The ABA is 16mm taller, substantial by engine dimension standards. The rods are also 15mm longer. The VW I4 continued to use the same head bolt and exhaust manifold pattern until it was replaced in 2010, they also dropped back down to the original deck height after the ABA in 1999. But those motors are considered different because they went to coil pack distributor-less ignition and chain drive oil pump(no intermediate shaft).

B Heck, I forgot about the extra few milometers of block height they added to take the displacement up to 2 liters.....but the engine block castings, the head bolt pattern, the exhaust manifold bolt holes, etc....those were essentially interchangeable from the first generation of inline four VWs till they changed around 95-97....Many of the early parts areB interchangeable without issues, some require slight modifications.B B The taller ABA block was not a problem to fit into my engine compartment but the clearance is tighter.
