Anyone have any knowledge or experience with Nikasil coated engine cylinders ? I was talking to a fellow the other day who is building a snowmobile and is building an aluminum V8 engine that will have the liners removed and Nikasil coating applied. He says the engine may be as much as 15 lbs lighter after boring the block oversize and applying the coating. Porsche has done it with turbo engines, but Jaguar failed because of sulphur in the gasoline. With newer low sulphur gasoline and mandated even smaller amounts, it might be a way to lighten some engines.
