Hi All. Just picked up an old 1986 4x4 king cab nav the other day running a 2.4ltr. It's pretty gutless and can chew the fuel a bit too. I was thinking of putting a slightly newer more powerfull and if possible more economical donk in it as i am knocking up a camper cab for the back of it which will be in the 250-350kg area. I know every ones got there own opinions as to the best solution but i'm wanting to go with diesel, also 4cyl would be preferred but if v6 looks a better option then so be it. Any help on this would be great. I did do a search to see if i could find any answers so i wasn't just asking the same questions. This did help but only covered very few options. Things that would obviously help would be availability of engine type. difficulty of conversion, cost of engine, and offcourse performance and reliability
