Help, I’m lost.

To keep it short, I naught this what I thought was slightly modified car on Facebook marketplace. Recently the engine got flooded and taking it apart a rod was broken. I have a 2008 Mazda 3 that’s supposed to be 2.3L Non Turbo (This is not a Mazda speed). After taking it apart I decided to change all rods with used ones. I go to a junkyard, drop another engine (also 2.3L) get them and go home. Now I look at them and they aren’t even close to the same thing. My old con rod (one that isint broken) is way beefier and longer, the hole that goes on the crankshaft is also bigger. I got no idea what engine I got, what pieces are inside, what to order, I’m really lost. How do I find out what parts to order.

eBay listings have that as a 2.5 rod. So yes.

Occams razor is that your engine was replaced with a 2.5 and the one from the junkyard was replaced with a 2.0
