As the title really, im reading conflicting info on the internet about the two crankshafts being the same between the 3zz and the 1zz. If this is the case then my 1zz conversion becomes a lot more simple as i wont have to pull the lump out. Can anyone shed some light on this? Also if they are different can i use the 3zz crank with 1zz rods and pistons? It would make my life alot easier if i could just pull the head off and change these over as i can do that in a day rather than 2/3days it would
