I eat about the same protein as you and am the same height, but my start and target weights are slightly lower (st: 160, target:132). I track my calories/macros religiously (my wife calls it an obsession that I weight and track all the food I eat)
I would still not advise you to go over 2 lbs a week of weight loss (which if you do everything right, will be about 80% fat, 10% muscle and 10% water, give or take). Just because you eat more protein (or lift weights) doesn't mean your body won't trigger muscle breakdown. It will mitigate the amount, sure, but won't just magically stop it because of high protein intake. What most likely will happen, is your body will use protein for energy.
It is quite hard (only found one study that corroborates this (and it was with really untrained obese males) where there was actual muscle increase while losing fat (something along the lines of 2 kgs muscle increase and 9 kg of body fat lost over a period of 6 months I think), but interestingly enough it was a medium carb, medium protein, low fat diet. I'll try to dig up the publication when I can.
Also, do note that keto/low carb (and do note, that fitness keto is different from actual ketogenic diet, the latter being more than 85% of calories from fat) diets tend to produce quick weight loss at the beginning due to water weight and I still recommend to regularly have an high carb-eat at maintenance day to restore hormone levels and fill up the muscles with glycogen (and this will make you go up the scale 2-3 pounds). (ps: high carb day = loads of fruit, some rice, bread, not icecream+cookies+chocolate)
I too have personally had the best luck with 1.5 lbs - 2 lbs per week. The proper caloric deficit to achieve those weight loss amounts per week, along with a 25% carbohydrate, 47% protein, and 28% fat diet has allowed me to lose mostly fat with very little muscle.
With my body at least, it seems that the difference between 2 lbs per week and 3-4 lbs per week is huge in terms of how much muscle is kept during the fat loss process.
If you're already hugely overweight than of course it doesn't matter and fast weight loss should be expected.
