Which rotary is my best choice
 

I'm finally giving up on my Opel motors and am going to transplant a Rotary into my 1970 Opel GT body.

I want it to be easy, but I also want the best perfomance the first time out.

I may have to steer clear of the turbo as my passenger side engine bay is quiet tight, so which stock rotary setup is my best starting point to begin with.

This will also be a daily driver so reliabilty will be key, and I'm in texas so the one that adapts to cooling the best in traffice with A/C is also a consideration.

I've looked at teh 12a's and the motor mounts look like the easiest to work with, and I've owned 88's and 89's non turbo's and I'm comfortable with the FI quirks, so tell me in your opinions, Torque and driveablity which are my best options.
