Sorry, but that's not right. The J-spec CRX SiR used different mounting points in the engine bay itself, thus creating the market for swap mount kits. A B-series engine will not bolt into any US market pre-92 Civic/CRX body without an aftermarket or custom mount kit, or otherwise modifying the actual chassis mount points.
