Before I start, let me try to avoid any confusion before we get into it.

The car is an S4, into which I swapped and S5 engine, and left the S4 intake (LIM,UIM) on it, with the LIM modified to fit the S5 ports.

Now, I was unaware that the S5 intake could be used in the S4, due to differences in the TPS and other assorted items. Zerkster told me that I could have used the S5 intake. I searched for some info about it, but was unable to find anything because the search function would not let me use the word S5, lol.

I'm just wondering what I have to acquire/modify/do to use the S5 intake on my S5 engine in my S4 car.

Lol... lotta S's in there. Hopefully you guys are following.

 

How is the wiring set up right now?

 

^ That's a good question. I am guessing S4 wiring.

Either way here's one writeup.

Yea, theres no change to the wiring, as I'm using all S4 intakes and sensors. Just an S5 block.
