Time we had one of these to refer to! Currently contains OEM + other combinations. Applies to the EA827 / EA113 engines, ie GTI blocks, short and tall, with some carry over to the 06A internal water pump designs, restricted by crank availabilty. Anything missing, let me know. Anything that can't be done, I'll remove the greyed numbers. Bore / stroke combinations Blue - OEM capacities Black - OEM parts or aftermarket parts Silver - theoretical, all subject to bearing diameters, rod dimensions & suitable pistons / end compression ratio.

This was in time superseded by the 94.5, the 90.5 ceasing as the 86.4 beame mainstream and the capacity race edged towards 2 litres+. 94.5 cranks were initially made with 46mm big end bearings to suit the 136mm rods on the 1588cc EG engine and similar. This later changed to 47.8mm to accomodate the 144mm rods of the DX-onwards. The Holbay crank was used in the UK by GTI Engineering, possibly to work around the fitment issue initially on early DX => cars. 99 + 100 cranks assumed to fit in bubble blocks only Bespoke racing combinations - parts generally unavailable, cranks certainly, and pistons prohibitively expensive due to gudgeon pin height Bore Stroke Crank pin 76.5mm 79.5mm 80mm 80.6mm 81mm 82mm 82.25mm 82.5mm 83mm 83.5mm 83.9mm 84mm 85mm Notes 88.1mm 46.0mm? 1998cc Audi A4 Touring Car 89.5mm 46.0mm? 1984cc Ibiza Kit Car 89.7mm 46.0mm? 1988cc Audi 80 Touring Car 90.0mm 46.0mm? 1990cc Golf Kit Car 92.2mm TBCmm 1996cc Skoda Fabia S2000 94.0mm ? 1998cc F3 Notes F3 Maximum bores / strokes - max bore or stroke fitments, for particular blocks - part complete, info appreciated!
