Hi . It would have been better if you had stated the rank but I can still give you a general idea about it. If your rank is in top 500 ,then you can easily get an architecture seat in top NITs. like SPA Delhi, NIT Trichy . As far as I know, for general students 250+ marks is the minimum marks required to get into a NIT. And if you are an OBC student then 215+ marks will be enough. So, I doubt you won't get a seat in NITs or SPA.

Regards.
