Re: torsion bars?
ALL 2WD S-10s have coil spring, short/long arm front suspension. This can be a good thing, though as a few aftermarket suspension companies offer lift kits from mild to EXTREME! Though its not an IDEAL design for Off-road, an SLA suspension can be made better fairly easily. There's the Bullseye spindles that move the hub down, longer coil springs, spacers, longer tubular control arms, etc. It all depends on what you want to do. Good luck with it.
