Thanks, Andy, Jim and John.

Always useful to hear from people who've actually done the conversion.
It certainly sounds as if it would be a safer/quicker route than my proposed Pug conversion with all its unknowns.

That said, I'd obviously take the opportunity to revamp a lot of the rest of the car as well. It gets damp inside (possibly door seals, probably boot seal, certainly rear window), and it's been suffering electrical gremlins, so I might just try a complete loom swap (maybe using the Mondeo loom). This loom has been hacked about for the ERST installation, and I don't want to compound the problems with further modifications for a diesel lump.



The engine would be from an R reg, so only a year later than yours.
But N-P was a changeover year, as I found out when I had to change the cam belt; not many of the diagrams matched the Haynes manual and the instruction to remove the alternator was found to be both difficult and unnecessary (afterwards).

Andy, which "lip" is it that needs modifying? Are we talking about at the bottom/front of the bay? As long as it's not one of the structural parts at the sides of the bay, it sounds straightforward enough.

What happens with the fuel tank. Does the diesel injection pump have integral swirl pot? Could I fit a normal Fiesta tank in place of the injection one I have now?

Does the intercooler need to be moved from its position at the top/rear of the engine bay? It's pretty high there, must be fairly close to the bonnet.
And did you retain the original air box/filter?

55mpg is about what I would expect from this engine in a Q, so seeing figures up to 62mpg is a real bonus. That would cut my fuel costs in half.

Tony.
