fitting renault 1.6 diesel to volvo 340??

[debbie]

hi all..

we have an 82' 340, 1.4 petrol.. (the renault engine) (rwd)

we also have a 94' renault extra 1.6 diesel we are breaking up..

apparently, the engines in these were fitted to the volvo???

can it be done?? easily??

thanks. deb xx

yes, can be done if it's an F-series based engine but the vacuumpump on that diesel is at the back of the cylinder head, that won't fit with the heater housing/firewall.

in the volvo 340 the vacuumpump was a special design placed on the right lower side of the engine to solve this, this pump hasn't been connected to any other car model that has the same thing yet so they are quite rare!

al this means that you can fysically place the engine, but wont get the vacuum brake assist

It may be possible to use a peugeot vacuum pump, belt driven, (like the alternator)
THis is commonly done on landrover diesel conversions.
The pumps were found on early 206-306 diesels (probably more) Im not sure on alignment of belts, but im sure somthing could be shimmed up. If the 340 doesnt have power steering then that mount could be used. there may be an aux/unused block mount somwhere, on the 360 its on the lower left hand side of the engine under the pas pump.

Hi there, how did the conversion go? or didn't it? i am interested as i've been thinking the same for a while. is there not anyway you can bodge the 1.4 vacuum onto the diesel?

1.4 creates its own vacuum in the engine, diesel works a bit different hence it needs an external vacuumpump for the brake assist serve

[wilbo8711]

what about one of the more modern renault engines? they still start with F so i assume they would fit? they're a pretty cheap engine to buy second hand. 1.9DTI for exampe? would be quite powerful and still very efficient!
Dai?? you seem to of tried most things!
i'm looking to do a conversion in the new year. i have a short attention span! only had the volvo a month

Hi all, been reading through the topics to see if there was any info I could use, decided to post on here. Just looking for someone to clear up a couple of details for me:
I have a 440 1.9td. Engine is sweet but body is scruffy and scabby.
I saw that some people are (talking about) doing a conversion to the Renault diesel engine I have in my 440, but from the homework I've done it says the 340 is RWD with the gearbox slung out over the back axle, and I know my 440 is FWD.
Is it an "easy" conversion, I mean, do the 340 gearbox and the Renault engine bolt straight together? How does that happen - Is there a propshaft from the engine to the box?
Is there a RWD box that bolts stright onto the engine, so I could shoehorn one into my '84 capri? Would be able to use it much more if I could afford the fuel!
Thanks,
Tony

It's easier in a 300 than a capri, the block on your diseasal is the same as our 1.7 engines.

However, the problem you have is we have transaxles, gearbox at the back style, so whilst the clutch cover from a 1.7 300 will bolt onto your diseasal, it's not a gearbox. Through in a propshaft and bolt a 340 gearbox to the capri's boot floor and it'd hang together, the wheels just might be in the wrong place On the plus side, the diesal might rev higher than a ford V6

It's a conversion I'd love to see done in a 300, what sort of MPG do you get from your 400?

Drove it from Bristol to Ayrshire, took over 7 hours. Mostly stayed at 70, thought the needle did creep up to 80 (and once or twice 90) when I wasnt paying attention! Only used half a tank of diesel, and when I did the maths it worked out to round about 60 mpg!!!
Wish I'd bought one of these years ago, I'm loving the comfort, safety and fuel-sippyness.
Actually bought it for the fiancee, she has an 80 mile round trip for work and needed something safe that could handle the miles.
I'm quite interested in the 340 diesel engine swap, though.
I've heard the GLT's are very comfy, and I know the (original) diesel versions werent sold in the uk, but if its possible to sink the Renault lump into the 340 I'm all for it. Anything in particular to watch out for? Anyone done it?
Thanks,
Tony

Few people have mumoured about it (me included... I think it'd be an awesome swap). I've done something similar, ish, I have a 480 turbo engine in one of mine and a Clio Williams engine in the other, so the diesal would complete the set, both these are the same block as the 1.7 340 and your diesal

I've shattered a bellhousing and prop recently, found to be because of rear engine mount sag (bigger head, manifolds, crank, pistons in that order) I imagine you'd have similar issues. Because the prop has no UJ's, it has to be perfectly in line. I'm going custom engine mounts and prop now, but have done 20,000m on the OEM 1.7 parts. FWIW as long is it isn't a daily, I'd bolt it together and run it, see how well it works. If all is good, then go for the same custom bits (which may even be on the shelf then, we have a new but growing set of parts suppliers, nothing like you'd be used to with the Capri though).

First things I'd worry about, diesal lines, tank, pump. ECU and loom stuff (should just be 5 wires from memory) and manifolds/exhaust. All in all though, it'd be a cracker I reckon.

Ooooh, info on this forum isn't free. We require pictures As much as I might like to take the mickey out of Capri's, they still look awesome

My daily obsession atm is thinking about dropping in the S40 engine, can't decide between that or the 360/D5 route. Would mean getting another one of course, the valver is to remain it's reborn angry self But the idea being that the valver becomes a competition car with the diesel becomming a the daily/tow car.

[wilbo8711]

If anyone has 1.7 bits to do the conversion, i'm more than happy to give it a go! e-mail me: frogger8711@gmail.com if you want to talk. or just the 1.7 engine from a 480 to fit in my renault 5. just looking to fiddle at the moment. a diesel volvo 340 would be ideal though as i don't really want to go down the lpg route. getting about 40mpg on average out of my 1.4 340 at the moment but i'm greedy

[TonyTodd]

Cheers! I'll see what I can do re pictures of the big old battle bus (Marv the Volvo) and the Capri.
If I'm going down the oil-burner route for the ford, maybe just easier to slot in an old ford 1.8 diesel intercooler number and plod about in that.
Will have a look at whats available/whats fiscally viable, and keep y'all posted!

so can I understand that it is easy to use Celio's engine insted of B14 without any extra changes? in other words I'll have no need to change gear box?
