Hey guys so im new here looking for some info. Im going to be putting a turbo on my 91 2.5l v6. I was wondering if anyone has an idea as to how much boost the stock internals can handle? I know stock compression is 9:0 so i imagine it isnt much but i was just peddling around. I know the 4cyl is desired buuuuut I'm different.

 

The range of 7 to 10 psi comes up depending what HP you are looking for.

A good number of information is on the net about adding a turbo to this engine.

 

ive searched but really only find things about the 3sgte not the 2vz.
