(if you haven't already got it in your favourites, PUT IT THERE!!! It's a godsend!)

In the tsrm it says if the wastegate itself is stuck, buy a new turbo!

OK, back to planet earth & most stuck 'gates can be freed by oiling the pivot & working back & forth with pliers (actuator disconnected at this stage) until it's nice & easy to move again.

A lot of turbos can be got to without removal but the CT26 is a bitch to get at in the Supra (ask my knuckles!) so you'd be best off removing it if that's the issue. As cre said, if the 'gate is siezed the actuator may have been damaged by now but considering the price of new ones it's worth testing while disconnected to make sure. Not with "a ton of pressure" though as this can damage it, just around 10/11psi as in my previous post & it should move at around 7...
