What B16A's dist.internals are the same as a D15's? I just went out to my garage and I have a dist. from a JDM D15B and a dist from a 1st gen B16A and they are totally different. There is your problem. Who the hell told you that anyways? And if we are talking about an SIR II B16A then I can definately tell you they are even more different. I mean yes they all have a an ICM, coil, rotor, etc. But in no way are they the same.
