Noob needin help with setup
 

Saw an ad on local CL for a (turbo kit evo iii gt for 1.8 miata) asked the guy basic questions about parts such as brands but he has no idea what anything is (came with his new (used) car). I have searched a bit for part look alikes but came up dry. If he cannot find any names/branding on the parts is it safe to say is ebay? Obviously this "kit" needs a few things but can anyone identify any parts here good or bad?
Thanks for your help sorry if I posted wrong lel.

I'm the new owner of this lol. The turbo had a bit of shaft play as well as some bends in the compressor side turbine. Overall, its all name brand and good quality stuff, not that it matters since iys off the market lol

Also, thought i'd add. You can clearly see Tial on both the wastegate and blow off valve.
