Hi madan ,
With a rank of 2000 in jee paper 2 you can get some nits for barch, with a rank under 1500 you can get admission to most nits and with three digit rank like 500 you can get all nits .

But this is condition acoording to your all india rank .
But as your category rank your rank should be below 3 digit rank to get admission into nit with barch.

Hope it helps!!!
