What's Cheaper??? Turbo or Engine Upgrade?

What would be cheaper for cost/speed?

An engine swap? With all work and everything like that and selling the other engine - I have a stock engine and it has about 100k miles on it. i dont know for sure how much cuz it was changed before i got it and the odometer wasnt touched. i think its called the odometer. well wutever anyways or would a turbo cost less?

I want to maybe spend about 1000.

Please take everything into account - like the money i get from the engine - the labor (or if i could do it myself and have a friend help me [i have lots of car friends]) the extra parts i might need for the engine that you suggest. well thnx for the help

one more question

Turbo. You could do a junkyard setup for around $500.
