It is very tough for you to get into any NIT with your common rank list rank of 138998 but can surely get into one with your SC category rank in the newer NITs.

Do try in the following nits

NIT Meghalaya

NIT Goa

NIT Andhra Pradesh

NIT Raipur

NIT Agartala

NIT Shillong

I suggest you also try for the IIITs as they are equally good as some NITs and can fit in easily with your rank. Best of luck
