You are right, I am reading "torsion bars alone" as "TB suspension system alone".
If you are willing to go aftermarket then you should be thinking of both as a system.
Here's my list of aftermarket or upgraded parts:
.99 torsion bars
1.25" sway bar
RCD shocks
9/16" aluminum tie rod sleeves
Offset upper control arm bushings
Lower control arm stiffener plates
Borgeson PS steering box
The full monty list is in the linked thread or can be found in other threads so I'm not going to go into costs or what parts.
I will add that if you were to just upgrade your TB's and not do shocks, you would end up with an inferior system. The bigger bars need a quality shock to control them or you will end up with a rough riding car.
