that atleast a stage 9 type-r wheel

 

:P

Doesn't the "stage" have to due with the diameter of the wheel at the bottom vs the top (mayor/exducer.. something like that)... I never read into that stuff very much.

Regardless, that looks pretty similar to a "stage 3" compressor wheel that I used to have.

 

yea its def upgraded, different companys have a different range for stage's ,,

 

Well i ask because if they cant repair the bolt hole on the turbine housing I will need to get a new one. But then Again I guess just measurements will work.

 

it's a stage ONE.

it looks the same as the infamous mercedes/scout turbine wheel.

let me guess:

the base of the wheel is 65mm, it's "stage 1½"
the exducer measures 48.72mm"

as far as it's condition,

radial Shaft play on a t3, The tolerance is 20 mils.
axial Shaft play on a t3, you don'T want any.

rule of thumb, if it's used, have it rebuilt first no mather what!

 

i've only had used turbos and have never had a problem

 

I'm really looking forward to this project. thats a clean nova, I dig the color. Keep up the good work. In my opinion, you should get that bolt hole fixed with time serts as opposed to helicoils. The helicoils seem like they like to pull out like a spring.

 

only when they dont have a bolt in them. helicoils are better than just a plain tapped hole
