NAPREC is doing all custom stuff. Under Suzuki TA S15 is all NAPREC. They still have all dry sump system and some heads and stuff
Yashio right now is impossible to get an appointment. They are expanding their workshop and now do a rental drift car service based on their YT channel. Yeah I had a friend tried to get their Silvia worked on and basically they don't even bother talking or calling him back. LOL
There is also Yasuyuki Kazama (Best drifter in my opinion) still has his shop
