Very strange question, I know that but I just need to know if a gen 2 engine (12-14) can fit into a gen 3 frame (15-current).
I would have thought that there would be some differences?
If the mountings are unchanged,which,as far as I am aware,the casings are the same.The main modifications were inside the cylinder head.
You would need to use a gen2 exhaust though as the exhaust ports are different.The bigger problems would more likely be ecu electronics.
