Ok, i just bought an s5 turbo motor. It has the electric mop, and all the other stuff that an s5 has normally,but heres the kicker. I removed the turbo and manifold, and found that it has the seperate holes for each bank (where the turbo joins the manifold, but it has only one wastegate flapper. I was told that the s5 turbos have two flappers. So, how do i tell the diff....did some idiot in japan put an s4 turbo on this s5?


Thanks in advance

 

The S4 has a actuator on the manifold for the twin scroll. To view the flappers pull the plate off on the end that connects to the downpipe.

The S5 turbo has one big flap that covers two wastegate ports.
