I have a picture of it somewhere.

That just made me feel old, but at least I can sorta pinpoint when that car was around

The rest of the powertrain might require more beef with the V8, but the blower probably offsets the two extra cylinders pretty closely.

It would be nice if GM started their own direct fuel injection systems. I bring this up because the Audi/VW engines are or will be taking advantage of the higher compression tolerances their FSI engines allow, thus reducing turbo lag even more.

The STI's 2.5L turbo 4 has good low-midrange tq. It makes a nice peak of 300 lb/ft as well.
The drivetrain will be just fine with a v8. The rear end is from a near 4000 poud car (as well as the upgraded version for the CTS-v) And the trans is from a truck with at least a 5k tow rating. Im sure it can handle a LS2.

For manuals, I wouldn't trust anything but a T-56 behind an LSx, and since it's a 5-speed it isn't a T-56.

Re: V8 Solstice from GM
Expect 6 speeds behind GXP and Redline models ( I think I remember that right, I'm getting old 
) Let's see what the turbos are packing before we start the "there's gotta be a V8 in this car to be fast" talk. When the aftermarket catches up with the turbo ecotecs, there will be no issues with sky high power numbers.
A little tidbit...peak torque on the FI motors will be well under 2000rpms and flat as a tabletop. GM powertrain really outdid themselves in tuning on these beasts.

I have to think about this...
The way I got this figured, 400 ft-lbs is 400 ft-lbs. Now, that might be very wrong, so I shall put my dunce cap on and ponder...

Re: V8 Solstice from GM
Go sit in the corner young man......of course it is, but most driveline failures are during the initial hit....you know, trying to move 3***#'s from a dead stop is harder than pushing it faster after already moving.......come on now, I'm just playin' Mr. Optomistic.....
