Toyota invested a LOT of resources to make the sequential transition as smooth as possible. There is a separate actuator for the prespool...and the oem fuel & timing curves have been extensively 'tweaked' too. Oh, and it doesn't spool back up with the second one after the transition...it spools back up with both.

You don't need a 70mm turbo to make 500rwhp...a 60 would be fine.
