With sequential turbos, the setup first makes boost from one turbo alone, and then it switches to making boost from both turbos. This lets you get boost almost twice as quickly.

Two turbos (in parallel) do NOT have less lag than one big turbo. Only sequential twins reduce lag.

Sure, but then it wouldn't be a big turbo anymore (less heavy = smaller).

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
