I have escort van diesel too. Sory mate but that is all power you can ever had from that engine 1.8 diesel is 44 KW, or 1,8 TD is 65 KW. It isnt made for race, or fast sprints, but is very economical, and saving a lot of fuel comparing with RS. + gerabox of vans is a little modificated (comparing with normal cars) so he can moove easy a lot of weight.
