Threads on putting an S5 turbo on an S4.

I know you can do it, but that damned search feature won't let you search for anything with less than three letters, so S4 and S5 are out. Someone wanna point me at some threads about doing this?

And before I start seriously considering this project, are the benefits really worth it?

You need to plumb the wastegate line directly to the wastegate - the stock Kouki cars run a boost solenoid, so this needs to be capped or bypassed; the Zenki cars have no boost solenoid control.

The oil outlet pipe is slightly different, so you need to address this problem - I think you can swap the oil outlet pipe from a Zenki turbo to make it fit?&nbsp This might not clear some parts of the turbo?

Reted is correct, I just did this a couple of weeks ago! Everything on the s4 turbo as far as lines go can be swaped with the s5! Just be sure to get new crush washers for the oil lines, I tried to reuse the old ones and developed a small leak!
