All depends on spec , the shafts are still very expensive , add a GpA Compressor wheel and a 360 kit + machining and you have a true 500bhp turbo , ive about 3 of these and reckon theyre a grand minimum. Ive just dyno'd 2 back to back and found all sorts of differences tho , power output and torque spread being the things that matter to me and 1000 rev between the 2 ! Which one is your i guess is the question .
