Anyone know where i might find parts to rebuild/recondition my (DY) Mazda 2 ZY-VE engine? What parts are compatable from the other ZY-VE engines (DE/Demio sport DE)

I am able to find pistons online for the DE but nothing else. My main issue is finding rod bearings and possibly piston rings, no one seems to offer them anywhere.

I also looked around and got quoted $3400 for a Bare Long Block but i have to send them my entire engine that for the time still runs fine.. so im essentially trading a full running engine for something thats only 1/3 built for 3.4k...

Can anyone help me out on this. Most people would say just shove a bigger engine in but i enjoy the fuel efficiency to power output, i will mod it later once i get it rebuilt but it won't be a turbo as id rather a super charger, that of which will be done after 10 years of ownership. Hopefully the chassis take me there
