I have a 96 mazda which is essentially the same thing as the 94+ BD 4.5 traditional. I have a 2.5 cowl hood, 18x8 and no modification to the brake booster was needed for me. The wiring harness was moved to the passenger firewall, since there is no more heat/ac and the fuse box was moved to where the battery was. Don't have any GOOD pics, but they can be seen at
