no, they're not all 13B
there was a 12A used from 79 until 84, I think. Then for the last year of the 1st gen, they put a non-turbo 13B in it.
Then in 86, the single-turbo 13B came around, along with a better tuned NA. Then again in 88, they retuned both engines, giving more power...which remained the same until the 93TT.
I just don't know the serial numbers...
