Complete set of Mahle forged stroker 94mm Long Stroke barrel and pistons.
These are designed for use with crankshafts of 76mm and above. 
Example 94mm piston kit x 82mm crankshaft = 2276cc. 
Stroker barrel and piston sets are designed to make engine assembly easier when fitting larger stroke crankshafts.  By using this type of barrel not so many barrel spacers will be required when doing final set up of deck height and compression ratio.
