Hi, welcome to JustAnswer!. This is Ed.

No, you'd be advised to steer clear of that swap.

While the engines seem very similar in appearance, a major change in fuel and ignition management systems occurred in 2003 that makes this engine incompatible with the earlier version. The crankshaft and camshaft position sensor "tone wheels" provide signals that aren't recognized from early-to-late and vice-versa. Although the camshaft tone ring would be an easy change, the crankshaft tone wheel is mounted in a different location on the crank and has a completely different sequence. Changing the cam tone ring is one thing, but the crank is quite another -- can't be done.

Keep shopping until you find something from 2000 to 2002.
