In 2016, in case of Open Category , the closing rank was around 2,200 for Homestate and 400 around for Other State. For OBC , around 1500 for Homestate OBC ppl and 150–180 for Otherstate OBC ppl.

either way you shall prepare for the best and score more than 250 points!

all the best!

If you are aiming for CSE at NIT TRICHY and not having home state advantage then you need to score around 280 plus in JEE MAIN.
