ok to use .48 exhaust housing with .42 intake housing.

I got a t3 garrett turbo off ebay and it came with a .48 turbonetics exhaust housing. The nut loosened up on the turbo, so I am wondering why it did. The turbo still doesnt have shaft play after the nut loosed. Thanks, Austin

How long have you had that turbo?

And which nut loosened up on the turbo?

I have had the turbo for a month. I bought it used with no shaft play. I ran it for 10 minutes then the nut that hold the turbine wheel in place, loosened up.

What happened next ?

I cut the car off, because I could hear the turbine wheel scraping the intake housing. I am getting it balanced and am going to put it back on. I was just wondering is it fine to use a .48 exhaust housing with a .42 intake housing. the turbo was originally .42 garrett t3.

Does anyone one else have a different size intake housing from the exhuast housing?

The A/Rs don't have to match. The A/R's are matched to your flow needs and the wheels inside them, not to each other. I don't think you can even get a .48 compressor housing. A few questions, did you get a new turbine wheel and housing? Why didn't you just go with a 14b or 16g if you were getting a turbo that size?

The turbo is a t3 garrett airesearch. The reason I got this turbo is because my friend bought the car and it came with a blown xspower turbo. So I got the t3 garrett, so it would bolt up to the exhaust flanges. It has a 5 bolt exhaust flange and t3 manifold. When I bought the turbo It came with a turbonetics exhaust housing .48. The nut on the turbine wheel loosened up after runing it for less than 10 min. I am just trying to figure out why the nut would loosen up.

The nut loosened up beause either the person who built it did a crappy job. Or some one has had it apart and took teh compressor wheel off. I forget teh torque spec on garret turbos, but just ahve teh shop that's balancing it make sure that they put sme thread lock on it and torque it to spec.
