well, I know the cummins applications of the hx35 use either 12cm, 9cm internal wastegated housings or 16 cm non wastegated through out the years, and these are all T3

so maybe there are housings that are T4 for the 35s, i dunno though

i believe most cummins stuff use the 56mm or 58mm comp wheel, IIRC
