I think this engine will be the same as the s16 engine and the later 2 liter 16v iron blocked Mi16 engine. I'm pretty sure a good few people have turbo'd these on www.205gtidrivers.com so it would be worth a search/post on that forum if no one on here knows.

Being iron blocked with no wet liners like the Mi16 it should be good for turbo'ing I would have thought.
