No power steering is god. If you want to keep your A/C you might need to get a diffident bracket for the A/C compressor to fit to the new B16B block. As far as the bar coding goes Ive personally never heard of that. I Purchased my complete swap from a local shop (out side Chicago) for about $3,500 with new axels. My advice is dont take any shortcuts with your swap. Do things the right way. Take your time.
@Jake123. There can be many reasons for going with B16B. For everyone its different. For instance, near perfect stroke, high reving possiblities from factory, transmission, ect.
For me its more that its rare not many people have them. And potentially could be a great sleeper when built.
