UniBody vs. Horse Power

It's not a matter of how much HP but how long will it take with the HP you have and how hard you drive it, even with mildly modified engines. Eventually, problems like cracked paint on body seams, mis-aligned doors and alignment problems will surface if driven hard.

The first step is to install frame connectors. Welding to the floor in spots along the way or actually having them pass through the low portions of the floor and welding it all the way.

The next step would be a 6-point roll bar. Adding 2 more points, just behind the passenger and driver's seats from the side of the main hoop to the frame connector will help even more.
