Salaam - I can PM you details of someone who can get you all the parts you may be requiring and if I may share my experience with you. I had a corolla which in total costed me around 1.1 million - I changed it inside out. It will be fruitful in the sense that you will enjoy the ride more but as far as the market of the car is concerned unfortunately, the mindset people have here that it is not original, blah blah blah! Sort of damages the market of the car, it will be hard to sell it or may take a lot of time.
I would suggest, you should sell this one and look for a JDM Diesel Variant of this Corolla, which will have 85% of the parts you mentioned in it already.
Below are a few pictures of my corolla for reference.
