Mazda CX-7 has two versions: a 2.5L naturally aspirated engine and a 2.3T turbocharged one. I'm currently driving the 2.5 version and want to add a turbo. Is it possible to convert it since there is a turbo version available? Does it have more tuning potential compared to other Mazda models? Looking for advice from experts.

Anyone using USB to watch videos? Also, for those who have updated their system, is your data enough?

As a new driver, I've only driven the 2019 2.0 model, and I find the acceleration quite sluggish. When I press the gas pedal deeply, the engine needs to reach around 1800-2000 RPM to speed up a bit, and the engine noise is quite loud. Is this normal for a naturally aspirated engine with a CVT? I tried using the DS mode, which seems to provide what I consider normal acceleration, but I noticed the RPM goes up to four or five thousand. My friend's 1.5T Geely doesn't make much noise and feels more powerful.
