What are the top engineering colleges in maharashtra?

Indian Institute of Technology (IIT, Bombay) Powai

College of Engineering, Pune (COEP Pune )

Veermata Jijabai Technological Institute, Mumbai (JTI Mumbai )

Pune Institute of Computer Technology (PICT) Pune

Vishwakarma Institute of Technology, Pune (VIT Pune )

But i would suggest you if you want to do you shouln't limit yourself to maharashtra. You should extend your boundaries for other good colleges in other state like UTM in Shillong, UPES in Dehradoon, DTU and NSIT in Delhi and so on.
