Sorry, I forgot to mention why I want to change the engine in my van.
My van is a high top Westfalia with a turbo diesel engine, 1.6 liter.  It was great back in ‘86 when it was born but now I am allowed to coast 85 mph here in Hungary.  So the present engine is not sufficiently strong enough, going only 70 mph, and definitely not for the hills of Western Hungary.  

I would like to have it installed for the next summer to visit Sweden and Norway and Finland.
