So i bought part of an ls/vtec swap off a guy around here and i was double checking all numbers on everything so i know what to the the people im getting a base map from... heres what i know for sure

JDM b16a head
b18b1 block
GSR pistons (p72-AO)
GRS Rods (p72)


nto im having issues telling what crank is in here... other than the 1-4 stamped on it.. there a 4 near the number one cylinder, a K near the number four cylinder and also a B2 near the number one.

From what in understand GSR rond wont fit on a LS crank and they will push the pistons out the top of the cylinder... but heres what mine looks like...
