turbo dosent necessariluy mean performance.. in the case of mini pajero required output is achieved by putting a turbo in a small block engine...
and converting a turbo engine to cng is a difficult task and the latest omegas kits can only do the job( i think so)...
btw alta bhai aapki pajero bohat achi average de rahi hai caz my neighbour had one 6 years back and it gave him like 5~7 km/l
