The engine is likely very similar but the injection is different on later EA888 engines. I’ve no idea about gen 4 camshafts unfortunately, but most things like that are more emissions related than anything else these days.
What you won’t get with a turbo engine is a VTEC kick! Well, you will get a kick when the turbo starts spooling at 2000 ish RPM that you can manipulate on part throttle to get a catapult effect, but from there on in it’s a progressive gain due to the turbo being a pump that basically just increases in speed until it hits a ceiling.
Twin turbo units can obviously be tuned to give a VTEC type boost at higher RPM’s if using different sized compressors.
