I'm really enjoying watching this build and find it inspirational. In fact, this build is the main reason I got a 240z for myself...a truly gorgeous car.
One thing I'd like to comment on however is your engine bay. It could just be the lighting in the photos, but your wastegate/turbo plumbing looks to have a bit of a rough finish. In your reference photo, everything looks smoother but things like the two white bottles next to the turbo assembly appear to have flashing/mold lines still on it. Those close-up shots make it quite prominent but further away it looks ok. I just figured since you're detailing the engine bay so much it might be worth considering. Don't mean to "rain on your parade"...
