ok, first and for most.....i've found alot of conflicting information. are the sleeves nikasil or steel? and before you answer where can i find concrete evidence?

also, if the sleeves are nikasil, is there anysort of special process for honing?

i need to know what to tell my machinest before he begins the rebuild.

Steel, not nikasil.

If they were nikasil, everyone's sr here would be trash can crap from the RAW VOLUME of sulfer in the fuel in the U.S.

ok, i wanted to make sure. i didn't think that you could have such a thin steel sleeve.

is there any way to be positive though? lots of people are positive that they are iron, nikasil, magic ect ect ect.

also, whats the coating on the pistons?
