Help me decide on new setup/turbo
 

Hey guys, so my current setup/build can be seen here:
https://www.miataturbo.net/diy-turbo-discussion-14/custom-manifold-downpipe-exhaust-build-56198/

I think my turbo is starting to die, because I felt much more shaft play recently compared to when it was new. I'm trying to decide where i want to go next, and the main factor is that my current manifold has a t3 flange. I really want a turbo that spools sooner than what i have now, because I am going to start autocrossing in the near future.

This is the turbo I have now:

Current turbo has about 15k miles on it, which is decent for a 150 dollar ebay turbo I think. I'd like to know your opinions on how fast this godspeed turbo would spool compared to my current T3/T4, or how well a 3071 would work. I really want to run a 2871, but that would mean making another new manifold, which I could also do and sell my current setup.

What would you guys do in this situation?

Also, consider this a feeler thread on my current setup being for sale. If anyone wants it, let me know.

Other than "spool faster", what does the new turbo need to do that the old one doesn't... make more power? What is you absolute budget ceiling... total to spend on new parts?

Are you running EBC?

More power isn't a goal right now, because it will be at least 6 months before I have a built motor. Basically my goal for max hp in my mind is between 230-250, and the current turbo isnt very efficient for that goal. I don't have ebc. I dont want to go below 2860 or 2871 in size, because the I will definitely be shooting for 350+ once i get a built motor. Budget for parts isnt too big, but I will save for whatever turbo I end up wanting/needing. Any new parts I can fab and sell off my old stuff to break even at least.
