Just wondering, what would be the advantages/disadvantages of running a 160 degree thermostat compared to a 180 or 195 degree thermostat in a 280zx? Any comments would be appreciated.

engine will run cooler, but it'll put a bit more stress on your water pump i'd think... 170 is as low as i'd go.

yah i definantely wouldnt run 160 thats too low plus engine will run crappier i woulnt go lower that 180 but thats me...
