Hi

Let me display you the previous year cutoff tactics here:

Round 7 closing rank for Mechanical Engineering under Home State quota was - 8851(OBC Rank).

Special round 1 closing rank for Mechanical Engineering under Home State quota was - 38612.(AIR).

Special round 2 closing rank for Mechanical Engineering under Home State quota was - 40082(AIR).

CSAB Special Round cutoffs would be similar to this. According to this data, you have very low chances for Mechanical Engineering at NIT Surathkal. 

At this rank you can get the following at NIT Surathkal - 

Chemical Engineering (low chances).

Metallurgical and Materials Engineering

Mining Engineering.

You can always check the same about JEE Main Cutoff for NIT Surathkal in a greater detail through this link: https://engineering.careers360.com/articles/jee-main-cutoff-for-nit-surathkal.

Best of Luck. 

Hope this helps.

Cheers!
