I must mention to you that this set up with t3 t4 turbos is also something that you would only want to use with a completely stock mustang, these turbos will not handle anything more than like 350 hp if you do add these things to a modded mustang you will have problems because the turbos are not built to rev as fast as they would with a modded motor. Just like the guys said up above me you literally get what you pay for.
