i recently bought a 1992 supra turbo when i acelerate the turbo kicks in just fine but at about 4500all the way to red line my engine gives me a vibration and doesnt seem like its pulling any more than it does at 3500 no power loss but no power gain i assume it should continue to increase g forces let me know if you can help

It may be your center bearing. It is on the drive shaft.

Is your Supra a auto or a 5-speed?

i checked the carier bearing and did a full tune up i assume its a sensor of some sort that comes on at that rpm its a manual five speed

Motor mounts? If you rev it up to that rpm with the hood open you should see the engine jerk up if you have a bad one. That would throw your driveline alignment off quite a bit and could mess up the power.
