Most Soarer clips have an automatic trans. Most importers play dumb and sell people Soarer clips when they know it's for a Supra, which is why good deals don't always turn out to be good deals. Like annoyingrob mentioned, you could buy the Soarer trans and swap it for a Supra trans and make a few bucks, if you can find a Supra r154 and a Soarer/mk4 guy that needs a trans.
You can get a Supra mk3 trans converted to the lengthend shifter soarer/mk4 style for $250 now, so it's not necessarially going to be worth that much more. One of my importers is in Japan right now, and he's looking for Supra 1jz clips and not seeing anything available at all. I just talked to him yesterday. I do have a 1jz clip available now, and it's a SUPRA JZA70 5SPEED CLIP, not a soarer or a chaser. With a clip you also get a hydrofan, intercooler setup, a harness that is easy to wire into the mk3, ignitor, map sensor, the correct trans for your mk3, ps reservoir for mk3, ps cooler, etc....
