and reliability upgrades needed to address the rest of the engine while it is apart.

• Nickies cylinder sleeving and bore repair: M96 and M97 Lokasil cylinders can suffer from bore scoring, cracking, slipped sleeves, and other cylinder failures. Our M96/M97 Nickies cylinder repair and sleeving program replaces the original cylinder structure with aluminum nickel-silicon-carbide plated sleeves for a permanent repair and performance upgrade.
• Intermediate shaft inspection and IMS upgrades: We can inspect the intermediate shaft for runout, recondition it when appropriate, pin the main drive sprocket, and install the correct IMS bearing or upgrade for the application.
• ARP hardware and fasteners: Upgraded ARP connecting rod bolts, crankshaft carrier through-bolts, cylinder head studs, and other hardware can replace torque-to-yield or failure-prone factory fasteners while the engine is apart.
• Connecting rods and coated bearings: ARP rod bolts are recommended for street rebuilds, while larger-displacement, track, or higher-output engines may benefit from upgraded connecting rods. Coated rod and main bearings can add protection during startup, break-in, high-load operation, and boundary-lubrication conditions.
• Oil system upgrades: Deep sump kits, oil-pan baffles, spin-on oil filter adapters, magnetic drain plugs, and other oiling upgrades can improve protection for spirited street and track-driven cars.
• Cooling system upgrades: A low-temperature thermostat allows the cooling system to begin regulating earlier, while upgraded radiators can provide additional cooling capacity where required.
• Billet reliability upgrades: Billet tensioner paddles, chromoly oil-pump drives, underdrive pulleys, alternator mounts, and other upgraded components can replace known wear or failure-prone factory parts.
• Flat 6 Innovations-developed upgrades: Select reliability upgrades originally developed for Flat 6 Innovations M96/M97 engine builds are available for qualifying rebuilds.

Porsche M96/M97 Machine Shop & Engine Preparation Services

LN Engineering can also perform the detailed preparation work that separates a basic parts replacement from a properly blueprinted Porsche engine rebuild. Our Porsche engine machine shop services can support both professional engine builders and individual customers with specialized inspection, machining, and preparation work.

• Piston ring end-gap setup
• Ring light checking and ring-tension measurement
• Piston and connecting rod balancing
• Dynamic engine balancing
• Crankshaft magnaflux inspection and polishing
• Porsche cylinder head reconditioning and rebuilding
• Custom head gaskets for larger bores or resurfaced decks
• Engine blueprinting and dimensional inspection

Nickies solve the cylinder problem, but the complete engine package addresses the rest. When an M96 or M97 is already disassembled, it is the best opportunity to correct known weaknesses, replace wear items, and build in additional reliability before the engine goes back together.
