[Supras] 6000RPM for first time: really good even with low boost

[Robert Pina]

The original nuts for the turbo elbow are not the self locking kind.  You 
should be able to spin them on and then only a couple of turns to tighten.

The ones that hold the turbo to the manifold would be the locking kind.
