i have a holset HE351cw.
if you do the math to figure out the trim
((58.6 * 58.6) / (84.6 * 84.6)) * 100 = 47.9793661
compressor
inducer : 58.6
exducer : 84.6

turbine
exducer 57.7
inducer 64.8


the exhaust housing is a 9cm^2 and is a T3
in terms this would be great for a high hp 1.8 and up 4 cylinder or a mid hp 6 cylinder

the compressor inlet is 4" OD and the outlet is 2.75" OD the outlet ID is 58mm
in terms of a pure garret, that's comparable to gt3582r for both compressor and exhaust which is rated at 400 - 600 crank hp and the compressor alone is comparable to the gt3776 gt3782 gt4082 which are rated to ,550hp, 575hp respectively, but the holset has a smaller exhaust wheel than those.

this turbo came from a truck with 29k miles and there is not one ounce of shaft play.

insurance will be required on the shipping

thing can make 42+ LBS/boost and ask for more
as it runs 33 lbs on the ISB Cummins engine

looking to get 300+shipping out of it.
