Hello Marcyg,
The 1.8 cvh Sierra uses the same 88mm stroke crankshaft the 1.9 engine uses.
The north american 1.9 has an 82.0mm bore size. I believe the 1.8 Sierra has
the 80.0 mm bore size. I am not sure if the small bore Sierra block is taller than the regular 1.6 block.
The cranks are the same, and the blocks are different.
