Title: 1.6/1.9 interchangeability
Post by: foxracer1 on March 06, 2005, 02:47:58 pm: Is it possible to put a 1.9 crank in a 1.6? that would give about 107 ci's and 1800 cc's. Also longer stroke promotes better tourqe at lower rpms.

What about rods and pistons? The 1.6 pistons would protrude from the block a tad more than usual with the 1.9 crank (in other words it won't work). The 1.9 has a taller deck height and longer rods with a higher pin height on the pistons from everything I've heard.
