speaking of shotpeening NOW true 2 litre
I am building something very similar (83mm Mahle pistons * 92.8). I have
pretty much all my parts, including ARP hardware.
I am only missing a Schrick camshaft, and a lightened flywhell, and then
will get it balanced. I just got my Audi hydro head p&p (by me) from the
machine shop (valves/guides/3 angle job).
The sad news is winter is just around the block, so the motor will not go
into the car (along with a shortened ratio rack & pinion) until april...
Cheers.

Sounds like a nice recipe for a strong N/A engine! With a 92.8 mm crank
and 83 mm pistons, you have a true 2 litre (2008)! With the 10.5:1
compression it's not setup for a turbo/supercharger though...
You might want to install a knock sensing ignition with the higher
compression. If you don't feel like doing that, run the highest octane
you can, and keep the ignition timing conservative (around 6 deg btdc).
Nice score Dan!
Mark.
