The turbo etc was never fitted . They changed the manifolds over i suppose , this was around 4 or 5 years ago now i think , maybe less. Not sure about the gas either. If i was thinking about puting a 7mgte in it , id prolly get rid of the whole gas system. Hasnt been run on gas for a while, i think because of bad idle etc. so it might be the mixer thing into the inlet.
