Are the oil and water lines (all 4 lines) the same between a S4 and S5 car?

If not which lines are the same and which are not interchangeble?
Thanks,

Not sure if this will help....

I had a S5 turbo on my S5 car...I installed a S4 turbo using all the S5 lines...

Everything fit fine except on the oil return line I had to remove the heat sheild that cups around it as it comes out of the turbo.

Also, I had to get new heat shields for my S4 turbo because the S5 stuff didnt fit well.

i remember the water line on my s5 was bent to hell so i used my s4 and a little massaging and it worked okay, and i'm pretty sure the oil return doesn't work, but not positive. and wankel7 why did you put a s4 turbo on an s5?

Brian from BNR said he could port the WG larger on the S4...I hate boost control problems...so I thought I would give it a try.

Still breaking in the engine so I will get back to on how low I can keep the boost.

The oil returns lines are different, everything else interchanges.

S5 turbo is a good swap. Bigger wastegate, divided manifold. Picked mine up yesterday. Started work on new divided DP tonight.

Yep, oil drain on S5 is WAY longer.
It's obvious when you take a look at the connection to the front cover.
The hard metal pipe has to clear the larger electronic OMP.
