Hey guys, just acquired a Holset HY35 for the also recently acquired RB20DET. I’d like to run a top mount set up but not sure of what manifold to use/size of the flange on the HY35. Obviously going to need a new exhaust side. Similar or the same as a T3/T4? Help please!!!
That’s going to be one laggy setup dude… but to answer your question they do have several turbine housings, best to search on a cummins/diesel forum for options, you might find a junkyard will yield the housing you want
