So you really are only at like $3500 or so in extras before the normal cost of a rebuild which can be like $3500 or so.
So like $7k
Can you do a full K swap for $7k And have boost ready internals?

You forget to mention you're still left with an extremely flawed engine that has massive oiling issues which will become especially apparent at high power levels. K's are popular for a reason, and the couple downfalls are solved with extremely simple and cheap remedies (type S oil pump, oil pan baffling).
This is all assuming the FB25 will work. If you're forced to run the FA20 block those prices increase a ton.
