Looking For around 162 MHS ethhash.

I will never say it's a scam you can ask the partners later after a month of success. If i answer your last question it will not make any sense.
Anywayz all the questions you asked are already answered in last 2 posts but i have written short answer to each in the comment.

Sorry. Thanks though. Nanopool doesn't have a mining calculator, but MinerGate.com estimates that that sort of hashpower would be $249 a week. Am I correct in thinking that?

I use cryptocompare.com because it give more accurate reading for current difficulty rate. And we will get almost 700$ a month. But electricity cost will be deducted from this.
The current profitablilty can be calculated but project profitablity can never be calculated so it's just a number to make plan.

Is this still open for investment?

Nope. As per final announcement it's closed
