It's a 13b turbo but I'm assuming it's a s5 since it's a turbo and not a turbo ii. Weren't the only turbo ii's s4's? Thanks. Pics are attache. I'm not near the motor but if you can tell from the pics I have that'll be great. Once again, thanks!

 

grats, you managed to find the only angle that gives the least amount of information to tell you if it is an S4 or S5.

if it wasn't a fuzzy pic i could tell you by looking at the secondary fuel rail, but i can't even make that out.


it does appear to be an S5 though due to the lacking EGR and turbo twin scroll.
