About 48 months after picking up the S4 Avant from a fellow Audi enthusiast they contacted me offering to buy the Avant back if I ever was thinking of selling it.

As it turned out I had not been driving it very much. I’d picked up a Mk7 GTI as a daily driver to replace my Miata. The Mk7 GTI is very similar to the S4 with respect to exterior dimensions and comes in a few hundred pounds less weight.

The turbo engine and abundance of aftermarket parts options were another bonus, offering the opportunity to test with a different platform.
The opportunity to return the Avant to the previous owner made the decision to see it off easier to make.
First though there would be a final turbo swap, removing the Frankenturbo F21 v3’s for a pair of TiAL 605s’.

Knowing this would likely be the last time I was removing a 2.7T engine made it a bit easier to undertake what is probably the dozenth engine pull I’ve worked through.

Swapping turbos to the TiAL 605.

The engine only has about 50k on it, but having it out I took the opportunity to replace a few coolant hoses that have been in use for a number of years.

Back in it goes.

Nearly done…

With the Avant back with the prior owner and the GTI a family favorite daily driver a replacement project car was needed. The Mk7 Golf R was what I settled on. Similar to the B5 S4 but with enough differences to launch a new round of tests at MyGolfMk7.com
