After failing to get the desired offer for my Indus Corolla through Pakwheels and OLX, I decided to give it some love and keep it instead. There couldn't be any better way of starting the restoration with an engine swap. So I got the stock 2E replaced with a 5AFE in good condition with complete wiring and stuff. I would like to express my sincere gratitude to @saadeez101 for his advice on the swap. I would also like to thank the other Pakwheelers who had posted similar threads about engine swaps, which helped me learn about the process and inspired me to share my experience as well.
I got the swap done at Ahaata Mitthoo Khan in Rawalpindi. Some other things were also fixed in the car that I'll share with pics.
