Okay, so I finished up my sohc to dohc swap the other day and it fired up first try, but I shut it off after a few seconds seeing that I don't have the ps/waterpump belt on.

The reason I don't have it on yet is:

A) I only have the SOHC pully, it fits on the DOHC but has 3 ribs instead of 2, and I don't know if the SOHC and DOHC waterpump pullys are the same diameter, if they were the same diameter, would the ribs really even matter?
B) I don't have the entire PS setup connected because im missing a line and don't want to run a dry PS pump, because frankly, I don't want to wear the bearing in it dry

So, my questions are, can I use the SOHC waterpump pulley on KA24DE?

and will the PS line that runs along the engine crossmember work for DOHC setup, or do I have to use the DOHC line, the rest of the lines are DOHC, the only line remaining from the SOHC is the one running along the x-member. I would go look and compare the too, but, it's -3 degrees outside.

Thanks.
