I'm strongly considering an LS2 C6 (A4) as my next half year dd/toy.

I have a question as far as mods go.

What's a realistic amount of power a completely stock bottom end LS2 can handle on 93 octane, going the boost route???

Stock block, stock internals. Breathing mods and boost cam and heads done before hand

Has the 6L80 shown itself to handle that amount of power???

I won't be taking it to the strip (not more then a couple times). I want it mostly for personal enjoyment and 'not so cheap' thrills. It might end up with light road course (watkins glen) duty... No track whoring though.

Thanks for any info.
Actual examples would be great/ mostly what I'm looking for.

If your going for the A4 it's a 2005 model and whatever a 4l60e can handle. I've seen a c6 that made roughly 550 with a magnuson blower.

Hey man, the A6 tune (TCM) will have a lot to do with the longevity of the trans. They have been up to 550rwhp with no issues yet but then again, they have let go near stock, its mostly in the tune. I have 450ish-rwhp and it never misses a beat. I would grab an 06/A6 and since it is an auto, you don't need a Z51. Tune the trans, custom Vengeance/LG cam and ported heads/FAST and you will be right @ 470-490rwhp.

Then add a 150 shot if needed.

That's actually what I'm thinking about doing now anyway.
I don't think I'm goign to bother with a Z51 package, if anything I wouldn't mind going with coilovers.
The C6 A6 is a strong contender for my next purchase list, I can't think of anything that can beat it for it's price in nearly anything.
Now I just need to find a nice clean one locally, that HAS GPS etc...
