seaco Posted September 7, 2005 Report Share Posted September 7, 2005 Hi Quick question does anyone know what the standard bore size would be on a 1.8 KR shortblock MK2 16v GTi I have been told it's 87.5mm does anyone know if this is correct? I have been offered a 1.9 KR block and I need to be able to check that this is the case? Thanks in advance Lee Link to comment Share on other sites More sharing options...
Tobes49 Posted September 10, 2005 Report Share Posted September 10, 2005 Dont know why but 81mm springs into my head! but that is a total guess, but I can remember you need a 1.5mm over size piston to take it 1.9! Link to comment Share on other sites More sharing options...
