Don't take it as gospel, but you should expect 100K for a turbo and 200K for an NA before rebuild. My NA made 210 before the #6 cylinder got down to 100PSI, and although the others were still "within specs" at 150 (156 is Toyota's figure) I decided to rebuild the car I have owned since I bought it new 15 years ago. I could have done the valves alone and gone at least another 50K.
FYI, the turbo puts out lots more HP and torque, by using the exhaust gas to drive a compressor to push more air into the cylinders, and raise compression. It's pretty simple: Engine_Life = Running_Time/HP. Most turbo owners bump up the HP from stock, hence my 100K estimate. If you left it stock, you should be able to get 130K.
