Well, you aren't gaining anything by making the car run colder when it is under light load.
If you put in a 180 you will probably find the car runs considerable colder when puttering around. You will also find that the heater and defroster aren't effective until a longer period of time elapses first thing in the moring - which gets old quick.
However you will also probably find that when you run under heavy load that the temp comes almost back up to where it would be with a 198 (stock / 92C) by the time you have run through a couple gears.
I logged it with OEM and then a 180 within the last year or so... it's over on FJ FI.
I really can't imagine that a 170 could provide any advantage at all over the 180.
