escort tdi is same to tune as 306dturbo. theres 2 types of pump and i think 2 types of actuator.

tuning guide wise theres a couple of videos done by some bloke in his garage on a 306dturbo which can be used for the escort.

first thing i'd do is decoke the engine and run some diesel fuel system cleaner through and make sure its running right. then to get nearer the 145bhp mark its front mount intercooler, up the boost a fair amount (not sure on psi) and up the fueling a tiny bit off boost and quite a bit on boost and when done right will be a stonking quick escort tdi. was actually planning on doing this myself but bought a petrol 2l focus instead

i dont know if any td engine will do but if you cant find the answer anywhere best bet is to try the scrappies for an escort tdi and use it as a donor. if you can try getting it running at the scrappy first, should be possible with a good battery and the key!
