Porsche 997 M96 engine for sale
Product Overview
For sale is a complete Porsche 997 M96 3.6-litre flat-six engine paired with its original 6-speed manual gearbox, offered as a single, ready-to-install package. This is a strong-running, well-presented drivetrain unit that has been assessed and is reported to be in sound mechanical condition throughout — making it a highly practical acquisition for a direct replacement, project build, or engine conversion application.
The engine runs cleanly with no unusual noises, no smoke even on cold start-up, and excellent oil pressure. The clutch does not slip and engages correctly, and the gearbox shifts smoothly and positively through all six ratios. For a used Porsche flat-six drivetrain of this generation, this level of reported health is both reassuring and relatively uncommon.

Condition
This drivetrain has been assessed in running condition and presents well across all key indicators. Specific observations are as follows:
- No unusual engine noises — no bearing knock, tapping, or mechanical roughness reported at any point in the rev range
- No smoke on cold start or under running conditions — a positive indicator of piston ring and valve stem seal integrity
- Excellent oil pressure — consistent with healthy bearing clearances and a functioning oil pump
- Clutch in good condition — no slipping under load; biting point and engagement behaviour reported as normal
- Gearbox shifts smoothly through all gears— no baulking, crunching, or false neutrals reported on any ratio
Collectively, these are the indicators that most reliably reflect the mechanical health of a used M96 drivetrain and suggest this unit has been reasonably maintained and is not in a state of advanced wear.
IMS Bearing – Important Buyer Information
It is strongly recommended that any buyer — whether purchasing for a direct swap, project build, or conversion — arranges for the IMS bearing to be inspected by a qualified Porsche specialist at the earliest opportunity, and considers replacing it with the widely available and proven aftermarket IMS bearing upgrade solution if this has not already been carried out.
The IMS bearing upgrade is a well-established and cost-effective procedure when performed as a planned maintenance item. It is considerably less so when carried out as a consequence of bearing failure. This information is disclosed in full and in good faith to allow the buyer to make an informed purchasing decision and to plan the necessary work accordingly.
Ideal Applications
This complete M96 engine and gearbox package is well suited to a range of applications:
- Direct replacement swap — for a 997 with a failed, worn, or damaged M96 engine requiring a running replacement unit
- Porsche 997 project or restoration build— ideal for a stripped or non-running car requiring a drivetrain
- Porsche Boxster engine conversion — the M96 platform shares significant architecture with Boxster applications and this unit is suitable for conversion builds
- Kit car or bespoke vehicle build — the flat-six configuration and compact dimensions make the M96 a popular choice for custom and specialist vehicle projects
- Track or club motorsport build — a sound, complete unit at a practical price point for competition car preparation
About the Porsche M96 Engine
The Porsche M96 is the water-cooled flat-six engine that replaced the long-running air-cooled series in the 996-generation 911, continuing through the 997 generation. It marked a significant technical transition for Porsche — introducing liquid cooling, four-valve cylinder heads, and VarioCam variable valve timing to the 911 platform for the first time.
In 3.6-litre specification as fitted to the Porsche 997 Carrera, the M96 produces 325 horsepower and 370 Nm of torque, with a characteristically smooth and progressive power delivery that has made it well regarded among both road and track drivers. The engine is noted for its mechanical refinement, responsiveness, and the distinctive sound of Porsche’s horizontally opposed configuration.
The M96’s primary known weakness — the intermediate shaft bearing — does not diminish the fundamental quality of the engine design; when the IMS bearing is addressed and the engine is otherwise in sound condition, the M96 is a thoroughly capable, durable, and rewarding powerplant. This makes well-maintained and correctly prepared M96 units a genuinely attractive proposition for project and replacement use.
