What was the noise?

if it was a damn loud clacking that means your bearings are TOAST. If you use pounded bearings for long enough eventually the car will do the start and die routine (amid lots of noise)

thats really all I can think of... I dont think Auto KA24s make enough power to crack ring lands.
Loud Noises - prolly the bearings getting loose

Cruisin Around on if for a day - Beating the shit out of loose bearings

Firing up the car the next morning - no oil pressure on shitty bearings = spun bearing(s)

Lots of spun bearings - Firing Sputtering then dying.

If the "loud Noise" was clacking Id drain the oil and look for metal shavings (or chunks)... If you spun the bearings that horribly then you'll need a new motor.

there is a bushing for the drive shaft. look and see if its worn out. the bushing (looks like a doughnut) is between the first drive shaft and the second one.

when wormn out, it causes noice and vibration right under the center of the car.

might also wanna do the diagnostic on your auto tranny
(yes there is one) pretty complicated thought
if you want to know it just let me know at [email protected]
i have the schematics at home
messenger would be an asset too as it is real time

best of luck

Check engine/transmission mounts. They are garbage on every automobile released that sports a KA engine. Even old minivans with SOHC KAs most often have crapped out engine mounts.

Dying is common on 240s with IACV related problems. Check out www.240sx.org for more on the typical problems associated with 240sx's.
