Aoa,
I own Toyota Vitz 2013. Its been almost 10 years since I am driving this car. Car is mechanically and electrically perfect and driving is as pleasant as it was on day 1. Now I just want to get the feel of a bigger engine and mileage. I don't really want to change the car sine it is in an excellent condition. I have heard I can install bigger engine 1300cc/1500cc for better mileage and low cabin noise - those two are the only nuances with this car. My current location is Lahore and I want to know if there is a possibility to procure a bigger engine and get it installed? I know 1000cc engines are easily available but I am not looking for that. Anyone who has personally done that or know things around please advise.
Thank You and JazakAllah khair!
