Exhaust housing swap worth it?
 

I have just about all the parts on the car I want and plan on scheduling a dyno session at XS within a week or two. This is a stock port motor with an HKS TO4E turbo kit.. here is the info I have on the turbo it comes with:

.84 A/R divided exhaust, I am pretty sure it is a P-trim?
.6 inlet, 57trim compressor wheel

I have been considering swapping the .84 for a 1.0 but I am not sure it will be worth the effort on a stock port motor and only a 57 trim compressor. I did a lot of reading on this thread:

so it makes sense to me to upgrade the hot side since it is relatively easy and I can do it myself. I am not planning on doing a full overhaul/upgrade to this turbo since it is new.. but a simple housing trade is no biggie. Maybe when I do a streetport I will stuff a 60-1 in there. Comments or suggestions?
