Default [Q] Push email for gmail account for default email app

Hello All,

I just bought a Nexus 5 and got a upgrade of android 4.4.3 yesterday.
Well, Is there any way to have push email service for the default email app for a gmail account.
Android 4.4.2 had a bug with exchange server and it has been fixed. I checked it on my hotmail account. I am getting notifications without turning on the sync. Same what I want it for gmail account.
I know I can use the gmail app, but for that sync should be turned on and I guess it will consume more battery.

Gmail sync is possible on my previous phone that was Galaxy R which had samsung push service running in the background.

Is there any way to achieve this in Nexus 5?
