http://www.team-bhp.com/forum/long-t...hlight=zen+mpi (1,47,658 km Zen Mpfi report + drift and slide pics) - had put up a report at 1.47Lac Km. The car has run almost 1.6L now. Engine wise, its still running strong, although we r facing some electrical issues.
Marutis are known to last for ages. I dont see why a well kept Zen wont do 2Lac Km without much issues
