Im currently looking at a turbocharger on ebay but im unsure on how to understand on how to fully know of its rear exhuast size. How do you measure the rear A/R dimention, what part of the rear exhuast housing is this measurement done, along what, the length of the housing, the radius of the housing.

I found this in another forum:

6 cm2 = 0.41 A/R
7 cm2 = 0.49 A/R
8 cm2 = 0.57 A/R
9 cm2 = 0.65 A/R
10 cm2 = 0.73 A/R
11 cm2 = 0.81 A/R
12 cm2 = 0.89 A/R


What sort of sizes do the td05h turbos have.

Now, where on the turbo do you do the measuring up.

Hope to get some insight asap.
