Reviving this thread. Any updates?

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.

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

8*1000cc injectors is to small for you with E85, you will need bigger!
I have bought 1500cc now for my car, because I was already up to 84% open time (and it was with less power than you have had.) on mine EV14 1000cc which I have been using now for several years on E85.
I have dual walbro 450 in a fuel surge tank standing in the trunk.

With a modern injector like EV14, you can drive with over 2000cc each without problems, (But I could not find any larger EV14 that have the same length etc. as the ones I used, so therefore I bought these 1500cc now.)
But you may have problems getting the right values when you use air mass meters? But for me with MaxxEcu I can use whatever I want.
I also drive at 3 bar
I don't know how much better an Walbro 460 flows than 450?
But if you have 3bar + 2bar boost = 5bar = then one 450 can deliver fuel for maximum 640hp with E85
But if you have 4bar + 2bar boost = 6bar = then one 450 can then only deliver fuel for maximum 550hp with E85 so 2 pumps will only flow for maximum 1100 engine hp.

Yes, but also bigger injectors.
If I use a injector calulator and type in 8 pcs and 1000hp in a turbo engine and 85% duty cycle.
For gasoline = 950cc
For E85 = 1235-1300cc
Bosch
EV14 1000cc = 3bar/950cc, 4bar/1080cc, 5bar/1212cc
EV14 1200cc = 3bar/1095cc, 4bar/1275cc
EV14 1300cc = 3bar/1245cc, 4bar/1435cc, 5bar/1615cc
EV14 1500cc = 3bar/1450cc, 4bar/1690cc, 5bar/1900cc
So if you want 1100hp then you need about 1400cc and for 1200hp over 1500cc injectors.
So you need at least EV14 1300cc injectors and drive them at 4-5bar
EV14 1000cc is part no 0280158040 = what I have used, is it the same that you have now?
EV14 1500cc is 0280158333
