What damage is said the engine has that it needs a new engine? Valves hit the pistons?
Have someone stick a boroscope in the cylinders to look for any signs of piston-valve contact. Have them verify the timing is correct, do a compression test and leakdown test and check the fuel pressure.
As said before: the mechanic at the 1st shop messed up, doesn't know where to look for and starts trowing random new parts at it... proper diagnosing is key here.
Prepare to go to court (or at least have a lawyer on standby....)
