Hey,

See this is difficult to predict the ranks will differ year to year. Basically KEA uses PU and KCET socres in equal ratios but there are other factors that make a difference like the number of applicants, So a large number may mean that ranks wont be the same. also you have to consider the number of students who may have obtained the same marks and inter-se-merit rules are applied. So predicting is pretty dicey. However something like 150 to 180 should fetch you a good rank. 

The best colleges that come under KCET are:

MS Ramaiah Institute of Technology, Bangalore

BMS College of Engineering, Bangalore

Siddaganga Institute of Technology, Tumkur

PES University, Bangalore

KLE Technological University, Hubli

Dayananda Sagar College of Engineering, Bangalore

BMS Institute of Technology and Management, Bangalore

Bangalore Institute of Technology, Bangalore

Vidyavardhaka College of Engineering, Mysore

University Visvesvaraya College of Engineering, Bangalore
