The issue with shoehorning such a big motor into a small and narrow car is that even with halfshafts - the swing angle of the axles gets out of range even with small movements - causing undue stress on the joints. I have seen some frankenstien projects like this but they usually make an engine cradle first, with wide stance using long axles - then kind of install the cradle to the car.
Im also seeing that you hanged the transmission mount on the factory timing mount, Ideally you should have made brackets that would bolt doughnut round mounts into the metal work along with a couple of adjustable dog bones in the middle to control the engine's rotational torque. (like the old F20A engine accord had at front) - the reason Im saying this is because the sheetmetal in this car is light and your engine is already hanging in front like an Audi - it would torque off the factory welds - If you look at how the GTi is braced at the chassis legs to firewall welds - you'll know what Im saying.
Props to you for this, but this has been done to death on the G100 daihatsus in Pakistan, a far cooler project would be to cut out the rear, and make a subframe and engine cradle to make a midship khyber. (H) - with a wide stance.
