Yes you can
The more technically minded can provide you with the necessary info on what other differences there are regarding any modifying required to work in the bx.
Have you tried using the search function? There's probably a wealth of posts which have already covered this as a few members have done this conversion over the years.

No reason why not. Depending on the donor you might have to swap various parts/brackets to give full BX functionality such as hydraulics.
One thing i would mention, going from 1.7 to 1.9 means a battle with the DVLA who will want a report from the garage that fitted the engine! Eventually i persuaded them i was telling the truth with a wedge of paperwork including the SORN and later scrapping of the donor vehicle and copies of two MOT's.
Then you'll have a fun time finding insurance. A change of engine type or capacity is considered by most insurers as an 'Engine Performance' modification (even if you go from a 1.9 16v engine with 160bhp to a 1.9 td with 92bhp) so you will get stung.

Why ever would you want to do that???Vanny wrote:go from a 1.9 16v engine with 160bhp to a 1.9 td with 92bhp
I had a minor battle with the DVLA too, wouldn't take my word for it so I got a friendly local garage to write a report to state that the engine was changed. There's a fair bit of info around on this forum so happy searching!
RE: BX Engine replacement
Friends,
Thanks for information received.
Repairing my engine must be very expensive: engine is with moderate high oil consumption,turbo is leaking oil & diesel pump is out of tune;also smoke is thrown everytime engine is started.I am using now monograde 40w engine oil in every service .
I would be happy to look for any alternatives to find parts needed to repair actual 1.7TD engine at an affordable cost,and rebuild it as new.
I´ll appreciate any guide and help
Tks

Might have to replace my 1.7 TD engine with a 1.9 TD. Most of the 1.9's available seem to use the Bosch diesel pump (but don't usually include it) so would come with the Bosch injectors - does anyone know if would these be incompatible with my roto diesel/Lucas CAV pump?.
should I make sure I get an engine with diesel pump included?

erm, well, whilst you CAN run a Lucas pump with Bosch injectors, it wont be very happy, will smoke a lot and probably be near impossible to get through an emissions test.
As an aside, and whilst I'm not condoning lying to the authorities, since the 19 and 17 units look largely identical, it'd take someone that REALLY knows XUD's to even know it wasn't a 17...

Smokes lots, because enough's enough already!
Far too many BX's, a bus, an ambulance a few trucks, not enough time and never enough cash...

Doc - if I get one and make sure the Bosch pump is included. and thanks for your thoughts on the other matter..
I've noticed some of the 1.9 engines (Xantia?) don't have the top of the engine 'grill pan' type intercooler that the Peugeot ones seem to share with the BX. Instead they have a large hose that comes right over the top of the engine to take in air near the radiator. If I got one of those, would my intercooler attach to the engine without a problem, or would there be anything gained by adapting the Xantia system?

The BX type intercooler bolts directly to the inlet manifold, so your best (easiest) bet is to swap the inlet manifold over too. Otherwise you'll have to find space for an intercooler at the front of the engine bay, although you'd probably find it's more efficient in that position.
The turbo outlet elbow needs to be changed for the BX variant, or you could swap over the whole turbo assembly (I did the latter, as the Garratt turbo on the BX engine is easier to adjust the boost on).
Flywheel needs to be the BX flywheel, assuming you keep the BX gearbox. You could keep the 1.7 camshaft, or change to a 1.9 N/A cam for more low down torque. That's what I have, but I haven't done a back to back comparison of the 2 cams in the same car, so I can't say how noticeable the difference is.

Hi,Matt
Was your 1.9TD conversion from a Xantia donor vechile ?
I found this Photo of the Xsara 1.9TD engine, as I remember it being posted a while back (Well nearly a year ago, even without use of the search facility) in THIS thread (Courtesy of Kitch).
Has anyone looked into the Xsara as a donor unit for the BX, bearing in mind you'd have to remove the vacuum pump and
replace it with the HP LHM pump (If that's possible using the existing camshaft etc.) ?

Would not a 1.9TD from a Xsara be more suitable as a donor , as the AC/IC is mounted on the top of the engine/cam-cover area as on a BX 1.7TD and possible may fit more readily, has anyone looked into this as a donor unit for the BX ?andycadabra wrote:......(i.e. the Peugeots seem to have the same intercooler)

Sorry, I should have been more clear! Yes, it was from an early Xantia, but it's only 7(?) bolts holding the inlet manifold on so it makes no odds which engine you choose IMO. It'd be a bugger to swap 'em in situ but with the engine out it couldn't be easier.RxBX wrote:Hi,Matt

I woudn't take this engine from a Xsara or Pug 406 because this is a EURO II engine and is less responsive than a normal 1,7 TD on a BX. take it from an early Xantia or Pug 405, even early Pug 306, everything fits in the same place (intercooler, manifolds, turbo unit...), even the flywheel is the same. you will only need a BX 1,9 D camshaft because of the hidraulic pump, in order not to modify the existing camshaft. otherwise, the two camshafts have the same profile and cams dimensions, the difference is at the HP/vacuum pump end. the 1,7 TD camshaft has the cams shorter by half a mm. also you have to keep the old alternator support, the one in Xantia or Pug 405 with aircon is different and will not fit in the BX because of it's size. I did the same swap with a Pug 405 phase II TD engine with aircon and there was nothing else to modify unless I already mentioned
BX 2.1 Turbo D12 coming soon

I'm sure the flywheel on my early Xantia engine was different…it had a pull type clutch as well. Am I imagining or mis-remembering things?khan wrote:even the flywheel is the same.
I would agree with you that to keep things simple, avoid a late electronic engine. Some of the later Xantia and ZXs had an anti theft immobiliser with a keypad; I think the stop solenoid was coded to the immobiliser (or was it a control unit that operated the solenoid?) and protected with a steel plate. To get round it you'd have to remove the plate and either replace the solenoid (or remove any control unit and run the wire direct to the solenoid).
