I'm looking at motor swaps for my 95 hatch and i'm on hmotorsonline and theres a few types of j-spec b16's. i'm interested in two of them: the b16a from a 92-93 integra (xsi) with the same horsepower and torque but for $450 cheaper than a b16a from a 92-95 sirII. if they have the same horsepower and torque why the price difference?
