Base will probally have the Civic SI motor and Type S will have the Type R motor.
It will most likely have SH-AWD. SH-AWD in a 300+ HP, 6MT compact car would be awesome....
I hope not. It would be a 'Porker' as draghon mentions.
Acura kind of crapped the bed with the TLX Type S. I suspect that the Type S will get the 2.0T but it will be the one in the TLX with around 270hp and optional auto.
The TLX was heavy because they wanted to give it RWD proportions, I don't think that will happen with the Integra since Civic based FWD is it's origin story. Also, the gain of a true torque vectoring AWD is more than worth the weight gain in an already compact car.
The Civic has been receiving very positive reviews and Honda/Acura chassis engineering has always been on point so imagine the performance variants. I'm excited for this Integra (and new CTR), something I haven't been able to say about attainable new cars in a long time.
