I have a turbo F22 and the rear engine mount is the automatic version with vacuum. (I did a manual swap in the past and I kept the auto rear engine mount cause I do not had the manual engine mount in my possession.)
with the turbo setup and civic ECU I don't think this vacuum engine mount work anymore and I want to swap the engine mount for the manual version.
so i'm wondering which mount to choose between the #3 and #5 on this picture:

Also, the hole pattern of these 2 mount do not seem to be the same.
is the differents holes patterns are already done on the sub frame?
Also I want to fill the mounts with polyurethane.
I already have the front mount filled with windshield urethane. I want to prevent the engine moving under acceleration but i don't want too much vibration because it's a daily driver.
Is filling all the mounts will cause too much vibration or is it better to just fill only the front and the rear mounts?
thanks
