Do all 2.1 TDs have Lucas pumps?

My brother is considering turning over a new leaf, mending his ways & swapping his 306TD estate for a 406 estate. He fancies a 2.1, ('HDi's are nothing but trouble'). AFAIK 2.1s only came with Lucas injecion pumps, but can anyone confirm or deny this?
(ServiceSucks seems to confirm it).
He won't have anything with a Lucas pump, cos:
A). Wants to use veg oil
B). He's convinced the Lucas pump is why he keeps getting towed home by them unreliable HDi's

Apparently you can't use veg oil with the 2.1TD's. you'd need a 1.9TD with a Bosch pump.
Easiest way to check is to google and check WVO websites as that's how I found out about mine.

Mine has the Lucas pump as did my Xantia before it.
Ran the Xantia on oil a couple of times with no ill effects but think damage occurs with consistent use.
Considering the low engine numbers built I would think they all had the Lucas pump.
Boo.

I have been led to beleave all 406 2.1's have the Lucas EPIC pump wich will not cope with veg (that's why I'll be running mine on BIODIESEL) but the 605 & citron XM 2.1's are fitted with a Bosch pump wich will be fine with veg, so if he can find a 605 or XM pump with injectors and injector pipes and swaps them over he should be fine.
Ask on
www.vegetableoildiesel.co.uk for a definertive anser about the swap.

Thanks for the info guys - I've checked the links suggested etc. & others - all confirm Lucas pump / don't use WVO.
Following beer-fuelled strategy session, he's now thinking 1.9TD with mild tuning. I've heard it's relatively easy to get these up to about 110/115 bhp by fuel pump adjustments, injection timing & mods to turbo/wastegate plumbing. Anyone got any experience of this?

I've done it on my 405 1.9 TD (Lucas pump) and had good results.
Do a Google for "John's 306" he has a diesel tuning gide on there.
I found adjusting the turbo waste gate was a PITA so fitted an adjustable boost controler (from ebay less than £20) and this was easier as you can adjust it in minits whithout fishing around under the car.

Thanks for the info, Mark - I've looked into it & a few other places - seems there's a wealth of 306 tuning info, but few references to 406's. Still it's a good start, now I know what to look out for.
