we're both wrong, actually...it's 283. I was wrong because I was looking too quickly, and I'm assuming you got the specs from autos.msn.com (which are frequently wrong on their specs). I remembered it being less than 300...and having more torque than hp is not too common for such relatively low displacement (3.0 L V6).
You're right, it is a bit heavy. In fact, it's about 300 lbs heavier than the NA version, the differences being turbos, intercoolers, HICAS (4 wheel steer), leather seats (driver's side is electric). After that, its just an all around heavy engine. People that are serious about making a Z fast usually start with an NA (I didn't know this), and convert it. The HICAS doesn't do that much, I'll probably have it removed when it breaks (plus get lighter wheels, and race seats). If one gets crazy with their weight reduction, one can drop over 700 lbs from a TT. But you have no interior left at that point...and who would want to do that to such a beautiful car.
Yeah well...I average more than twice your MPG...and including stereo/maintenance/performance parts, it has cost me about 20k, so hah. 
Really looking forward to it now, I just hope there's no rain, and the sun shines that day (nobody likes a cold track).

I believe in the theory of intellectual osmosis, so if I abruptly leave our conversation, you'll know why. Have a Nice Day.
