hi new to site just bought impreza terzo and wont boost ?? have changed knock sencor as this kept popping up on most sites but still same can anyone help regards scott

 

could be few problems turbo boost solenoid check all pipes are connected intercooler pipes on properly

 

Hi mate , would help if you were a little more specific , have you no boost at all
These are a few of the common problems
1) leaks , check all pipe work , boost + vac
2) restrictor pill , is it in there ?
3) boost solenoid , is it working / give it a clean

 

Is there any boost or nothing at all
