i have a box s366 , 66/73/91 divided t4 and an s372 72/74/85 t3.

what i wanted to know, is if i could swap the t4 housing onto the 72 so i wouldnt have to run a t3-t4 adapter to run it on my divided uppipes.

Is the s372 an s300 frame or is it an s400 with a small cover? Post up pics of each.

looks like the 300/400 hybrid charger, so yes they should be interchangeable. Try it and see...

what turbine in the 72? 74mm exducer?

according to bullseyes website, you are correct on the 74mm exducer.

for fitment, is it a go or no go type deal? will i know as soon as i put ot on if its going to be ok or not? ive taken turbos apart, but never swapped parts back and forth.

yes, its very cut and dry. If it clears the wheel, and the bolt holes line up and it fits the center section, you are in business.

some people call that turbine a 74, some call it a 73, some call it a 73.5.

pop the housings off, mic the wheels, and interchange as you wish as long as everything looks good

The 73 and 74 use the same housing, the 73 is just clipped, where as the 74 is an s400 wheel and is straight blade commonly known as an 83 turbine.

so what housing do i need to buy and where is a good place to get one from?

what options do i have in sizing?

also, i went back and looked at the turbo i bought. he said it was a s472, what difference is there from the s472 to a s372?
