does any one know what difference is between turbonetics 63ar stage 2 and 3 exhaust housing is. I was able to find the wheel dimensions for both 2 and 3 but it appears the difference is only on the exducer diameter 2.122 and 2.229 but the major diameters are both 2.559. Does this mean the wheels are interchangable between stage 2 and 3 housing. ?

i am not sure what your exact question is but you need if you have a stageII wheel you need the stage II housing, most turbonetics t3/t4 turbo's on honda's use stage III turbine wheels, might want to measure yours before you go ordering parts, most people also just buy new turbo's, upgrading can be costly due to labor costs.

you need the correct housing for the correct ar.
they also sell the stage 5 wich is like a p trim if i remember
correctly.

I am trying to order a new turbine wheel for my t3/t4. The problem is the housing i have does not say weather it is a stage 2 or 3 and the turbine is damaged. the numbers on the housing are 20358 and 20357

I would call up turbonetics since you will probably want to have it balanced
as well then.they should be able to tell you by the housing part #s
