No, but they are very similar.

BUICK Vs. PONTIAC TURBO ID - The 1978/83 Buick V6 RWD turbos appear very similar to the 1980/81 Pontiac V8 turbo. They do not interchange. They can be identified by the three mounting bolts on the compressor outlet. The Buick's form an equilateral triangle each spaced 3 inches apart. The Pontiac's are 3", 2.5" and 2.5" apart. The Buick's compressor A/R ratio (stamped inside the outlet) is 0.42. The Pontiac uses a 0.60 compressor A/R.
