Thanks guys was thinking along the lines of one off a Terrano

I have a D27 diesel 91 navara non turbo , has anyone modified this model of engine am looking to maximise its power for some off road touring .

Had a look at it a couiple of years back , there is a fair bit of info on lpg into diesel on aussie sites, it is meant to increase power and economy, there was a crowd down in Hamilton who do the conversions , not cheap though unless you have a later model vehicle.
