How can you tell just from the engine if it is a S4 turbo or S5 turbo? is there a code that I could look up? I looked in the FAQ section but didnt really see anything regarding this, just the difference between s4 and s5.

 

Are the accessories on the engine? I think (but I'm no expert) that the oil metering pump is different between the two models. The mechanical OMP on the S4 will have a linkage rod running from the lower left front side (looking from the front) up to the throttle body. The S5 has an electronic pump and won't have the linkage. Also, I think that the pulsation damper and the throttle position sensor design are different.

 

Perity much the S5 UIM look different the TB has a linkage rod the motor will have an electric OMP and not manule. The TB will have 2 TPS's on it. The turbo will have TS and the motor will have a TS silinoid on it. It is green in all th way to the front of the silinoids.

 

interesting, any idea with the pic?

 

S5

 

from the plastic thermostat thingy, right?

 

Ahhh no. That sould still be galvenized aluminum with a RAD cap.

From the OMP

 

awsome, i thought it was S5 too, I need to buy a flywheel before i do the swap
and i think i need a driveshaft too, but thanks for those of you that replied!!

 

S5 for sure.

some easy differences.

- TPS. S4 are single. S5 are dual.

- Thermostat neck. S4 are metal two bolt. S5 are plastic three bolt.

- OMP. S4 are mechanical with a metal rod. S5 are electrical with no rod.
