Why does the SYKO kit require the use of the R33 Skyline GTS-T cross member?
The mounting pads on the KA crossmember sit too far back to properly line up the RB. All other kits available use unattractive “angle iron” looking brackets (running front to rear) to mate the two. From a design perspective, this is less than ideal for handling the high levels of torque that the RB can produce. Not only does it put stress on the conversion brackets, but it also adds stress to the mounting point on the crossmember. In short, the brackets add leverage to the torque of the engine much like grabbing a longer breaker bar to loosen up a tight bolt. Thus, the use of the factory R33 GTS-T crossmember is part of the solution. As the mounting pads on this crossmember align perfectly with the engine brackets it makes for a superior design. By adding our polyurethane conversion mounts, the engine is positioned lower for an improved center of gravity and further back for better weight distribution.
