You can install any year 5mge into your 82 car. The blocks are identical, with the exception of the casting marks on the outside, and the fact that the 82 block has no provision for a knock sensor. The heads are identical as well. Use everything from your 82 car, with the exception of the head and block, and you'll be set. I suggest you replace external seals, water pump, timing belt, etc while you've got the engine on a stand. Also, it would not hurt to check the bearing in the bottom end. While you're at it, knock a hole into the oil pan, just in case the turbo bug bites you at a later date. Hope this info helps.
