check the sizes of the main jounals for the two engines, if it's the same then yeah it will fit...

i would suggest you measure your main journals...you might have to do a line hone/bore. If you have the z6 crank for your motor, use it.

Well I got the cranckshaft and it fits good. But the snout is a 22mm and my original one was 24mm. I did some more research on this and so far i found out that 88 and older d-series engines have cranckshafts with a 22mm snout and in 89 or so up to 2000 they changed em to 24mm and that the oil pump and seal is the same size on either one.
So i just gotta get a 22mm cranck gear with the same amount of teeth and i should be good to go! Thanks for the help everyone!

Make sure you get the right crank/cam pulley combo. If not you will bend valves on the first startup. Turn the motor all the way over a couple of revolutions to make sure nothing binds, otherwise you risk your complete build. It has been years since i had to overcome this problem, so unfortunately I can not remember which was which...

Yeah thats something that I do not want happening to my motor! lol I already have a z6 cam gear (38 teeth) So as long as i get a gear that has the same amount of teeth as the original z6 crank gear (19 teeth) it should be fine right?

Thanx for the help Sonictronic!
