Product Description

For sale is a Porsche 911T Type 911/57 flat-six engine, rebuilt to a displacement of 2.8 litres by South African car builder Dutchmann.

The engine was originally removed from a 1969 Porsche 911T and manufactured with a factory displacement of 2.4 litres. It is believed to have subsequently undergone an earlier rebuild using RS-specification components, increasing its displacement to approximately 2.7 litres. In 2020, Dutchmann completed another rebuild, increasing the displacement to 2.8 litres.Porsche 911T Type 911/57 Engine

The rebuild included machining the magnesium engine case, which was skimmed and line-bored. A crankshaft with standard-size journals was installed, together with resized connecting rods fitted with replacement bearings, nuts and bolts.

The engine features 92mm JE pistons, S-variant camshafts and replacement bearings, connecting rods and crankshaft. Its engine case carries the serial number ☆6530429☆, corresponding to a 2.4-litre Type 911/57 flat-six originally produced for a European-specification 1972 Porsche 911T equipped with Zenith carburetors.

This engine offers an interesting specification for Porsche classic-car enthusiasts, restoration specialists and collectors looking for a modified air-cooled flat-six. Buyers should review the rebuild history, engine identification and current mechanical condition before purchase.
