That last picture shows well how much they have to machine out of the housings to fit the larger turbine wheels in. I hope you have something better than tuneagent dumps going in, the turbine wheels are a larger diameter than the runners on those dumps
Adamness is looking at getting the AMS 4 bolt 3" expansion dumps by the looks from the parity sale thread. I'm also definately getting these dumps. You're right that the Tuneagent/clone dumps aren't quite big enough at the flange when you compare that to the exhaust wheel on the 28RS cores. I can imagine they restrict the turbos somewhat.
Correct! Definitely grabbing some of those and then it will be 3" piping for the rest and some hiflow cats!
