If it's a 2000 model jdm STI, that would have an ej207 engine. That engine has better heads and pistons and bigger turbo than the 02-05 ej205 we got here. If it were my car and my money, I'd swap over the ej207, and have an 02-05 ej205 wiring harness merged with your 99 L's harness. That way, you can run the ej207 but also have a fully tunable ecu, or tune yourself with a cobb accessport.

The ej205 harness will run the ej207, but you need to make a couple changes. First, need to swap the crank sprocket, and the one timing sprocket that has the timing marks on it. Then you need to swap over a loaded 02-05 WRX intake manifold with wiring harness. Then install the 2002-2005 WRX ecu in your merged harness, and get it tuned! When I say 02-05 WRX, I mean North American model car, not a JDM motor from that year range. You should be able to find an ej205 with spun bearings or slipped timing belt for cheap if you're not in a rush.
