out on a limb here about new model

Theres no way a tt v6 weighs more than a v8. all your adding is turbos, charge piping and an intercooler along with misc. fittings etc. Can't count the weight of the manifolds, because they are there whether its n/a or not.

OEM setups can weight a good bit because of standards and environment items they must follow. Also, cost becomes a factor so adding a bit of weight to save X amount plays a big roll.

Look at the LS7 and the GT-R's engine/setup. The GTR's powerplant is WAY! heavier than the LS7...and still makes less power.

GT-R Engine: 608#

Lol, the engine AND transmission weigh almost 50# LESS! than just the turbo V6 in the GT-R with it's piping and turbo's...and it makes more power.

Yes...a V8 is the way to go. Once you get over your warm and fuzzies about all that technology and all those moving parts, an "old school" pushrod V8 is lighter and more powerful and just plain makes more sense.
