Is the SH oil pan the same as the base?
are all h22 oil pans the same?

or is the SH just different

 

Check at places like slhondaprts.com or hondaautomotiveparts.com, the base and SH have the same pan.

Also, for the 5th gen they switched to an aluminum pan.

this is true, i found this out when i ordered a steel bung to weld on and then, of course, i ended up needing an aluminum one on my original 5th gen motor.

 

Also, as far as installation of the pan goes, you only need to use a silicon seal for the 5th gen pan and not the gasket used on the 4th gen (just in case you're wondering that when you put it on).
