Hmm, just checked an old Car And Driver (Feb 1993) in which they tested the 911 Turbo S2. They indicate the S2 was from Porsche (specifically indicating that it isn't from Andial - but I am guessing they may have been incorrect). The car is described as being produced to homologate the 911 Turbo race car run in the in the IMSA Supercar Series. The race series required 20 be produced.

Porsche claimed the car produced 322 HP (far from the 380 I had written previously). But C and D's testing resulted in performance that was so great they believed that Porsche was sandbagging -they estimated the true horsepower at 370 HP.

Adrian Streather's Porsche 964 book tells the story that the cars were shipped to Andial for the engine kit and larger turbo charger - after the Andial work was done the car was delivered to the dealer. He goes on to say that the cars were not dyno tested and estimates the power at 371 (but doesn't say where he gets that number from); reiterating that the documentation with the car indicated 322 HP.

The Euro S does look like a more interesting car - much more modified than the S2 - having seemed to combine the lightweight 964 RS with the turbo.

Sorry for the previous mistake.
