vw tdi TDI is basicaly Turbo Diesel with Intercooler they come in full range of engine sizes mainly though 2.5 tdi 2.0 tdi
but i still dont exspect that they would not have the same power as some of your amercian vans
you will also find citeron call it HDI thats what i have
fait call it JTD
ford call it cdi
but basically they are all turbo diesels with intercoolers
forgot to say my choice if i could afford one
would be the new volks wagan transporter 2.8 tdi
it has got 175 bhp and a load of torque that would pull a house
What about a smaller school bus.They can be bought cheap, you can find one with a diesel and you can vent out the side. I have not done one yet but it has been rolling around in my head for a couple of years. I think this might be a cheaper alternative to the sprinter van/ ice cream truck. Only drawback you cant disguise a school bus.
