Hi there,
well, the rank predictors don't work for your EWS rank currently as there has been no EWS rank in the previous years.
But with your general category rank here are the courses that you can get in the top NITs( Considering your home state to be Delhi):-
1) NIT Trichy:- No branch available
2) NIT Surathkal:- Mining Engineering
3) NIT Warangal:- Biotech Engineering
4) NIT Calicut:- Production and Biotech Engineering
5) MNNIT Allahabad:- Biotech Engineering
6) SVNIT Surat:- Integrated MSc. Physics/ Chemistry/ Mathematics

Hope it would help.
All the best.
If you have home state quota for any of these NITs, mention it in the comment section.

You will not get top 5 NIT but As per your rank and previous year cutoff, the colleges or NITs you get are:-

NIT Patna

IIIT Trichy

NIT Sikkim

NIT Durgapur

NIT Calicut
