sorry guys for all my stupid questions.but that is what you guys are here for?right.

like i said i like to learn. i was listening to some old timers talk.and they brought up chroming.like the inside of the,intake manifold,exaust manifold,inside the cylinder bore.do they do that and what are the effects.or they could be joking with me.they said ferrari does that and thats why they are fast.

is it true????and is it worth it doing??

BMW and Honda have used Nikasil in their motorcycles for years. It's a nickel alloy plating that is extremely hard and wear resistent. There has been an issue with Nikasil and high sulfur (cheap) fuel that affected BMW engines. Usually you see the plating when they want to save a little weight and maybe cost by not running iron liners in an aluminum cylinder. It does look like chrome, almost. You can get your cylinders Nikasil plated, but with an iron block there really isn't a point in it. Datsun casts their iron blocks with a couple percent nickel, so the benefit is already there. I haven't heard or seen a plated intake, (inside). I would think a thermal coating would be more effective.
