The 4000 rpm cut out is a defective overboost limit switch located right on
top of the intake manafold near the letter "o" in the word "turbo" on the
casting.  The two leads might be shorted together due to wear on the
insulation, or the switch might be defective - it has to be open for normal
operation, closed if there is too much boost - waste gate failure - cutting
off the engine at 4000 rpm to avoid mechanical damage.
