Done for the future reference of all engine gurus worldwide. Should answer all questions in respect to how far out the 2.0l block can be taken to. Here we go now, enjoy! Engine code 6A. Green surfaces are VW factory faces, red surfaces are my own cut surface ground faces. And the all important measurements> Bore 82.50mm Stroke 92.80mm Average wall thickness of block through out(non high load areas)> 6.00mm. Distance between bores taken with a high quality vernier callipers> 5.72mm. Average main oil way gallery's diameter> 12.30mm. Oil feed to head, average diameter> 5.60mm. Distance from bore wall to root of oil squirter thread> 3.20mm. (''root measurement'' as in root of the thread of banjo bolt that holds squirter in place) Minimum bore wall thickness> 4.44mm, max 7.80mm. Average deck thickness, pretty uniform throughout>minimum measurement> 16.00mm Bridge piece across water passage at number 1 and 4 cylinder> 10mm high x 17mm wide. Block featured is a standard bore 2.0L 16v 6A external water pump forged crank(this had one?) type block with approx 150k miles. I hope these pictures and specs help everyone who is thinking of or in the process of building a great engine. I also hope these pictures will put peoples minds at ease with any doubts they may be having when it comes to boring these babies out or planing the deck, tapping oilways for remote supplies, dry sumping,etc. Points to note are> The bridge across water passage which is not in the 1.8T block as seen in the 1.8T section. The mould bridge stabiliser seen between the 2 cylinders, fitted at time of casting to aid stability to cores im sure. The general beefiness of the entire block compared to the AUG 1.8T. Casting is solid between main bearing carrier and base of bore. I stand by all of the above measurements.
