Have a 87 Supra turbo that i just aquired, Runs fine when not in boost or at least decent. Soon as you put your foot into it, it just drops off. no boost, stock guage does not register shit and black smoke comes from exhaust (whenever you give it more than 1/4 throttle) on top of that the temp of the exhaust comming out of the tail pipe could light a fuckin ciggerette! lol please help me out guys!!:confused::help:

thats a good 1, start with the plugs and coil packs if you have a meter the packs should be between 0.3 and 0.6 ohms. then fuel pump and regulator. if the pressure is not right you could be leaning out and that would go with the high exaust temps. after all that your o2 sensor will prob. be cloged by now.
