DO NOT do this. It will easily take a you 90 minutes one way via train. I kno from New Brunswick to Trenton it's 30 minutes and to Newark about 40= 70 min plus whatever time on the SEPTA and transferring at Trenton.
If you're opposed to Newark (and you have every right to be), take a look at Jersey City. It's affordable, up and coming, and 15 minutes to SHU. And 15 minutes to NYC.
