LT5 bare block

Thanks all! Nikasil is cool stuff. I agree that the ductile iron liners might not benefit all that much but it seems that nikasil would make them a bit slicker and reduce friction. The rotex guys are the only ones I see nikasil coat a ductile iron sleeve and I believe they do it just to get that "last little bit" of durability.


The ford guys "plasma spray" the alum block which seems to be a pretty advanced treatment.


Thanks for pushing the envelope and explaining the engineering!

We have also used the plasma spray coatings on aluminum blocks. It is probably a better coating for aluminum today than nikasil.
