So I landed a free s5 car that I will be using to revive my s4.

My question is this, what is the all-inclusive list of things I will need to pull off of the s5?

I know I will need the keg, the intake manifolds, the tranny, wiring harness, ECU...

What is EVERYTHING that is needed for the swap? I don't want to be left with not having everything I need...

Also, if anyone personally has done this - what was it like? Any advantages? Any hardships you ran across?

 

Rotary Resurrection: Swapping an '89-'91 S5 Engine into an '86-'88 S4 Car

 

So this also applies when swapping an S5 T2 into an NA S4?

 

^ That complicates things.

You need parts of a S4 13BT in order to use a S5 13BT... You're trying to get the car to believe that you're running a S4 engine. The S5 13BT has a superior rear iron, turbo wastegate passages, and divided turbo exhaust manifold. The easiest thing to do is to stick to your specific series.

 

Yeah I saw a build thread relevant to my question, saw that it wasn't the swap I thought it was. Think I'll just save for a '89 TII.
