- CX5
I'm toying with the idea of transplanting a turbo gas 2.5 CX-9 engine on a CX-5. AFAIK they are the same except for the turbo charger.
Any thoughts?

Wow. So many things to consider. I agree with you guys that "turbo-ing" the current engine is a better option. But aren't turbo engines different in built although the same dimensions? An example is the pistons. My friends changed their pistons whenever they add turbo to their car.
Just toying with the idea and at the same time trying to stir up the minds of Mazda owners. Hehe!Yes. You need lower compression pistons. Turbos run on low compression. is this turbo build something you are actually considering doing? You should be able to get it all done for roughly $5000 USD or so. Another option is a supercharger, which will result in a more linear power delivery and better power in the high end. The turbocharger will not affect fuel economy though.

Yeah lower compression. Plus I think the connecting rods would probably needs replacement as well.
I think it's impossible to turbocharge the CX-5 given the limited engine bay area.
You don't need low comp pistons. You just run a lower boost pressure. There are a few 2.0L skyactives on stock internals already. 8psi has shown to be safe and bumps about 100hp. And that's with less than perfect tuning because the mitsubishi ECUs on all first gen skyactives, and some up until the 2016 my's are missing tables for boost tuning.

This is correct. Dave Coleman has said that the only car it doesn't fit in is the CX-3 (which probably also means it doesn't fit in a Mazda2).Mazda has already said that the Turbo engine from the CX-9 will fit in the CX-5.
Is it possible to lower the boost pressure without affecting the stock "Atkinson cycle" timing of the valves?You don't need low comp pistons. You just run a lower boost pressure.

I've heard that line before.Sell the CX5 and buy what you really wanted.
I've heard that line before.

And even after you get what you want, you'd still go on with toying with it again.
That is what my friend told my colleagues so he bought a Subaru STi. After a year he ended up spending $18k on upgrades. [emoji28]
