what turbo is this?
 

I know this turbo is not stock, but does anyone know what turbo this is exactly.

The only thing I have to go buy is the number that was on the turbo. It is...

5k2745ht18s-23

The very last number is either a "3" or an "s"

Thanks for any help.

im pretty sure thats an S4 turbo from the -23....HT18 is the turbo FC's came with. If you can see the turbo..if the wastegate arm is bent, its an S5, if its straight, its an S4

OK, thanks.
