Shame about the starting price, is that actually a fuel injected car?

It is indeed, albeit a single point injection with a catalytic converter, no more hot starting problems but they are slower than a carb fed one (and note the metal bonnet)

Rare tho. But too much money and its location would put alot of people off, plus as we all know non 16v petrol bxs have a limited market.

A nice enough looking BX but not a particularly sought after model, as you point out, Tim. Hardly a barn-stormer, but probably nice 'n' reliable. Neat.

I think it's way over-priced though. Why not start low and put a reserve of say, £400 on it? Then, re-list if it doesn't reach, and then if - again - it doesn't reach put a £350 BIN/BO on it. A lot more realistic, I'd say.

Agreed Phil, its worth the same price as a equivilent K plate sierra/cavalier in good nick with nice miles, £500 max imho. Would look nice with some speedlines.

Agreed there Tim!

I'd never have a Carby car. Hate them with a passion. So inefficient when idiots use them around the suburbs and then can just be so cranky. I also hate having to give them a bit of throttle on starting. Makes the car sound so old fashioned.

Don't be fooled by Mono-Point EFI. It's surprisingly good. There's also only one injector to foul up not four too!

We have Mono EFI on the Mk1 AX GT and it's a real hot hatch with that setup. Beats a 16V and most Skylines without a sweat. Pity you guys didn't get this little rocket over there.

Getting back to the TXI. Very rare, don't hear about them very much. Looks like a really nice car too.

You had no choice but carbs on the non Gti cars until 93 here when the catalyst law menats people went to Efi.

Carbs are ok if set correctly but are prone to problems on BXs when they get older. Saying that the Jetronic system can be problematical.

The biggest problem with carbs is they are unable to meter the fuel as accurately as an EFI system, so the motor is less efficient.

As Tim says, Fuel injection was considered as a go-faster system on UK cars.

It was only available on up market / GTI versions of cars until 1992/3 when the catalyst became a legal requirement and EFI was needed to make the catayst operate reliably.

EFI could have been fitted to all cars many years earlier, giving an improvement in fuel efficiency and pollution for everyone. But cars would have been a bit more expensive to make.

can efi be retrofitted to carbed BX's?

Anthings possible mate, its just down to getting the parts and the cost, Bearing in a mind a 1.6 306/205 Gti etc is basically the same engines.

Wonder if anyone has done one before, if its easy & cheap enough to do, it might save a few more of the less desirable models from becoming extinct....

That Mono EFI system can easily be fitted to any 1.6 of the same engine. Usually you'd need a donor car to get the EFI from. So the EFI from that TXI could be fitted quite easily to a 1.6 meteor or a 16TRS or something similar.
Because it's Mono-Point there's not that much to it. Mono-Point on BX's and AX's don't actually control ignition whatsoever, just the fuel input. I believe that's the same with Jetronic, however, Motronic controls the ingition too.

There would be one stand alone loom knowing Citroën for the EFI and you'd need that plus the ECU and manifold. The rest is there.

Have fun though.... I'd say buy a GTI or a TZI if you really want EFI.

1987 was when there was a law that from that year on you could no longer sell a car running leaded petrol. I don't know when it had to have a catalyst though. The BX here had them from 1987 on (All MK2's).

Expensive to make?? The base BX (19 TRI) was 15,500 pounds new here. The 16V tipped about 20,000pounds AFAIK. So it should have EFI and every gadget known to man. HAHAHA

I have a 1992 BX price list, and a BX16V costs about TWICE the price of the cheapest BX model !

Citroen must have made most of their profit on the higher spec cars.

Jetronic does not control the ignition on the BX,
So it would be easier to retro fit.

But I would not bother doing it myself because a GTI gives you other desirable features, straight out of the box, for very little money and no effort.

Catalysers were very rare in the UK until 1992.
