So Iv found someone to refurbish my turbos but he needs to know the exact turbos my car is running

I’m hoping for at Japanese import, 1996, TT manual 6 speed there’s only one option for turbos 🤞🏼

 

Can anyone tell me what turbos are on my car?

 

Thanks for your time

Think this is what you will have but can't accept any responsibility if yours is different. I took this data from another site years ago when I was talking to Nerings about replacement cores. Sadly despite an encouraging start they never came through.
