Help! 2.5L 2012 Mazda3 / 2011 Fusion Engine Swap

[Joser3001]

Hello, greetings to the whole forum. I am making an engine change of my Mazda 3 2.5l 2012 for the engine of a Fusion 2011, but I have a problem installing the flywheel. At first we tried to install the one that came with the Fusion engine without success, the internal screws do not match approximately 1/4 inch, we tried with the original Mazda and we also found that it touches and feels somewhat tight to the point of not being able to turn the plate, has anyone made this change? Any advice or experience in this regard? It should be noted that it is an automatic transmission. Thank you

I'll assume you figured it out by now, but were you by chance putting it on backwards? Sometimes they're drilled in a pattern that only allows the bolts to line up exactly in one orientation only. Did you use Loc-Tite or some other thread locker? Did you replace the rear main seal?

Hello, thank you for your answer. It was installed in the correct orientation but no, they do not fit, and with the original Mazda flywheel the problem is that the original flex plate pulls the torque converter out when you bolt it on. On the loctite, no, it was not placed, and on the rear main seal, no, it was not replaced.
