Here's an idea I'd like explored a little... (more)
The 3.2 liter block in the TT with the DSG transmission. What do you think the chances are that the block will bolt up to our transmission and heads? I'm trying to think of a way to come up with a 3 liter motor from an existing audi block. If the heads and tranny will bolt up, I say sleeve it down to 3 liters, get the appropriate internals, huge hybrid turbos, and of course the proper t00ning. Do we think that would yeild some bigger HP numbers?

I have no idea. I was just posing the question to see...
what you guys think about something with great displacement while using a stock audi block. Aren't the piston walls fairly thin on the 2.7tt as they sit now?

either way doesn't matter to me. If it's traverse, it's a moot issue.
If it's longitudinal, we might have an avenue to go down for some bigger HP numbers. I did think the 3.2 was only in the TT though...
Keep the ideas flowin'!

The 3.2l is a VR6 cousin, 15deg V6 as apposed to ours at a 90deg V6.
Think our block is about as good as they get from the factory(RS4 seasoned excluded) with 6-bolt mains and all... see pic poster. It's pretty robust overall. Think the A4/A6 3l would be a better target if displacement is the goal, but I doubt that short block is as capable of taking the punishment vs ours.
I've thought about trying to do a single turbo conversion(again thought about, not actually wanted to pursue) ala the 2.5l Audi diesel that comes in these cars, exaust manis merge to a bridge and then into a single turbo over the tranny bell housing. Still limited on space/packaging but a different way to look at the problem...

No way it will work
for one thing the 3.2l motor in the TT is a VR6 motor, it's a 15 degree narrow angle, it only has 1 head actually. Another thing is that the motor is mounted transversly in the TT, so the transmission is different (that is why it has a haldex center diff). The new A4 and A6 is comming out with a 3.2L V6 motor that is totally different. Also, the B6 A4 comes with a 3.0 V6 motor, but none are turbo charged.

One of the issues that I want to guard against is the thin piston wall
I want to be able to run an a$$ load of boost and keep the audi motor together. Somewhere isn the 26-28 PSI range and do it reliably...yeah, I have audi and reliable in the same paragraph...I said it!
