i would like to no if b16a 92-95 sirII and a b18c1 oil pans are the sam and if the gsr oil pan will fit and work on my b16a sirII. because mine is dented and i have
a blown gsr motor so i was wondering if i could swap them......

 

b16a and ls are the same. the gsr and ITR are the same. tomy knowledge you can't use a ls or b16a on a gsr or r cause it is too shallow and won't clear the girdle however you can use a gsr or ITR on a ls or b16a but you need to use the gs or itr oil pickup.
