Christ is quite knowledgable about turbos but no one has touched on the basic problem: that is, any dealer-equipped model has too large a turbo for mpg applications.
I have over 2 million miles on properly-sized turbocharged engines. What are they on? Big trucks.
But those turbochargers are huge, you say.
No, they're not.
If you look at it in terms of power to weight, they are very small.
This is the Ecomodder Forum. Let's talk about ecomodding.
Any turbocharged engine has forged pistons and lower compression, if it has been properly assembled. All that is needed is to install a much smaller turbocharger with a properly adjusted waste gate and fuel delivery for excellent mpg gains. Your top end horsepower will fall off significantly but your midrange torque will delight you.
