reliability impact of VVT-I in 05' v8 vs. current v8

actually the brake lights work fine for some reason. I got new bulbs and used one of those screwdriver things i got at home depot to check if there was still current in the fuses and the bulb receptors in the back.
but yah, if my brake lights didn't work, i would for sure pay to get it fixed at the honda dealer. wouldnt' want to get rear ended and sued for a million dollars.

i was browsing the toyota pressroom and it says that the pre-lim estimated EPA mpg on the 05 4runner is still 19 hwy on the V8. This is the same mpg on the 04.

i would assume that the pre-lim EPA mpg would be an optomistic view, therefore, i guess that the extra 35 horses negates the VVT-I in terms of mpg? I was kinda using more mpg as a bargaining chip for me to wait and purchase an 05. I kinda doubt i need the extra horses, though, i dont want to regret not buying the "best".

VVT-i should technically improve gas milage by improving the power available at lower RPM... thus causing the motor to not have to rev as high to achieve 'X' rate of 'easy' acceleration.
However, the i-Force motor already had a torque biased cam profile as was, thus VVT-i really only helped the high RPM horsepower specs and made little to no difference with low end torque.
It still should have made a very slight difference, but we're talking well under a MPG, and that might have been offset by the now slightly increased compression ratio (I think the new motor is 10.0 instead of 9.6 unless I'm remebering wrong?)
If you have a heavy foot, then VVT-i should help to improve milage noticably, but the EPA does not test under those conditions.

It may, as the Celica's 2ZZGE which has VVTI-L requires premium. I doubt it though since the 4Runner's V8 VVTI engine won't be as high strung as the 2ZZGE but figured I'd put both sides out there.
