Hello everyone, it has been awhile that I post my last post. My 2009 Pontiac Vibe GT needs a new engine 2AZFE. Can I use the 2AZXFE engine from 2008 Toyota Camry Hybrid? Thanks,
Glen
2AZ-FXE
The 2AZ-FXE is an Atkinson cycle variant of the 2AZ-FE. It has the same bore and stroke, but the intake cam and pistons are unique. It has a physical compression ratio of 12.5:1.
The large valve overlap leads to a reduction in cylinder charge and reduced torque and power output, but efficiency is increased. This combination makes the 2AZ-FXE suitable for use only in hybrid vehicles, where peak torque and power demands can be met by the electric motor and battery.
Excellent Wikipedia article. It even goes into the "oil burning" issue which many of us have! Also at 12.5:1 compression ratio one would think PREMIUM fuel would be mandatory? Maybe it is on those models. Don't own one so I wouldn't know.

Atkinson engines are weird. Somehow they pull it off with only 87 Octane.tpollauf wrote: ↑Mon Aug 09, 2021 12:59 pmExcellent Wikipedia article.
