Yes I know civic turbo is trigger after 3.xK RPM. Yes I believe you can drive without turbo if you keep the RPM below the treshold. (I'm not turbo expert).
You testing me or really newbie ?

Hehehe. No harm in asking and learning. Mana tau I may be wrong.
My understanding of turbo is it's always working from the moment you start the engine. The higher your rpm the faster it spins and the more boost you get. Ours starts boosting at around 1.5k rpm.
Just to add, turbo engines usually have lower compression when compared to NA. This is to allows more air-fuel mix to be pumped into the cylinder. Because of this, when you do encounter turbo failure, your engine will shudder a lot and feel lifeless. In essence, without the turbocharger, it's actually a lot less powerful than a conventional 1.5 NA engine.
As for 0-20 oil, I believe it's sufficient for our engine. There's a lot of false information being spread about the maintenance of these engines. Unless you're pushing it really hard everyday, upgrading the oil is just overkill.
Just my 2 cents. Kalau salah tolong tunjukkan.
