I'm wanting to find out if the BNS engine in a B7 RS4 can be replaced with the later model CFSA engine from a B8 RS4 or RS5? The later model only came with the auto and no manual option so I'm wondering if the Getrag HLD/JMH 6 speed manual will bolt up to the later CFSA engine. Obviously the flywheel / clutch assembly would need to also bolt up to the CFSA to replace the torque converter. Has this been done? Is it technically possible?
