NON OSF DIESEL QUESTION 1.8TD???

[TwoLitrePinto]

yes i know its not an OSF but anyway, i have a mk6 escort van with the shit slow 1.8D engine,

 

it was shit slow until i slapped a TD turbo, intercooler and injector pump on it, it has been flying for a few months and now its gone gutless again, the boost is fine. it idles lumpy, but drives fine at low revs, you can feel the turbo pulling up hill, but when it normally would take off, nothing happens and you need to change gear to drop the revs again.

i think its the pump underfuelling as i dont get clouds of grey smoke anymore when i boot it.

 

i have read that there is a boost diaphragm (think that how u spell it lol) in a little capsule on the side of the pump (front of van) and its pretty common for splitting.

 

i also read that you can get a lot more power by upping the fueling and setting the boost right (already done ) this little diaphragm apparently needs to be installed professionally ive been told, otherwise you risk putting in too much fuel and overpowering your poor little 1.8D,

 

to any diesel specialists out there please where can i get this little diagphragm and how is this done??? i dont care about what i could do to the engine as i got a spare 1.8d lump just without a pump!

thought i might have a play

 

i have asked on Alcoholics Anonymous but had no replies, and im not about to pay hundreds to ave my pump recon'd when thats all the vans worth!

 

thanks

I had a couple of 1800td mondeos.

 

there is a fuel primer on the rhs of the engine that us use when the thing runs dry. the diaphram leaks when they get old and you get air in the fuel which affect power and idle etc, i bodged a clear bit of tube on the fuel pipes to check before i replaced mine to check

 

there is also a small tube that runs from the turbo to the inj pump that controlls fueling on boost, these split so the thing runs, turbo will spin up but its still gutless as the fueling is all wrong.

 

also take the throttle damper off the inj pump (maybe escorts didnt have these anyway?). you can get a bit more power from them by leaking off pressure to the wastegate so it closes later (i.e increasing boost) and by tweeking the injector advance (one of the bolts on top) you can up power a bit but at the expense of smooth idling.
