My JEE Mains paper 2 percentile is 83.002 (OBC). Is there is any chance to get an NIT?

It is not possible to get admission in NIT's with your percentage, just apply for private colleges.

With this percentile, I must say it is almost impossible to get admission in NITs even with your OBC category also. It is better to apply for some other colleges. Bust still I will say do not lose hope. You can try Shiksha's college predictor also to get a better idea.
