Turbo III
Recent return to 2.2
my understanding is 1989 through 1994 the blocks were common between 2.2 & 2.5
1) How are there two displacements with the same block?
2) Can a 2.5 block be used with the 16v head in the Turbo III
3) Can a NA block be converted to a turbo block with additional machining...
