Hi Sayan,

According to both you general and obc ncl rank, it will not ne possible for you to get into any top NIT.

But, you have a slight chance if you are from the home state of lower NIT's like NIT,Hamirpur and NIT,Durgapur.

But, it will not be possible because for obc ncl you need to secure a rank of less than 15k.

Hope this helps and also refer to this link to check previous year cutoffs in NIT's-
