There was an FC Holden ute in the October 2003 issue of Street Machine that uses a Toyota (roots-style) supercharger on a VS Commo (Ecotec) V6. This particular one came in a kit from Castlemaine Rod Shop. It doesn't say what type of Toyota engine the 'charger was sourced from but I reckon it'd be similar to yours. Give
Castlemaine Rod Shop a try, they may have the right brackets and stuff to mount yours up.
