I won't even tell you what other options I'm thinking of are.

First of all, these kinds of swaps always end up as a "Frankenstein" build, where the costs go way over center, and the car ends ups being worth less than imagined. Problem is that Porsche has changed both the chassis and the engine significantly with each succeeding model year, making year mix and match swaps a nightmare, particularly in the realm of the electronics. The very early cars had no CAN Bus technology, but in 2001 its deployment began. By the mid 2000's, the car used CAN Bus widely to run most of the system controllers, and by the late 2000's everything was CAN Bus and there were even more individual controllers involved that did not exists in 2003 cars. Even the fuel delivery systems were totally different.
What most people trying your kind of swap end up doing is getting all of the electronics and wire harness from the model year of the engine, and then retrofit all this to the earlier chassis. Not fun, expensive if someone else has to do the work, an you will never get the cost back out of the car as it is one of a kind and no one except the builder knows how to work on it. We had a customer that swapped a Mezger 996 turbo engine into a early Boxster, by the time it was finished, it ended up costing more than a brand new Turbo car would from the dealer. Not for the feint of heart or wallet...........
