Swapping Turbine housing on gt3071r
I was wondering if anyone has swapped to a .82 a/r or 1.06 a/r turbine housing on a gt3071R. I was thinking about switching to the t4 .82 a/r so I can also use the V-band exhaust fitting and fit a new exhaust manifold that I just purchased. Any info helps, thanks for looking.

If you have a 3"turbo back exhaust and you are running a healthy amount of boost, you should swap to the .82. In these conditions, contrary to popular belief, you will see better spool and more top end with only a slight loss in torque before the turbo begins to spool.

Yea, I have a 3 in exhaust from the turbo back and I plan to push about 30 psi if all goes well, thanks for the input, hopefully I'll have it swapped by the 10th or so next month.

The turbo is in good shape and I like the response, but my current manifold is cracked and the new manifold is for a t4 turbo, the turbine housing is like 300 whereas a new turbo is like 1500 or so, I figured swapping housings would be more cost effective.

Where in VA are you? I think the Houseing switch is much better then a new turbo lol. Also look at FP they might do more then a Houseing and also a little more $ and its a HTA turbo which is allot better.

I may see what they can do as far as a rebuild, it depends on how everything looks when I pull the turbo to put on the new housing and exhaust. I live in Gloucester.
