Hi there,
Hope you are doing well.
8115 rank in OBC Category is very high in case of JEE Mains paper 2.
Unfortunately, you won't be able to get into any of NITs or GFTIs or SPAs since most of them have a closing rank of at most 1000-2000 for OBC Category, but you can try for private colleges.
Hope it would help.
Thank You.
