Gangjee, who came in through the Qualifying School at the start of the season, is now three-over 147 and in tied 17th place, while Kapur at five-over 149 is tied 39th.
With the starting field of 132, only the top-50 and ties made the cut with 51 going through for weekend action. Sam Cyr of the United States returned with a three-under-par 69 to snatch the second round lead from Australia's Scott Hend today.
Kapur, starting on the tenth, struggled through the stretch with one birdie, two bogeys and a treble on 18th. But he parred the remaining nine, the front stretch of the course and carded 76.
Gaganjeet Bhullar (74-76), Himmat Rai (76-74), Anirban Lahiri (79-72), Ajeetesh Sandhu (76-78), Sujjan Singh (82-72) and C Muniyappa (81-79) missed the cut.
Cyr, who finished tied-ninth in last year's edition, was clearly determined to do better as he compiled a two-day total of five-under-par 139 to take a two-shot advantage over Hend, who had earlier grabbed the clubhouse lead with his 72 at the Taiwan Golf and Country Club.
