I will admit it, I'm a turbo noob. I wan't to know what do the letters a/r compressor, and a/r turbine mean? There is also another number something to do with trim. What do these numbers mean and how do they affect the boost ranges and the lag of a turbo? I want to turbo my ls but I only know the basics of a turbo. I am going to school to be a Honda tech, but unfortunately they don't go into forced induction that much. I am really just looking for some Honda-tech-ers to give me a hand and walk me through this turbo ****. I do realize that there are many sites to learn about turbos but I figure that you people with the hands on experience can help me better, but I am still searching and trying to learn. Thanks for the help.

 

I learned alot off these two sites...
