Hi there i wrote off my curren (1996, st206)

so got a celica (1994, st202)as a donor car as most parts are the same.
Put all my fancy interior across etc but am not left with alot of odds and ends and a 3sge engine and gearbox which i dont really want to see go to waste.
I have found a cheap Trueno (ae92) which is mint as and just needs the clutch replaced. Wondering if it is worth doing an engine swap and putting 3sge in this instead of the 4age. Would everything bolt up? is the trueno lighter? would i get more power? would i increase my resale value?
If anyone has any info that would be great.
