1zr fe is best would be in price range as alone good condition just CVT transmission from 2zr fe is no less than 150,000 rupees.
Now come to 1zr fe so average and performance wise 1zr fe is best compare to most of 1.5 or 1.6L cars. I took my cousin’s altis 1.6(1zr fe) to inter city travel and it gave me easily 16+km/l average with utilisation of power on passing other cars. Car was full of luggage in trunk and 5 people were sitting including driver and AC was on full blast all time.
And if you have real budget issues the 1nz is also good engine and performance would be on depend on luck to find a good one. And also have no idea about the latest rates of these engines.
Last time may be month age hot quote of 155,000 for 1nz complete engine with CVT transmission it was just quote on phone didn’t saw engine in person.
1zr is bolt on fit in 2010 model as facelift model 2011 come with same 1zr fe engine in altis and gli 1.6 automatic.
