I bought this turbo from beeyondengineering. It was used, supposedly had 2k miles on it. Supposedly the turbo is a t3/to4e 50 trim with a .48 a/r and it has a stage 3 wheel. The thing that worries me is on the turbine side of the turbo the gap between the wheel and the housing is about 3 times as big on one side of the wheel than the other.

I didnt notice this at first but when the guy that tuned my car looked at he pointed it out to me. The only thing we can think of would be its a stage 5 housing with a stage 3 wheel or someone tried to port the housing out to make it a stage 3 housing. Here are some pictures, im not sure if they will show anything. But please post you opinions or experiences with a problem like this. I am going to measure everything to see exactly what housing is on it. What if the housing is in fact a stage 3 housing? What is the reason for the bigger gap on one side?

 

very strange? I havent ever seen that before?

 

I don't think stage 5 wheel comes with .48 a/r. I might be wrong.

 

What would be the cause for that unless someone either tried to port it or its a housing from a blow turbo and the fins chewed the housing up in which cause he lied to me.

 

that does not look right to me...never seen a turbo look like that

 

does it spin freely,

if you spin it does the spot that is closest to the housing stay in one spot. if not the shaft is most likely bent.

platinum.

 

It looks like the fins were clipped.

 

check out this pic- stg 3 and stg 5.

the bearings and shaft are fine. it's the housing. I think we have a stg3 with a hacked up housing. hopefully the wheel is OK, which it should be since it has about an 1/8 mile clearance.

 

Blow into it with a air hose and see if it looks like it's wobbling to be safe...

 

It looks crooked. Make sure the housing is fully seated on the CHRA? If it boosts fine then who cares IMO.

throw that thing on there and see what happens. if you got now shaft play and spins freely you should still be fine

platinum.

 

What's the diameter on the exhaust housing? And what's the diameter of the turbine?

 

Bailhatch is going to measure it so he or i will post the dimension when we get them.
