I just don't know anything about the motor dont know if the head matches the block.what tranny it is.the code on the tranny is s80-2037652.is it a rare motor.bciz everything I've found about the b16a says its from an sir civic or xsi Integra.im not familiar with these older models.im somewhat new to this and sm learning new things everyday.the head says pr3-4. O/6 just any opinion of wat it is exactly will set me at ease thanks
