Reviving this thread. Any updates?
Ha ha you just read my mind....
Currently the engine is out and i'm building it up with Pauter rods, forged pistons, re-lapped bores, fully worked heads..... GTX3071 Gen II or G25-660 turbos, not sure which way yet...

How far were you able to push the stock block? hp/tq?
What were you running? psi boost, maf g/s, etc
Have you been running e85?
I am currently researching for my own build down the road: 6sp swap, have spare bcy motor that I need to decide what to do with
Edit: Think I found all the info after reading through your entire thread(35 pages lol) on the aussie audi forum: 470kW and 1200Nm @ 21psi on 98 oct

Milka, before you pulled the engine to build it, what oil were you running? I have a stock block with about 19psi, been running Redline 5w40.
I've always run Mobile 1 5-50, i like the zinc and slightly better protection.

Stock block can reliably take 25+ psi, if you're careful about EGTs & detonation.
That translates to ~1200nm with hybrids.
However, for any serious build you'd really want at least rods.
Yeah if everything works as i'm hoping this should be bullet proof...
testing a solution for ARP main studs and ARP Head studs. I can let you know if my plan works.....
From a torque point of view i think i was very close to the limit, those GTX30 turbos pull like absolutely crazy, feels like the tyres are tearing the road apart at full boost and no taper.

Still looking for a good easy solution for fuels pumps to handle E85 for 8*1000cc injectors before I go E85 everything else is ready. I had started on making a dual walbro 460 in tank setup but have not really progressed it due to kids and time

Yeah most of that is correct, I didn't want to up the boost past 21 without some strengthening. 21psi on GTX30s is very different to hybrid turbos. Planning to run around 30psi give or take
