Up to you if you think it's worth it though, save a grand by not fitting a turbo back? Maybe just get a custom down pipe as that's apparently where the restriction is. 240bhp from a ko3s at 16 psi, how did you get that figure, dyno machine? A ma on the Audi forum was running mega high boost of 24psi with 230bhp, but 290lb torque, he did turn it down for his turbos sake, most agreed real figures for stage two are around 225bhp with 240lb.
