honda motors

As you can see above, the Si-R B16A driver's side mount is closer to the front of the car. It is also wider, and beefier than the U.S. mount. The B-series mount is designed for a stronger motor, and I suspect that Honda must have put it in that location for a reason.

The other differences are that the passenger side mount, and the front and rear cross members are different. You can import the crossmembers, but the driver's side and pasenger's side mounts would have to be removed and new fabricated mounts welded in. So, contrary to what you may have heard, there is currently NO WAY to mount a B-seies motor in the same location as the factory, without a bolt in mount kit or welding in new mounts.


Keep in mind, that all B-se...
