That motor is finally starting to show its age, so I've got a '99 block and head in the shop that I've decided to build up with forged rods and lower CR pistons, to deal with a bit more power. Presently, I'm thinking in the direction of twincharging with an MP62 and a GT28xx or GT30xx series turbo. Also picked up a used 6-speed transmission, as they're supposedly good up to about 350 HP. (The early 5-speeds routinely break at 300 HP and below, and mine's certainly making some noise.) We'll see.
