turbo modification

[Larry C Leung]

Actually, apparently FoMoCo didn't think they could (US) Federalize the
Cologne built hi-perf version of the 2.8 liter V6, so they chose to
modify the 2.3 Turbo from the T-bird (i.e., already federalized) instead,
knowing that it fit as the base model engine (in NA mode) in the Sierra.
They pumped a few more ponies out of the engine and (supposedly) refined
the NVH for a more refined feel in the German XR4 than in the T-bird.
