question about new crankshafts

[KaLo_o]

i just have a simple no0b question about new crankshafts.... when i look on extremepsi or anywhere else for a crank... there is a mesurment in MM for that crank...like 88mm, 94mm, 100mm Etc.... can somebody tell me what this measurement is exactly?

Stroke. 88mm is the stock stroke for the 2L.

100mm is a 2.3L I believe.

I beleive that is the stroke.

88mm is a stock stroke length for a 4G63 2.0L
94mm is used to create a 2.2L 4G engine
100mm is a stock stroke length for a 4G64/G4CS 2.4L, and is used to make a 2.3L stroker when used inside a 4G63 block

Stroke is the distance that the piston travels up and down in the bore. The crankshaft's rod journal centers are a distance of 1/2 the stroke from the center of the main journals.
