Review MG Engine 2912cc Mgc Essentially Complete fits 1967–1969

Introducing the 29ga engine, a powerful and iconic component of the MGC cars produced between 1967 and 1969. This engine, specifically a 2912cc unit, is a testament to the engineering prowess of the British Motor Corporation during that era.

The 2912cc engine, also known as the XPEG unit, is a straight-six cylinder powerhouse. Its all-alloy construction makes it not only robust but also relatively lightweight for its size. The engine block features a cast-iron sleeve liner and a crossflow cylinder head, which facilitates efficient cooling and scavenging of exhaust gases.

The 2912cc engine boasts a complex induction system with twin SU carburetors, each with a capacity of 1.75 inches. These carburetors allow for a generous fuel supply, ensuring the engine delivers ample power and torque across the rev range. The engine's compression ratio is a healthy 9.5:1, providing excellent combustion efficiency and responsiveness.

The engine's camshaft is driven via a double overhead camshaft arrangement, which not only allows for more efficient valve timing but also adds to the engine's distinct sound. The engine's valves are operated via a hydraulic system, ensuring precise and reliable valve control.

The 2912cc engine is known for its smooth and refined power delivery. It produces approximately 170 horsepower at 5,800 rpm and 181 lb-ft of torque at 3,400 rpm. This power output translates to an exhilarating driving experience, with responsive acceleration and a top speed of around 125 mph.

Maintaining the engine is relatively straightforward, thanks to its accessible design. The oil filter and air filter can be easily accessed from the front of the engine, while the timing chain and water pump are located at the front of the engine block for convenient servicing.

In summary, the 29ga engine, specifically the 2912cc XPEG unit used in MGC cars from 1967 to 1969, is a masterpiece of British automotive engineering. Its powerful and refined performance, coupled with its robust and accessible design, make it a favorite among classic car enthusiasts and collectors.

Buying a 2912cc (approximately 1796 cubic inches) 29-inch engine for a 1967-1969 MG Midget or Coupe (referred to as MGC) comes with several pros and cons. Here's an in-depth analysis:

1. Power: The larger displacement engine provides more power compared to the standard 1275cc engine. This results in better acceleration, smoother cruising, and overall improved performance.

2. Customizability: A larger engine offers more opportunities for customization and tuning, which can be appealing for enthusiasts.

3. Vintage Appeal: A more powerful engine can enhance the vintage appeal of the MGC, making it a desirable collector's item.

4. Bragging Rights: Owning a car with a larger engine than most of its contemporaries can be a source of pride for some.

1. Cost: The cost of acquiring, installing, and maintaining a larger engine can be significant. This includes the cost of the engine itself, any necessary modifications to the car, and increased fuel consumption.

2. Complexity: A larger engine is generally more complex than a smaller one, which can lead to more maintenance issues and increased repair costs.

3. Fuel Efficiency: The larger engine consumes more fuel than the standard engine, which can lead to higher operating costs.

4. Weight: The larger engine adds weight to the car, which can negatively impact handling and fuel economy.

5. Compatibility: Not all MGC models are compatible with the 2912cc engine, so it's essential to ensure the engine is suitable for your specific model.

In conclusion, the decision to buy a 2912cc engine for a 1967-1969 MG Midget or Coupe depends on your priorities as a car owner. If you're looking for improved performance and don't mind the increased cost and complexity, then a larger engine may be worth considering. However, if you prioritize fuel efficiency, low maintenance costs, and originality, then it's best to stick with the standard engine. Ultimately, the choice is a personal one and depends on your preferences and budget.

Details:

It is sitting on a pallet so I cannot turn over the engine. Please message me if there are other photos you would like. Based on a plate stamped 29GA / R c2848 it appears to be 2912cc engine from '67 '69 US-market MGC. I removed the plugs and used a bore scope to see very clean bores, no scoring or wall damage, moisture present.

It has the full block, heads, distributor, oil filter housing, valve cover, torque converter, intake manifold with SU carbs, exhaust manifolds, water pump and some hoses. It is quite heavy so I think this probably correct. I have some pictures posted but you can see the engine is remarkably complete.
