60 mph on a motorway?

So you're one of the people clogging up the inside lane on motorways?
My old non turbo 1.8 Escort van would still run at 85 mph on the flat with a run up, and easily cruise at 70 mph.
I fitted a 1.8 intercooled TD lump from an Escort car, and it's transformed it. Will do 100 mph on the sat nav, and comfortably cruise at 85.
Just got back from a 235 mile holding 85 mph on the sat nav (93 + on the van speedo), and it managed it all at 38mpg

Cheap, quick enough, and I hear they run on veg oil and other oily ish products just as well
If you get a whole car as a donor like I did, the swap is very easy.
