The S5 turbo II model has 200 horsepower stock. the s5 NA model has 160 stock. Does the turbo II model have the 40 extra horsepower solely from the turbo/intercooler or does the turbo II 13b have bigger porting job than the NA? The reason i'm asking is, if I get a turbo II swap @ 200hp, put a quality exhaust system and intake on it as well, have the turbo II motor street ported could I expect 250-265 horsepower once it is all finished?

 

cant you get 250 wit a bnr stage 2 and a piggy back ??
some one will chime in but i think u can get that wit a upgraded turbo and a afc2 (i think)
