Smile 89 TTA engine balancing

Does anyone know if the 3.8 turbo engine in these cars is internally or externally balanced?
Thanks, Jim

Re: 89 TTA engine balancing

normally that type of engine is internal balance.
some external balance engine had a counter weight behind the flywheel.(normally the old type engine is external balance. ex 84,83,82,81...etc)
if you see your cranckshaft and see is totally round. that mean that the engine is internal balance.
