Ok so I have this turbo in my 2003 wrx and have no idea what kind it is and there is no writing on it. It's smooth and shiny through out. The car has catless up and down pipe. Also cams too. I'm tuning the car and don't know how much boost I need to push

 

40 psi should do you good

 

Most people think it's not stock when they see it but don't tell me what it is

 

Haha funny. No but really. I only have it at 13psi to be safe

 

take a pic of the setup

 

it's a ihi turbo. Thats about all i can see from the pictures

 

here are some pics

 

so i looked around and someone said i have a TD04 that might of been worked on and polished. does anyone else know for sure? and how can one know? thanks
