I know this is off topic to Sandmans but I have recently purchased a 2004 CV8-R Monaro and interested in maybe exhaust, cold air intake and tune, anyone on here own/owned a V8 Commy , Monaro etc and made these types of mods or any others that they can reccommend etc. Was given this link by a friend http://www.bobromano.com.au/LS1-powe...it-review.html, I know there are plenty out there offering similar spoke with a place at Port Hacking that does turbos and V8 tunes and his price was around $2500. Have also read about changing diff ratio, curious about the ripshifts as well. In two minds as to doing anything care is one of only 320 build and prob less than half were manual so want to keep pretty much original or if I do make mods nothing too radical and something that can be easily reversed if need be.
