Alpine installed the SC kit on my 3.2V6 crew cab back in 2000. Price was around $2800 at that time. I have since done close to 120K miles without any problems with the kit. In 04, we changed the pulley and upped the boost to 0.4bar. I still have the M62 blower on mine and would love to upgrade to the new M90 kit you guys are busy with.
