vw rule 19 Posted October 3, 2013 Hello there, I think the 9a and KR block are very similar, the 9a block flairs out a little more then on the KR lower down, as it has to hold the 2.0 crank shaft. Your block could be a early 9a block that hasn't been bored out to a 2.0 ?? Or the old owner before you had the car changed the engine from 1.8 over to the 2.0 ?? But yes the answer to your question is that you do have a 9a block in your car as that is the number 053 103 021B for the 2.0 (9a) engine block. I think the 1.8 (KR) block number is 027 100 101B Engine block number is on the front of engine just behind the dip stick tube. Late 1991 and early 1992 was the change over years from 1.8 16v over to 2.0 16v The 2.0 16v (9a) cylinder head part number is: 051 103 373 The 1.8 16v (KR) cylinder head part number is: 027 103 373 Cylinder head number is on the front of head slightly to the left near the top close to the top gasket lip, i.e where the valve cover gasket sits. I think that's correct. Hope this helps. Si Quote Share this post Link to post Share on other sites
