not sure what brand housings will swap with what
turbonetics P-trim turbine wheel is 2.542exducer dia. by 2.92 overall diameter
they make divided ,undivided and on-center housings that will work with it
the highest A/R T4 housings seem to be the tangential divided @ 1.52 A/R
without going to a T6 housing/wheel, and getting it rebalanced
