if your speeking about underdrive crank pulley like the unorthodox racing i'm pretty shure no they are not the same.... just when you look at the shop.hp.com
the unorthodox racing crank pulley only fits on 1.5L
one way you could know for shure is by calling your dealer ask him the part number of a crank pulley(stock) from a 1.5L and the 1.6L if they are the same it would fit if they're not wont fit
