Hi

I would like to consider upgrading my Talbot Kon-tiki 640/6...2.5 D with a 2.5 or 2.8 Turbo.D......Would be interested in any comments / ideas regarding the mods., involved, and where I might find a s/h lump.

Hi Geoff 2,
If you would like to explain whether you intend to fit a turbo pump or replace an existing plant with a turbo one we may be able to advise you.

Hi Brez:

Thank you for your message, and your kind offer of advice, which is much appreciated.

We are very much newbies into motorhoming, having just one trip to Sthn France, earlier this year.

I know nothing factual, but have been led to believe........That one cannot just fit a turbo pump to a normall aspirated diesel engine, without modifications. ?? such as lowering compression ratio ??

Now being too 'wrinklie' to scramble around motors, I am more to thinking on the lines of trying to find a s/h unit for the local garage to o/haul and fit.
One of the thoughts that come to mind is, will a 2.5 or 2.8 turbo just drop in without and chassis modification?

My outfit is a '91 Swift Kon-tiki 640/6 built on a 2.5 d Talbot express with an Alko chassis.
There are a couple of factors that lead me to seek an upgrade.
1. Less strain on long Journeys, especially when very hilly.
2. I feel the existing power output would not be viable for Cruise Control.
3. I would like to tow a small car.
4. At sometime somebody distorted the Waterpump/Camshaft pulley.
( gives me an uneasy feeling that the pump bearings are being stressed
although I do carry a spare pump, and loads of drive belts !!!!! )

Many thanks.............Geoff.

Hi Geoff,

Give TB Turbo a call and ask for their advice. They specialize in Turbo Upgrades and would be able to tell you if it is possible - or desirable to fit one to your machine.

As a general rule, there is little difference in construction between Turbo and Non-Turbo engines so there should be no problem with respect to the increased power output.

Is it the Pulley that is distorted, or the shaft? Being very short, I would not expect it to be the shaft - so why not fit a new pulley?

Hi Geoff_2

For what it's worth I'll add my views.

I have replaced a non turbo power plant for a turbo unit (2.5) in a previous camper and it is a relatively straight replacement job, I do not think that a 2.8 unit would be a practical option; they are very different from the 2.5. in many ways; the most difficult to overcome would be the mountings. If you employed the services of a garage I think the cost would be likely to be prohibitive.

I disagree with previous remarks reference the difference between OEM fitted turbo engines being little different from a non turbo unit, they have many other mods aside from lower compression. I'm not trying to suggest that the TB Turbo and the like conversions are no good, they are, but they do put extra stress on the unit, a fact they will explain fully to you before work commences should you choose to go along that route. For me the most important factor would be one of braking capacity and performance (unless your base vehicle was a "Maxi" chassis) the Turbo van has 16" wheels the main reason behind this was one of bigger discs and calipers (as well as carrying capacity of available tyres).

Personally I would suggest you think again as to your options, it may be better to live with what you've got until you can afford what you really want (just as long as you are sure of what that is).

I'm a little confused as to your "Water pump/Camshaft pulley” both of these are very out sight unless you have cover guards removed, are you wrongly labelling the auxiliary drive pulleys? they are situated top right hand side of the engine as you look into the bay. If you are carrying spare cam or injector drive belts you are wasting your time as if a cam belt fails, you will need more than a belt to get you going again.

Hi Geoff_2

I have had my Pug 2.5 TB Turboed (2yrs now) it IMHO is one of the best things I have done and although relatively expensive is money well spent.
To the contrary TB Turbo did not advise about problems with more stress on the engine and did in fact explain that the standard engines, normal aspirated and turbocharged, are in fact identical with the exception of the camshaft which apparently gives slightly different valve timing. They test the vehicle on a rolling road before the conversion and give you a run down on the engine condition, they do this as they cover the conversion [u:0e6ee3b447]and[/u:0e6ee3b447] the engine for two years.
I had concerns that as my engine had already covered 60000mls that the extra pressure might be a problem but it was explained that the new turbo was low boost and if you bear in mind that had the engine been turboed from new it would have covered this milage with a turbo giving twice the boost+ and they would still expect it to go many miles further!
So you listen to the information and make your choice, I certainly have no regrets or problems.
I have also met up with others who have had this done with no problems at all. I also can say that I hold TB in high regard for their service the manner in which the workwas carried out as well as the free site and courtesy car use.

Hi Rob.
Many thanks for your message.
As a pensioner TB turbos is a bit out of my class. was hoping I could find a less expensive route.With regard to the pulley problem, the mechanic ( well respected ) who does my servicing felt that it was the camshaft that was bent, he suggested it was a common occurence when undergoing a clutch renewal by someone not conversant with Talbots.
I have arranged to have a closer investigation next spring, if there is no joy on the turbo front.

I really appreciate your help, and advice.............Geoff.

Geoff, If I were you I'd get the camshaft sorted straightaway, if it really is bent it must put an unusual strain on the belt and shorten its life considerably. And if the belt goes so does the engine! Verrry expensive!
