I have a 1991 dodge daytona and It's teasing me bad. From the time I got the car, When you stomp on it, it go's into overboost and kills the ignition (From my understanding) So a few weeks ago while doing a oil change my father was messing with the vac line's trying to make it get up to 10 lbs and hold it there. Rather then putting a stop to overboost He alloud it to do w/e it wanted. So the boost spiked to about 25. The car snap crackled and popped. He barely made it home with out stalling it. Exhaust was pouring out and the motor was knocking. We took off a few parts and got our fingers in the turbo and it wouldnt spin. So we thought it was dead. I drove the car, it smoked and still knocked --when I say knocked It's almost like pistin slap It's not too loud-- anyway the car drives but with no turbo. Then after sitting for a while (about a week) I drive it, I SLOWLY get up to around 40mh and BOOM tap tap tap The turbo spools up!!!! WTF!!! I cant think of ANY reason for this to happen??? can you???? The motor still has the knocking quietly but at this point I have not a clue of what to do.. Tear it down?? Drive it?? What??
 
If you really ran 25 lbs of boost through a stock engine, it's done. Just get rid of that car because you won't get any money you put into it from this point on back out of it. Even 10 lbs of boost on a stock engine is a bad idea, especially a 90's Chrysler engine... yikes
 
I sure wouldn't be driving it that way. I don't think the knocking is the turbo, if they stop working you just don't have much power. That's what happened to mine. Sounds more like engine troubles
