I want to know if the 1500 vezel engine or the 1800 HRV engine would bolt up to the hybrid system in my 2013 Honda fit shuttle hybrid. I love the look of the car, but the lack of power is painful.
I know I can swap out the drum brakes for disc and even convert the hubs to 5 stud with no fabrication needed. I'm hopeful that Honda's known compatibility would allow such a monstrosity.
My wife owns an HRV and the power it has is more than enough for me.
I guess i'm hoping they share the same block and possibly head which would make this viable and a fun project.

 

I’m not a tech person, but I’m not sure if this is possible. Would be nice to know if it could be done. There are many things about my Fit that I love, and many I hate, among them being the anemic power output.

My wife has a’19 HRV, and whenever I get the chance to drive it, it seems to accelerate much faster than my Fit, while still maintaining good gas mileage.

I’m sure more mechanical experts will chime in and I’d like to read what they have to say.

 

Looks like you got the LDA-MF6? The CR-Z got the 1.5 liter LEA1 hybrid drive train, which is the same technology generation as your Fit. If anything, I expect that would be your simplest swap. Later drive trains have more impressive specs, but you're going to run into issues like engine mounts not matching up, engine bay space limitations, battery compatibility issues (nominal voltage, current supply capabilities), and other electronics (ECU/BCM/gauge cluster) not wanting to play nice with each other.
