ok i am thinking about buying a 90 civic dx h/b with a "swapped si motor" how do i tell if this guy really did put the si motor in? what are the cosmetic differences so i can make sure he is foir real. i think he swapped the same generation si motor in but i am not sure. the car came stock with a D15XX and the new motor should be a D15A6? thanks--david (new to the honda game)
thanks but how do i tell the two apart in the engine bay? are there any cosmetic differences? and where is the engine code located i know in B series motors it is in the front on a mount near the header right? are D series motor numbers in the same place? thanks--david
any that i've ever seen have the block stamping in the same place, right on the block facing the radiator, by the header right where it mates to teh tranny
