Anyone know if theres any differences between the b16 (PR3 oil pan) and the the b18 (P72 oil pan)?? Are they both identical, or have different depths? will a B16 oil pan work on a GSR block? or GSR oil pan work on a B16?

 

they are different and will not interchange unless you use the corresponding hardware.
non- vtec b's and pr3 are the same though

 

anyone?? I've heard that the b16 pan will fit on the b18 motor if you're not using a crank girdle, and the b18 pan will fit on the b16 whether you have the girdle or not.. Can anyone confirm this?
