Unfortunately you won't be getting any Indian Institute of Technology or National Isntitute of Technology as your rank is sadly too low for them. Even in the Scheduled Cast category, the cut-offs of the north-eastern NITs close around 8,000 to 9,000. However you can get admission into other good colleges like:

SRM Chennai
VIT Chennai
VIT Bhopal
HBTU Kanpur
KNIT Sultanpur
