what engine to replace non turbo 2068cc diesel?

The Renault Trafic of that era was available with the 2500 fiat engine that could be turbocharged.

 

I have a nasty feeling the Renault gearbox might not be up to the job as there were stories about snapped first motion shafts, thats the one from the clutch to the gearbox.

 

Unless you are covering high mileageswhere fuel cost is critical a better bet would be the engine and gearbox from a Renault 25 2 litre petrol engine with fuel injection. It would provide nearly double the power of your diesel.

 

Unless you can do the job yourself the labor costs would be astronomic.

Having just put a V6 Essex with auto box into a MK 5 Transit, I can confirm its not a job for the faint hearted ;-) ..........

Good point above.

 

It's always mind boggling what you might have to do to put a different engine in a vehicle to what it originally had. These days such things are complicated more by electronic compatibility issues than mechanical ones. This will always be an easier task on a RWD vehicle than a FWD one.

Remember; at some time or an other, someone has fitted a Rover V8 in just about everything so even if the costs are huge..... it probably can be done.

And so does the petrol go at a substantial rate of knots no doubt!!

It would be fair to say my Fanny has a drink problem 8-) ............15 to 17 mpg depending on how optimistic I am with the calculator :D ...........but the Banana only managed 25 ish as I was pedal to the metal all the time ;-) ........... when I started diesel was dearer than petrol *-) ........

 

Nevertheless my actual fuel bill per trip has not increased that much.......and its amazing how much quieter she is, now all I hear is road and wind noise B-) .............

Pelmetman,

 

unless you know your oil pump drive has been replaced take a look at this site.

It goes with no warning at all. I drove Ford Grenada Essex powered patrol cars. I was aware of the problem and hearing the big end rattle dropped the clutch, switched off and coasted to a halt. The force workshop always stripped the bottom end and renewed both big end and main bearings after because there would be damage. The one I stopped was the only one with no damage. On patrol they did about 18mpg

 

A tough old motor otherwise, with more low speed grunt than the later Cologne units.

Not checked the oil pump, but they took the front of to check nylon timing wheel for wear and tear, it was as new apparently so hopefully that indicates that its not a high mileage motor :-S .......

 

Still got an issue with the auto choke as it takes 2 or 3 attempts to start her.........but since having a visit from a couple of blokes from the travelling community.......I'm thinking its a useful extra security device :D ......

 

The more I drive her though the more chuffed I am, and so far :-S ...... well worth the effort and cost B-) ......

At one stage automatic V6 Trannies were being used as what most people would have regarded as riot wagons ( I forget the official label)and were equipped with tough plastic side windows and grills over the windscreen.

 

The 2.5 turbo diesels were replacing them and I remember how hard it was to keep up around town with the manual TD. The fuel bill must have dropped as well.

 

The plastic timing gear had been pretty much sorted by the 70s.

 

Shortly before I joined, my force had also run the earlier Zephyr ( including two with Fergusson FWD) with that engine and but if a couple of teeth came out and everything ran retarded ( valve and ignition) the engine ran very hot and the exhaust manifold glowed red hot.

We restore Citroen H vans that first appeared in 1949 and one of the not so good features is the engine. We have spent a lot of time and money on creating a commercial Ford Transit engine transplant to replace the original 1930's based Citroen version. Although it still utilises the original van's 3 speed, Front wheel drive box, it transforms the van.

However it really is a costly, mammoth task.

 

There are firms that specialise in turbo charging engines, if your existing engine is good, fitting a turbo could make a big difference at not too much expense, relatively?

There were two Turbo versions of your engine, one with a variable Turbo of 92 bhp from about 1984 to 1995 'ish so parts should not be too hard to source for a specialist to use as a base.

The 2,068cc turbo was used in the Renault 18, 20, 25, 30, Master, Saffrane, Traffic and Espace.

Quite a few Espace were specified with the Turbo Diesel.

I take it there is some reason Citroen DS TD engine and later 4 and five speed transmission are unsuitable for the H van. If so it is a pity because the robust car derived 2.5 litre engine was also used in the Talbot Express and there is still the odd decent runner to be found hiding in a rotted out motorcaravan.

 

I had a Citroen Big 15 with the same power unit and three speed box as the H van. I killed it by over revving in second gear. It probably broke a piston ring or cracked a piston as it started knocking and I scrapped it.

 

It was the best sports( indoor) car I ever had due to the bench front seat and no gear lever in the way.

The Citroen H van has the engine mounted like the Audi A4 with the Gearbox between the seats and engine up front by the Radiator, the DS has the engine next to the driver and the Gearbox up near the front Radiator. Traction Avant/Light 15 were the same as the DS.

Talbot has a Transverse engine/box arrangement.
