search businessman24 on sr20forum.com he has an AWD NX (same idea) He has a thread with detailed pics on how to do it. to pull it off you pretty much have to have basic fabrication skills, welding skills, and a fat bank account because the amount of money your gonna spend converting a B13 to AWD, you could buy an EVO,STI, or GTi-R and get change back. a lot of fabrication is required, and not just in the rear end of the car either.firewall, cross member, exhaust, motor mounts,hubs,axles,gas tank and the spare tire well all have to be modified to accept the entire GTi-R drivetrain. not to mention the extra bracing that you would have to add in the trunk for extra support.
