What would have to go into swapping out a s4 turbo for a s5 one? I know that I would need the s5 manifold, and I have read the oil lines are different. What is different about them? Would I need to swap in anymore parts, or can the conversion be done with the stock lines?

 

S5 turbo + S5 exhaust manifold. All of the S4 lines get bolted to the S5 turbo. The drain line is different because of the front cover connection point.

 

i did mine just fine, just swap the s5 manifold too and youre good to go!

 

I would also add that the coldside of the turbos are the same. So if you have 2 turbos use the coldside with the least shaft play. If the turbo hasn't had the wastegate enlarged then the turbo is going to have to come apart anyways.

 

the only thing different is the turbine housing and manifold. Everything else is identical. Even the turbine and compressor are the same...
