is the compressor housing interchangeble with the backing plate of a t3 , what i mean by this is can i unbolt the t3 front housing cover, ( the one with 6 bolts) and bolt a t34 one on using the same backing plate, i know i need a bigger compressor wheel etc etc but can i do this??? or is the backing plate on a t3 smaller than t34 or is it the same witha bigger housing and compressor wheel bolted on?
