Performance upgrade/safety

I am restoring a 1970 911T - full ground up and planning to replace (but keep) original engine with a 2.7 that produces considerably more power. I have a 915 gearbox and 911SC brakes from a donor '78. The tub is sound from complete dismantling/rebuilding. I would like to keep the original appearance, but enjoy the added performance. Is there any further safety, handling, or stopping consideration I should make at this point of the project?

Sounds like a fun project! A few thoughts:

Definitely new DOT approved brake lines as old ones go soft and then brittle.

Koni or Bilstein shocks and front/rear stabilizer bars. Maybe stiffer torsion bars.

Probably a bit more rubber than the 185/70s that Ts came with. I got 215/60s and 7" R rears wheels on my old 70 911. Stock tires are hard to come by with lower profiles today.

Consider a roll cage if that is an option under "original appearance." Obvious roll over protection, and it can stiffen the chassis significantly. Especially if track days are planned.
