My up coming project is a KE55 Rolla with a 13B Rotary Turbo from the series 4 RX7 now been told this car will twist its chasisi but i seen an old school rolla with a 454 in it

A full cage will fix this problem with no trouble.

I wouldnt have thought a rotary would have had enough torque to twist a chassis?
And anyway, if it does, buy another, KE55's are what, $3.50?

It's a common misconception that rotaries don't make torque. They actually make plenty of torque, especially the turbo ones, and more especially the worked turbo ones; it's just that rotaries make their peak torque at fairly high rpm. As far as chassis twisting goes, it doesn't matter what rpm the torque kicks in, so a worked 13B turbo is going to stress the KE55 chassis well beyond its design parameters.
The full cage is a good idea (make sure it's a cross-braced one, not just a rollover protection cage) but that won't be enough. You'll also want to strengthen the rear of the car where the axle mounts to the chassis, and the front of the car as well; a strut brace triangulated to the firewall would be a good start.

Yeah sounds good makes more sense now. How much do roll cages roughly go for?
