Thanks for you help,

the mechanical diesel does seem the better choice, is there a tuning guide anywhere

incidently i have owned (and own) a couple of modern diesels
One being a remapped Seat Leon tdi that pushed a proven 143hp .. that was good fun.. but it blew up, rebuilt it with a bigger turbo then sold it

Other is a standard Saab 9-3 TiD 150 thats the wifes!

In the past i have owned several 306dturbos all with mechanical fuel pumps.. one i upped the boost on and it run lush! no idea what figure but it was a quick little light car..

Id imagine 145hp from a torqy derv turbo would be ace in a escort (lighter then saab and seat)... I prefer Diesels to Petrol which is why i have asked

is there a tuning guide anywhere?
will any 1.8 td engine do?
what will i need to do to see 140hp?
