What do you think is a better option,

Those aren't choices:

60mm Wheel with 84 trim
Housing AR .82

<--- describes the "GT30" exhaust side used on the GT3040R

82mm wheel with/56 trim
Housing AR .70
to4s type housing with 4 " Inlet and 2 1/2" outlet

<--- describes the "GT40" compressor side

So between it all it describes what the "GT3040R" are selling is so you know what you are getting

The turbine housing should be the only thing you need to choose an option on, which .82 would be the go for your needs.
