I bought this turbo a while back and I am now ready to install it. I was looking at it the other day and noticed that it is cast with a .63 in the turbine housing, but it is stamped with a .82 on the turbine inlet flange. I called Turbonetics, but I couldn't seem to get an answer. No one knew.

Below are the pictures. I hope it's not a .63 because that will be too small.

Which one is it???

I'll see if I can find out what the build computer has for this unit.

I searched, but didn't come up with anything regarding this problem. If I missed something can you put up the link?

I just shot an email to the managers at Turbonetics and one of them should be responding to this post.

Please accept our apologies but that turbine housing is a .63 a/r
If you need a .82 a/r I can exhange those for you. Please email me at rwynn@turboneticsinc.com and I we will get the ball rolling for you.

I also saw another person posting the same thing here please email me and I will get this sorted for you. Again please accept our apologies.

How much difference will be from 0.63 to 0.82?

How much difference in what? If you mean power it depends entirely on the motor. Given the exact same size motor a .63 A/R housing will spool up faster then a .82 but will be capable of less top end power.
