[volvooz]

Hi Guys I hope i can get some help here
ive got a 740 GLE 1989 estate with B230E engine, and i would like to swap engines to Diesel / diesel Turbo, and hopefully still retain the auto gearbox

1, can anyone advise what engines will fit other than 740TD ?
2, How much work is required ?
3, Has anyone done this before who could help ?
4, What Problems if any were encountered ?
5, Is there a member who lives near to me in Swansea (sunny Wales)
6, Does Anyone out there have the engine and parts I need For Sale ?

Thanks for everyones help in anticipation
and I look forward to chatting to everyone in the near future

stick with theat lovely engine and go for a gas conversion. theres folk on here who can help you with that :)

Hi,

As above, go gas.
Or go buy a Diesel!

Des. . . ;)

To elaborate somewhat on CTC's reply; if you search "diesel conversion" you will find a reply by Chris Rogers containing the following info:" Rather than listing the parts needed for the swap it would be easier to list the parts you could use from the petrol car in the conversion - most of the interior should be ok except for the dash, if it's an automatic then the gear lever should be ok".
So unless you have 'scrapheap challenge' facilities to hand it's just not practicable.
Good 940 diesel estates are not easy to find, but a well maintained high mileage car will turn up for £500 - £1000. These vehicles are a lot slower than the petrols but do have their own charm, principally the fact that they will do almost 40 mpg.

A Derv conversion will definatly outcost of getting a few 'treats' for your petrol, Either gas it or buy a diesel, If you were to not take any notice of our advise, theres a Water Damaged Diesel on ebay at the moment, Project car maybe?
Best get there quick, Ill be making him an offer for parts!

Converting requires a lot of re-wiring as a lot of the diesel engines mechanics are Vacuum and mechanical (the way it should be) than electric.
Off the top of my head couldnt list what you would have to do, but its too much hassle.

Swapping in a derv engine is a lot work. I'm putting in another vote for LPG conversion

Actually their was a Volvo technical article about 8 years ago by someone who'd fitted a diesel engine, but I think it was an Isuzu if my memory serves me well. It would give you an idea of whats involved though if you're really determined.

Just remember that there wern't as many cheap 940 diesels around then. I think he spent about £2500 doing it and you could buy a good 940 TD for less than that now. The 940 has improvements over the 740 as well.

PS might have been 10 years ago.

1, can anyone advise what engines will fit other than 740TD ? Isuzu 2.8 td (out of trooper)
2, How much work is required ? About 60hours included machine shop work[ making moutings and converting flywheel and other brackets /COLOR]
3, Has anyone done this before who could help ? [COLOR="Red"]I assisted my father to convert 2 about 10 years ago being a 1983 760 turbo manual the 2nd being a 1987 760turbo Automatic
4, What Problems if any were encountered ? Lots as engine was to high in the facelift 760so had to modify crossmember
IN the manual car the volvo clutch was not really up the the torque of the trooper engine and was only lasting about 15000 miles
5, Is there a member who lives near to me in Swansea (sunny Wales) I live in West Glamorgan if you want to email with more questions this is not a problem
6, Does Anyone out there have the engine and parts I need For Sale ? None now sorry as both cars were sold on about 6 years ago when my father passed away

As much as I liked driving and towing with these 7 series with the trooper engines they would be now far from economically viable from doing due to the high price of man hours and some parts.

There is a firm up in Cinderford called Gretton Motors Ltd who used to do convertion They are still listed but now as land rover specialists

I think the best option is to do an LPG coversion and I would thin it be cheaper, and less work.

I believe the Nissan 2.8 & Peugeot 2.5 lumps are used Excalibur Engineering used to do the parts but there long gone.

Sometimes you see one come up on E-bay.

Getting a gearbox bell or conversion ring is the main problem.

I'm sure I came accross another conversion company recently.

But as much as I'm a Diesel fanatic! With the price of Diesel & the work that is involved L.P.G. is a lot easier option.

40 M.P.G. Ha, Ha. I drove like a boring old man for a week over 5yrs ago (probably nearer 10) 16 mile runs not in heavy traffic, doing no more than 50 on the dual carriageway etc.
For a week & got to the dizzy heights of 38 M.P.G. out of a 1990 740TD Manual.
I dont think I could get that out of my 94 940 D24TIC Auto! it would be to painful trying anyway :)

Regards Paul.

I had a best of 42mpg from my 940 TD auto on a run from London to Edingurgh. I kept close to the speed limit though. Cruising between 80 and 90 gave 38 mpg.

P.S. Weird it just posted twice for some reason.

[DLM48]

Well Norwich to Motherwell bringing the brick home and not driving hard but not driving like an old man either and sticking to 'most' of the speed limits in quiet open road conditions mostly Dual Carriageway with some Motorway and nice 'hard' tyres 38 MPG was all we got i was expecting hoping for 40/45. I think someone has tweaked the fuel setting on the IP as it looks like a Vulcan on a take off run when you give it some serious welly but it has been too cold and i have been too busy to get under the bonnet and have a look see in a big way.

regards

[Paul H and D]

Starting to believe that maybe I can get 40MPG but I've never done it yet. Must get that electric fan. Don't think either of mine have been running rich. Only had the D24TIC about a month.

Well at last I managed it 42.3 mpg on a trip to Ireland. 874 from a tank plus a 30 litre splash and dash on the way home. "Dash" not really the operative word on this trip as the vehicle was full to the roof on the way over. Two beds, one a metal disability affair with motors and substantial headboards plus overbed, shower seat plus fixings, drill and all the usual presents and luggage. One overweight middle aged driver, one medium sized oriental and three smaller passengers completed the load which must have been at least half a tonne. I'm sure there have been many heavier loads carried in an estate but this one was crammed. The main reason for the economy despite the weight was that speed was only 60, plus the fact that about 450 miles to Holyhead via Chepstow was done in one go. You wouuld never get anhwhere near that on a commute, nor of course with an auto box.
Anyway I feel that I've got something out of my system on the efficiency front... next it's a year for "pushing the performance envelope".

wow! you did have it packed full!, where did the furry creatures get stuffed? in the glove box? ;)

I tend to get around 38-40mpg, most of which is A roads and motorway and then the dreaded bottom of the M11 and into docklands. On the trips home I have to suffer with the end of the M11/start of A14.
I think I'll be doing a week of nights soon and I'll keep the speed to 60-70 and see what the best I can get is.

My 42 mpg was London to Edinburgh without a stop.
