Car currenrtly has a 2.7 engine and runs 914-6 brakes in back and SC up front.

How do I get a better brake feel? How do I add more stopping power, and is that necessary as I potentially upgrade the engine?

Has plenty of rubber.

As stated, the need for braking power is mostly down to car weight and available traction. If you can lock your current tires, you have enough brake power. Any more brake power, and you're simply overwhelming your tires sooner, which does nothing for stopping ability. If you can lock them repeatedly, you have enough heat capacity to avoid fade. If you find you have to press harder and harder as you repeated come to a stop from high speeds, then you need to look into better fluid, better pads, and maybe better rotors.

You asked specifically about brake feel. If the pedal doesn't feel right to you, then it's possible you have to deal with hydraulic compatibility. If the pedal is uncomfortably "long" and/or feels squishy, then you may have a master cylinder that's too small for the calipers you're using. If the pedal is wooden and hard, then you may have a master cylinder that's too large for the calipers you're using. There's a post I made awhile back on the subject you can search for.

If you can't lock your tires no matter how hard you press the pedal, then I'd start with brake pads (find softer compound pads), and make sure the current pads aren't glazed or contaminated.
