Yes and no... as a direct replacement no. The cranks are different between the two, which will throw off how your accessories mount up. The VG33 crank pulley won't fit on the VG30 crank snout and the VG30 crank pulley won't line up with the VG33's accessories.
From there, you have two options. You can either put the VG30 and its own accessories into the '99 or you can put the VG33's crank, oil pump, timing sprocket and cam gears, oil pickup, oil pan, oil filter block plate, crank pulley, accessory brackets and accessories on the VG30 block (along with any other needed swap parts like intake and exhaust manifolds, clutch and flywheel, etc.)
You can definitely make it work, but it will take quite a bit of work to pull off and either way, putting the VG30 in the VG33's place will cause a loss of power. Personally... if there's something wrong with the VG33 I would just replace it or rebuild it. There are a ton of those engines listed here: http://www.car-part.com
