Default Re: 4.0 V6 Due for a power increase?

[quote=Jason.MZW20;955075]As I've stated before, the 1GR will likely end up with the lower friction roller-rocker valvetrain of the newer GR engines. This will improve efficiency. It'll also receive dual VVT-i. Perhaps Toyota will also continue to tweak the piston ring lands, piston skirts, and actual piston ring tension to further reduce friction and increase efficiency. A very small increase in power will come from these modifications, while increasing MPG by 1-3 in the city, and 2-4 in the highway.

I would tend to agree with this statement, it's only a matter of time...I mean hey, look what they can get from the 3.5 with dual VVT-i (and the engines are very similar except for displacement), tons of horsepower, decent torque and amazing fuel economy...that's one reason I'm looking at a new Highlander or RAV4 for my next family vehicle (270hp sounds good to me, the 1GR-FE should easily come close to that with VVT-i)

Love my Tacoma, but with the changes for 2009 and the possibility of a power increase, I may be tempted to trade up.
