All the parts will fit, but you may need to get other parts to make them work.
For the engine/trans, you'll want the engine, trans, axles, wiring harness, ECU.
For the suspension, you'll want to get the springs and the sway bars, as well as new struts.
For the HUD, you'll want the dash, dash wiring harness, dash trim and HUD switch. When doing all that, you'll probably want/have to upgrade to the Electronic climate control, which means a new blower motor, ducting and climate control head.
Basically, to swap all those over correctly, you'll be better off buying an SSEi to begin with.
If you still want to do it because you like your car, then we can help there, but just know it might get expensive. If you don't mind if it is not factory looking, you can skip some parts, but it'll still cost some money.
