I know nowt about them, other than my mate has an 04 plate 3.2 V6 Vectra C turbodiesel, and the acceleration makes my 24V Carlton seem very tame, even in 6th gear, it pulls like a train at almost any speed.
And quick? bloody hell it's quick! When the Carlton hits the streets in May, we're off for some races tests at Elvington.

So what's all this CDTi, TDi etc all mean?

TDI - Turbo Diesel Injection

CDTI - CommonRail Diesel Turbo Injection

Think the V6 CDTI in the VeccyC is a 3.0 Isuzu lump, not a 3.2

Might be right there, but whatever is in it, it's like greased weasel sh1t when you floor the loud pedal. Saying that, it ain't loud like older diesels!

Which is better then - TDi, Dti, or CDTi or just turbo diesel? :-?

[TheBoy]

They are all marketing names for engines.  For eg, Ford call their current generation of diesels TDCi.


Any modern diesel should perform very well, can be a bit peaky though.

[tunnie]

lots of the modern engines have the 'common' rail injection with loads of turbo pressure, unlike older diesels

Are you saying that Vx were so incapable of design that they nicked more than one vehicle from someone else and marketed it as their own (after f**king it up by ripping half the standard kit out)?

[joshwyatt]

The Vectra C V6 diesel engine is a 3.0 V6 CDTI with the displacement of 2958cc.
Buy a manual and you'll be fine, buy an auto with that engine and you'll be having problems left right and centre...avoid the auto's at all costs.

The 3.0 CDTi is indeed an Isuzu engine......but not nearly as tuneable as the 1.9 CDTi.....much to many Vectra owners annoyance

From what this Vectra can do, does it need tuning?
Mind you, I've not 'experienced' a 1.9. Can they be tuned to be more powerful than the 3.0 litre?

Being completely honest, it really, really surprised me - I thought disiesels were for tractors and odd people!
This thing would go from 45 - 130 in a matter of a handful of seconds, using fifth and sixth gears only - at least, it seemed like it.
I can fully understand the potential problems with it being coupled to an auto box, same as the BMW disiesel-powered Omega?

Most Vectra C's have a large range of auto box problems, not just the diesels either. I can't remember exactly but, it's something to do with oil or water ingression into the box itself, knackering it and costing roughly over a grand to put right.

As to the 1.9's and 3.0, the higher powered 1.9 CDTi has 150 BHP, the 3.0 CDTi has I think 174 BHP and as Mark said, the 1.9 is much more tuneable than the 3.0, good amounts of HP gain from the 1.9 tuning, making it quicker than the 3.0 in some cases. The 1.9 150 has a top speed nudging 140 mph in standard form.

Good God, the world has gone mad!
Even I might go over to the 'Odd Side' for the next motor then.......... doubt it'll be from Russelheim though, probably the Midlands.

The 1.9 cdti is a fiat engine and it's the same engine found in the saab range aswell as i have a 93 vector sport 1.9 TID 150bhp and it flys and with the little box you can buy from e-bay for about £75 you can get the bhp you to about 190

Jeez - that'll do for me! What sort of MPG are you getting with that?

Yes, not much harder to get over 200bhp either!

Beware though, those little boxes are pretty shite, all they do is report an artificialy low rail pressure to the ecu so it runs a longer duration injection pulse.

A proper ecu re-map is much better and can also be used to disable the EGR and only run the increased output when the sport button is pressed.

My Bus (which has the 1.9 CDTi 16V 150bhp lump) gets 54mpg on my commute and the long term (14K+ miles) average is sat at 49 mpg.

you're right, diesels are for odd people and tractors.

someone once quoted listening to a diesel engine as being akin to hearing "a skeleton masturbating in a filing cabinet"

still, they are much more efficient than perol engines, and with modern electronics, the negative effects can be managed quite well. A diesel has won LeMans after all.

currently doing a 1200HP to 1500HP project at work for one of our vehicles. 28litre non-silenced V12 diesel
