proper tuning = drivability . Yes the RB will provide more torque due to it being an I-6 over the 4. But the SR will give the car a better balance over all due to it being lighter than the RB and a little lighter than the KA. As long as you get the correct turbo setup for the SR you shouldn't sacrifice any daily or track driving.
