Here my take:
You have to walk from arriving gate to immigration - about 15 minutes
Then pass thru immigration that can be 15 minutes( my experience later in the day, the longer the wait).
Get your luggage usually -wait 15 minutes.
Go thru customs- just smile- 0 minutes
Go terminal 1 -15 minutes
Get luggage checked in- 15 minutes .
Pass thru security-15 minutes
Run to your gate 10 minutes
That about 100 minutes. Your plane maybe a little early and you can make it, but if you do -it will be close. Planes are generally early when they arrive in the afternoon and later at night.You may cut a few minutes on each hurdle, but some could take you a bit longer too!
