There are indeed five NITs(earlier RECs)worthy of becoming an IIT with their huge brain pool and good infrastructure. All the top 5 NITs- Trichy,Surathkal,Allahabad,Calicut and Warangal-have very good infrastructure and faculty line-up. Make them IITs and they are sure to reach the other IITs' standards amazingly fast.Owing to the fact that India is rapidly becoming a superpower in the knowledge field, we need to set up more IITs so as to continue to be the best.
