No i sent the piston to JE and they kept it. I was just reading about the failures in cylinders #4 due to the oil jets not being sufficient. My car is a 2001 and i have the old jets.. can this be the problem........Let me tell you how the car gave out in the highway.. I did a run from 65mph to 120 mph it lasted for about 2 miles then i slowed down back to 65 and drove for another 1 mile then i got off the highway. i was at a red light waiting to turn green the all of a sudden the car stalled and it smoked out the back. i got it to start and i drove it home wich was 3 miles away. ..What do you guys think could it be the oil jets...

Possibly. You really should've upgraded to the 4-hole jets when you slapped on that turbo.
It sounds like you possibly could've starved that cylinder, had too much oil pressure and focked up the rings... They seized, your pistons slapped, and you crushed the ring grooves. This is all from running that motor WOT.
Then, when you started slowing down, it wasn't enough to stall your engine at 65mph, but at the traffic light, at idle, it was enough to kill it. But, it wasn't enough to cause a no-start.
Iunno.

YES.
If your ring grooves have collapsed, replace the pistons. But make sure you check EVERYTHING is with spec (conrods, crank, cylinder bore, etc.) before putting it all back together.

Its kind of hard to believe that MS did not use a 4 hole jet piston when he built your motor. I say this only because the 2 hole jet is a known problem and has been dicussed throu out this forum extensively. Maybe this is something that Chris can confirm....

Wait, is your motor the MS motor? I thought you had the $6k engine swap. If not, all I can say is good luck. 
There are a few options on the first page of this thread.
