ok, i already tried searching for this however i was unable to locate anything. its kind of a weird question, however, i need to know the sizes of the crank pulley bolts for the following motors

gsr
ls (a1 and b1)
b16
d16
h22

im pretty sure the d series all have 17mm bolts and the b and h series all have 19mm, however this is just an observation from working on a few motors in cars ive had.

any info on the correct sizes would REALLY be appreciated.

 

d-series= 14x 1.25 (17mm head)
b-series= 14x 1.25 (19mm head)
h-series= 14x 1.25

weird hugh?

 

thanks
