I have a 2005 impreza 2.5 rs. I am or will be ordering a turbo kit for it from xcceleration.com. THe only problem is I have heard that if you put a turbo on a non-turbo 2.5 engine that it starts to have all kinds of problems and the check engine light comes on and everything. so if someone could give me some details on how my engine would handle this mod I would appreciatte it.

 

What exactly comes with this kit? I mean not to get in to the whole fact that your block wont be able to handle that much boost. Your check engine light will come on if you touch something that you shouldnt, if you let me know what parts exactly you will be messing with than i might be able to tell you which will cause that light to go on.

im only goin to be running the turbo at 5 psi so Im pretty sure this engine can handle it. I talked to the subaru dealership and they said these engines are built to handle a turbo. they told me that the same engine is in the forrester xt with a turbo and it handles it fine

 

It is not the same engine(EJ25,EJ25T). They do share the same displacement but the internal parts of the motors are completly different.

 

the biggest concern that I have is.. The ej25 is an open deck motor....
