drain your tranny fluid and check for bits of metal. sounds like you could have issues with the M/T that you installed. was it used? how many miles were on it? did you change your clutch, pilot bushing or anything else that should be done when you have the trans off?

the input shaft bearings are very easy to damage in the sr/ka trannys. if the trans is hung wrong or hangs on the input shaft for ANY amount of time it can smoke the bearing. hope this helps you out.

Before taking anything apart, jack the rear end, CHOCK the front wheels, and slowly let it roll in the air, going through each gear. See if you hear the noise then, and if you can hear it with the engine letting the car roll in gear without stalling. Then get under it and track the noise down. If it goes away with it in the air, it's only under load, so start pushing on loose items near the driveshaft and see if it changes.
