How to limit current for a transformer?
the frequency is 60hz

and

I'm supplying 80v to the primary

and

160 turns on the primary side

To avoid excess current into your primary you probably need more turns. A typical medium size standard mains transformer used in old fashioned household goods might have enough magnetic permeability to produce 10 μH for one turn and, given that inductance is proportional to the square of the turns, 160 turns will produce about 256 mH of magnetization inductance.
At 60 Hz, that's an impedance of about 96.5 Ω and, from an 80 volt supply, the magnetization current will be about 829 mA RMS. The primary RMS ampere-turns will be about 133 (take note)
That might be too much current and cause core saturation problems (to be avoided).
A pretty standard middle of the road 230 volts mains transformer might have a magnetization inductance of about 10 henries and it would have about 1000 turns on the primary. The current from 230 volts would be about 60 mA and so it would have a magnetic field strength of 1000 x 60 mA = 60 ampere-turns RMS.
So, your transformer (all other things being equal) looks to have over twice the ampere turns and might saturate. You definitely need to do some math on this.
