A diesel 306 has found its way onto my shortlist of potential daily drivers when I change cars. But I've noticed that while the D Turbo is lauded as a daily runabout, I've never seen the more powerful HDI mentioned. Is there a reason for this?

the turbo in the earlier car comes in at once and gives the impression that the car is faster than it is,still great though. the turbo in the hdi comes in more gradually

Is it not the timing as well perhaps?

The D Turbo was the early one, circa 1997 I think? Back then 306's look fresh, new and 'cool'. By circa 2000 when the HDI came on the scene, it looked a lot more dated, so people were not so taken by it.

Just a thought.

because Dturbo was a model like GTi-6 or XSi and came with both the XUD9T and the HDi engines.

Plus VW, BMW and Audi had all started bringing slightly sporty diesels to the UK by that point I guess...

The early Dturbo/tds are easily tunable if that is your want. Just dial in half a turn extra on the fuel and away you go in a cloud of smoke. The HDi was a common rail engine so is quieter, smoother and better MPG. Not so easily tuned.

I think it is the easily available "free" power of the Dturbo that makes them the one to go for. I certainly enjoyed mine and kind of yearn for another one.

Would you not run the risk of destroying anything? And how much more power do you actually get, considering the HDI is already 15bhp better off?

I thought XUD 1.9 TD was 92hp and the HDI one was 90hp?

Are they pretty reliable cars? I'm tempted as well but Peugeots record does rather put me off

They HDI has less power in the 306. In the 406 it had an intercooler which gave it the extra power. But not in the 306. It needs the more modern remapping stuff to get going.
The earlier TD unit is a bombproof engine. It really is as easy as a turn on the fuel pump. It creates more smoke but turn it down again for the MoT if you're concerned. If you've more time and cash mods can be made to the wastegate and intercooler. I can't remember how much power was gained, but it was noticeable and you'd have to be a monkey to break anything.

Not sure of the respective power outputs, but going back a while I owned a 306 DTurbo and over the years have driven several 306 HDi models.

Although the memory is probably not quite as sharp as it once was, I seem to recall that none of the HDis felt as quick or as punchy as the DTurbo, nor as involving to drive.

Early xud9s (the earlier type of 'dturbo') can get head gasket problems. Later xud9 engines are bulletproof. The increase in boost and fuel pump gives 10-20 bhp, so you can reach 110ish bhp.

As said, the HDIs are 90bhp as std. Remapping them without an intercooler can give 110-115 bhp (mr whippy did his), fitting a FMIC and increasing the boost car get you to 140 or even 150 bhp.

The HDIs are quieter and feel less pokey due to the smaller turbo, but are similar pace to the earlier std dturbos. The have less of a young person's car image, which makes them less popular, unless they're a late (HDI engine) dturbo, which had the GTI6 bodykit, interior etc.

But is bloody costly to get there.

I have had x2 306 D-Turbos, the first when I was 20 the second at 28. I concluded that they look better than they drive 2nd time around. A hugh disappointment. I would personally go for the MK3 Golf TDI which in stock guise handles better than the 306 IMO.

IIRC, The D-Turbo was sporting model, with stiffer suspension, alloy wheels, etc. At the same time they also produced models suffixed -dt which were non-sporting versions with exactly the same engine.

The HDI then appeared which replaced the -dt models and at the same time the D-Turbo was upgraded with the HDI engine but the D-Turbo name remained.

So basically buying a D-Turbo (whether 1.9 or HDI) gets you the sporty bits attached to a diesel engine, which is still rare in their price range.

Are these actually supposed to be in any way quick? I have a renault 19 td as a shed(ie same engine) and its incredibly slow - no signs of any problems though. It can barely maintain 70 on motorway hills.

Apart from the DHY engine codes made in 97/98 that had a most unfortunate habit of pushing con rods through the block! Most of these engines were used in 306s.

The HDi suffers from a poxy dual mass flywheel (at least the later ones do), and a complex and expensive to fix common rail injection system compared to the agricultural, but supremely reliable (apart from the above!) mechanically injected XUD.

If you get the XUD9 engine with the Bosch fuel pump (not the lucas one) you can put vegetable oil in it
