S4 turbo question
 

So the corner of the flange cracked and broke off on the hot side of my turbo. I was wondering if i used an S5 turbo and manifold, would everything bolt right up? :scratch: From what I have been reading is that it should with some light modifications to the twin scroll? Im new to the rotary world so any help would be much appreciated

it will bolt up as long as you have the matching oil and water lines

alright...looks like i have to find the lines then. whats the difference between the s4 line and s5 line?

New lines aren't needed. Just swap your S4 lines over to the S5 turbo.

You will need the S5 wastegate actuator, so make sure the new turbo comes with it.

The turbo to manifold gasket is also different.

The s4 twin-scroll hardware comes off with the manifold and you just need to cap the vac line feeding it.

ya, my mistake. i meant to say that you have to keep the old lines

thanks guys for our help. ill be tackling this problem this weekend
