Great sounding build!

As a fellow twincharged CTH fan, I'll follow along with interest.

My little A1 is grossly over-capitalised, but I love it.

The best bang for buck thing I've done of all the mods in my signature? The SuperPro dog bone insert - for < $100 the transformation was amazing. It cleared up so much axle tramp (maybe not ideal for a family car... I dunno).

The silliest thing? The Quaife DQ200 LSD. Haha. I mean. It's great now it's in there but that was a $5000 journey I don't know if I could ever whole heartedly recommend to others.

I'm most interested in what you're up to with the internals and the turbo because that's the place I haven't gone.
The only things I still have on my 'one day list' are the 1.6l stroker kit:
Stroker Kit 1.4 TSI
and the LOBA 270 Hybrid:
LO270P 1.4 TSI Upgrade Sport Turbocharger - JBS

Of course then I'd also need a custom tune.
There's something to be said for pushing something to the limits of where it can go.

But... by this point I may as well have bought an RS3
