• The k14 from the AAZ says .3  I'm not sur if the 1.6 eco turbo is any different.

• it's my understanding that only the cold side is different on the AAZ/eco k14s.

• The k14 and k24 both have the same .3 turbine A/R however that is the only common spec between the two housings.The T3 has the .36 A/R.

• While were on the topic the ko3 reads 3/1 which might mean 3.1 A/R and the T2 reads .35 AR.
  
  Using the turbine A/R to figure out which turbo is bigger/smaller is not the best way of figuring out which 1.6/1.9 turbo is bigger than the other.As you can see all of the 1.6/1.9 turbos have roughly the same turbine A/R and the only huge differences between the turbine sections are the wheel sizes and wheel trim.
