This year seats are increased in JAC Delhi , even then I will not get biotech in NSUT/DTU ? My CRL is 149250 General Outside Delhi.
As per previous years records, it is quite difficult to get a seat in DTU or NSUT with this rank. As you belong to General category, outside Delhi, you cannot secure a seat as the cutoff is very high for the same for both of these institutes.
You can go through the following link to know the cutoff of previous years of JAC Delhi :
Hope it helps.
