what is the most common turbo that is being used on an 03 lancer. kinda curious so i know what to keep my eyes open for if i come across one. thanks

 

Depends on the setup. The best setup to me would be a gt28r or t3s60. They both will make power by 3k and hold it to redline. Plus when the time comes, it can push you into the 250-280whp range on pump. Can do ~300whp on race/93 and wmi.

Other people like to use a 16g or T25/T28

 

Please search, there is an entire forum dedicated to turboing the lancer.
