Performance engine

In June 2008, at 152.000 miles, a rebuilt T7 engine block by MapTun has been fitted. The cylinders have been drilled to 90,5 mm with a very smooth surface, and the block has been equipped with Wössner forged pistons.







The original cylinder head has been gas flowed by Johann Heuschmid (intake and exhaust ports polished, valves polished, seats ground, valves ground in), and 8 new exhaust valves have been installed.
