I believe the KA block is made of iron...Iron doesnt dissapate heat as well as aluminum or other materials which lead to higher engine temps/intake air temps. The higher the engine temp the less effecient the engine runs, the hotter the oil temps become and the less the oil can safely coat the turbos which could lead to premature turbo failure. The higher the intake temps are the less hp the motor can make from the same amount of air and also the les air can be compressed by the turbo. So on a large level, it makes a difference. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

Josh--I think this is one of the most informative bits of info given about the debate between KA & SR.  I don't think many people have thought about this aspect.
