Don't want to hijack the thread (admin please delete if off topic) but I signed up just for this info. I was a subaru guy for years and am genuinely curious why GYTR chose this turbo set up. Nate it sounds like you have tons of experience here. Why did yamaha chose an almost 30 yr old turbo design for a 2019 car? GT series (disco potato) 2860rs (that comes in the GYTR kit) is an 80's design. the GTX turbos were launched in 2009 ish and last year the new G series turbos were available. Each series from GT-GTX-G series were big leaps in performance and efficiency and reliability. (esp the latest G series) https://motoiq.com/garrett-g-series-turbochargers-the-most-powerful-small-frame-turbos-on-the-market/
(moto IQ always has some good articles btw)
Not looking for more power per say, but having driven both GT and GTX cars the earlier spool and better transient response of the newer turbo was really really evident and it seems like it would be even more so with the latest G series turbos.
The GT2860 is ~$800
While the new G series replacement is ~$2000

I also realize that my experience coming from heavy cars where max hp was found around ~5k rpm does not necessarily apply to a light 3 cyl that revs to ~10k...
