I'm surprised to hear of problems with nikasil. Nikasil has been the material of choice for air cooled 911 engines since the 70's.

As far as autofarm is concerned, their silsleeve liners are steel. Other manufacturers have had problems with head gaskets when interfacing aluminum heads with iron. I would like to hear how their engines fare over the long term and what warranty they offer.

After reading autofarms site, it got me thinking of another cylinder mfr LN Engineering, who makes aluminum cylinders for air cooled VW and porsche. Lo and behold, they have also started to make nikasil/aluminum cylinders for boxster. Check it out here: http://www.lnengineering.com/boxster.html
