Peugeot XUD9 1.9TD into Series 3 - anyone done it?

[MisterC]

I know Steve Parker does a conversion for the 2.5 NA and TD XUD3/t Peugeot engines, but I'm a big fan of the XUD9 1.9TD Peugeot engine.  It appears on the face of it to be an ideal candidate - 92PS, loads of torque developed from 2100rpm onwards, mechanical fuel pump - no ECU to worry about, shed loads of em around, legendary longevity (apart from a few 406 1998 engines).  My 806 has this engine and is a big old bus, which it pulls easily.  I've had one in a 405, which was superbly reliable and economical.  I'm sure the reason noone' done it, is because you can't, but I'd like to know if it is possible (relatively easily).  Discuss...

Would you want to be using this engine off road?  Bottom end power is the importaint thing for that.

The Pug engines are very good but i would be consernered about bottom end on the 1.9td below 2000 rpm (standard 2.25 petrol has max torque at 1800). Most of your off road driving should be done at low revs.

For road use it may be a good option, although i would be supprised if the economy was any better than the 200tdi.

Good luck if you go for it, would be interested to know the drivability after.

I use my SWB S3 for my daily 46 mle round trip to work, so it would be mainly road use.  I'm up to 23 - 25 mpg with all the mods I've done so far, but still a bit thirsty for my liking.  My final push with the 2.25 petrol is to fit an elecctronic dizzy and SU carb.  If I can get upto 30'ish mpg, I'll stick with the petrol, if not, then I'll look at a diesel conversion (the usual suspects, 200tdi, prima etc).  However, the current difference between petrol and diesel is about 7p per litre around here, so any conversion has to give 35mpg at least to make it worth while.  I really like the pug XUD9TE engine, but if there isn't any knowledge on how to do it, I'll keep it simple and safe with a proven conversion.

I'm truly impressed if you're hitting 23-25mpg with the engine running properly and tuned as it should be.  :shock:

2.25 Litre Petrol engines are hardly known for good economy.... if not worse economy than a Rover V8 in the same vehicle.  :lol:

To get to 23-25mpg is an accumulation of all the standard economy mods, i.e. kenlowe fan, fwh, 750 tyres, weber carb, ignition amplifier, overdrive, in-line fuel catalyst.  If you work back from the percentage gain that each mod (supposedly) gives, then I reckon without any mods it's doing about 16mpg.  Also the fact that I do a longer daily journey on A and B roads, with not many holdups, helps.
