I know I sould be asking this in supraforums but for some reason i can't post there. Anyway, when I rev my engine to about 4,000 RPMs in my supra and change gear it starts to sound like its going to explode. the highest i have changed is about 5,000 RPMs and i thought i had stuffed my engine due to the sound it was making. On the supra foums someone said something about clearance or something but I lost that thread. Does anyone have any idea why my engine makes such a bad sound at these revs?

just bought the car last week. the car sounds perfectly fine when changing gears at around 3500RPMs but as soon as it hits 4000-4500RPMs theres an extremely loud, what seem like, knocking noise coming from the engine. its not engine pinging because this is extremely loud. you can hear it from far away. the car feels a lot smoother when changing at 3500RPM aswell

the sound only occurs when reving from 4000RPMs and upwards so it only for a period of time less than a second when changing gears this high

sounds like a bottom end bearing - bad news. bad bad news
be wary of revving it that high, and watch to see if it starts creeeping down in the rev range. you could be up for an engine rebuild.
thats worst case
could be your crank pulley is loose
or something in the timing assembly

M-engines are known for bearing problems. Part of this is due to the design, but mostly it's due to mistreatment and/or old age.
Normally it is represented by a rhythmic sound. Get a screwriver and, while the car is running, touch it to the block in a few different places. Listen to the end of the driver and you'll be able to hear where the noise is loudest. if it's definitely coming from the bottom end, she's shagged!
