      would either of these be a good turbo for the stock internal setup 360/400hp and would they be pretty much bolt on, ie minimal fabrication of downpipe ect.

          I don't know the exact spec, but as the turbo shop spends alot of time and money testing different combinations to get the best hybrid they aren't going to be telling anyone what components are used. You should talk to Hoffer about the options, as there are a few different hybrids, and I'm aware PRJ has done custom mapping on at least 3 of them.

          What I can tell you is the one I use has a K26 #6 hotside and the coldside wheel is about 58/78 mm, very similar to my old K26/7 (slightly larger coldside wheel but otherwise it looked and measured the same). However it out performs it across the rev range.

            question for PRJ.
            i remember speaking to hoffer late last year when you came down to map a few forum member's cars,unfortunetely i could not attend.
            i have a MD357 roller bearing special kkk hybrid turbo from Dynamic 450bhp.
            i believe this turbo is a torgue monster.
            what is the maximum bhp that's can be achieve on a standard Rs2 engine once map properly?

              I am not a fortune teller, I am sorry
              Map it -> then go measure it, and you'll know what it'll do.

                  Asking is always fine - I just have never mapped anything with a such turbo, so I am not familiar with it, neither do I have dyno graphs.
                  So I can't answer your question.
