While I am waiting on some additional parts to be able to commence installing the K04 turbochargers on this S4 I have been directing my efforts at refreshing and upgrading the suspension and brake components. The past couple of days I’ve been working in the driver side front wheelwell.
Today I wrapped up a bunch of parts swaps.
Starting at the bottom and working the lines counter-clockwise we have:
- Both lower control arms (balljoint on the front was a blast trying to get out.)
- Swaybar end link
- Brake rotor
- Vogtland Coilover (Had to visit Autozone to borrow a spring compressor)
- Brake pads
- 034 brake line
- Tie rod end (Surprisingly pesky putting the new one in)
- Upper control arms (Neither went in willingly)
The turbochargers have arrived. I was mistaken about them being Genuine BorgWarner, they are a K04 rebuild from Midwest Turbo Connection.
Next up will be to check and set the preload on the wastegates to 8 psi so I can take a short break from the suspension and brake work.
I have those same turbos and one of the plugs on the turbo for the coolant was leaking, make sure there are no loose bolts or anything like that, I had a bad leak at first. Other than that, 5k miles in at 21psi peaking at 23-24, no issues yet.
Thanks for the heads-up about that, I’ll be sure to look them over closely. They look like a well built turbo, the wastegate looks solid, not what I was expecting, but pleasantly surprised by that.
