Output rises to 142 hp in the 911T, 175 hp in the 911E, and 200 hp in the 911S.ġ972: North American emissions requirements again force change, this time to a lower compression ratio Porsche ups the flat-six’s displacement to 2.4 liters to make up for the lost power. The 911T continues to use Weber carburettors.ġ970: The new 2.2-liter flat-six is dropped into the 911T, 911E, and 911S the block is again magnesium and the basic aluminium head design is shared across the range.

A higher compression ratio, as well as changes to spark and cam timing and the carburettors, contribute to the added power.ġ968: The 911S is pulled from the U.S. Some may need new heat exchange plates this would be at an additional cost.ġ964: The 911 enters production with a 2.0-liter, air-cooled SOHC flat-six making 148 horsepower.ġ967: Porsche added the sportier 911S to the range with a modified 2.0-liter making 180 hp. The Camshafts are checked for wear and replaced as necessary. Refaced valves are re cut and the head is then leak tested. Valve guides are then checked for wear and replaced as necessary. Then the blocks, cylinder heads etc are vapour blasted in-house with our new VIXED 1215 AQUA BLAST MACHINE to bring them up looking like new.įrom this stage the cylinder barrels and pistons are checked, and rings are replaced, connecting rods and the crankshaft are then checked and polished.Īfter this the main and big end bearing shells are replaced, the oil pump reconditioned.Ĭylinder Heads are stripped down and checked for wear, cracks and for trueness. This removes all carbon deposits and debris from previous failures. The engine is stripped to bare components and put into a high-pressure cylindrical wash at high temperature with cleansing chemicals,
