2CV 652cc Engines

I'm going to blaspheme here....I like the look of the Citroen 2CV engine. In particular, I watched a video put out by a company called Burton, which, amongst other things, makes crankshaft and piston kits that take the engine up to that magnificent figure of 652cc, which we all know so well.

Forced indoors by the, lethargy induced by a distended belly, long nights and hostile weather conditions, I've been watching a series of videos on this channel.

https://www.youtube.com/playlist?lis...MRIOwzrV8-qBwH

Taking a 2CV from Aberysthwyth to Croatia via an unnecessarily convoluted route, on his own and without any breakdown cover arranged, is the sort of "mad" move that I flatter myself that I will attempt one day. But in the meantime, dipping into these very simple...almost banal (but entertaining ) videos is filling a gap.

But it's the little engine which amazes me most. In no way is Ian holding back. He's at top speed for most of the time, and he's overtaking lorries and taking on mountain passes without seeming to worry about the engine.

I push little Murf quite hard, but the 2CV appears to have a much more balanced design, with those two opposing pistons and a more compact and rigid crankcase.

I'm not losing the faith and could never swap my little Murf for the gangly monstrosity of a 2CV; but I take my hat off, both to Ian and the designer of the 2CV engine.

Re: 2CV 652cc Engines

Early 70ís and 100kms from the Greek border in the country known as Yugoslavia. Canít imagine who the hairy denim clad guy is
Yes that is the engine sitting on the grass.

Re: 2CV 652cc Engines

I wonder if anybody has ever thought about fitting a 'big' 2CV engine into the back of the 500. The Steyr Puch engine (in what is basically a 500 body) is also a 'boxer' twin---just an idle thought!

Re: 2CV 652cc Engines

Italian car with a French engine, eh? You should tie it all together with Lucas wiring and have the world's most challenging vehicle to keep running.

They'll never beat the handling and good looks of this version with the Steyr-Puch though....

Re: 2CV 652cc Engines

I saw a 500 fitted with a 2CV engine at a show in Holland a few years ago, unfortunately I can't find the picture.

I did save this link though which has a few interesting pictures and details about a 652cc Visa engine being fitted into a 500.

Re: 2CV 652cc Engines

I have a 2CV with standard 29HP 602cc twin and I drove it with my family around the world in two years covering 70k miles. So I also thought about fitting an 2CV engine onto my 500. Then I found this on Youtube: https://www.youtube.com/watch?v=TBQkmJg0hJ0

Although I've nevered owned a VISA engined car, I heard they were not the most robust ones among the 2CV series. I would opt for a 602cc engine for reliability. If you do need more power, there are plenty of upgrade options offered by belgium company VGS with with you could get something like 40-50hp or even more.

Re: 2CV 652cc Engines

An old acquaintance did silly miles around Europe on an MZ ETZ250 two stroke motorbike. It did well over 250,000 miles on one engine which eventually got taken out in an accident while still running well.

I asked him how he got such a huge mileage from something that was usually trashed by 50,000. He said the engine is tough but low powered so he just drove it flat out everywhere. He did a lot of dispatch riding but took it all across Europe including Helsinki and Moscow.

Driven slowly, 2 strokes stutter at part load (its the those load reveals that do the damage). Driving it flat out is well within the engine's ability but avoids the chuntering damage.

The 2CV engine is really low powered for its cc capacity so running it flat out does no harm. It's not a stroker so wont have the part load chuntering issues, but keeping it spinning is less stressful on the internals than slogging it. The 40hp Fiat Fire 900 is much the same, foot to the floor does no harm and fuel consumption is still ridiculously good.

Re: 2CV 652cc Engines

The car shown in my picture , from memory , was a 1962 2CV with the original 425cc engine. We were 4 adult males for the 1st 1500 miles and averaged 56mpg then 2 jumped ship for the next 3000 miles raising the overall mpg to just over 70.

Re: 2CV 652cc Engines

I was in Italy about 5 years ago, and taken to a Raduno (car gathering). Somebody cranked a 'bitsa' bike into life, and oh boy, was it noisy! Upon closer inspection it turned out to have a 2CV engine inserted between the frame members--on open exhaust! Sounded good though, a sort of poor mans Beema.

Re: 2CV 652cc Engines

So could a 2CV engine also be put in a Giardiniera.

I bet it could, that's if you could make a gearbox work too.

The next, very useful thing I note, is that both the 2CV and the Steyr-Puch version of the Fiat 500 engine, extremely usefully, have a designed-in oil cooler. Being a positive person, what I take from that is that the Lampredi engine was designed with a much more efficient impeller- assisted, air-cooling system.

Re: 2CV 652cc Engines

The 2CV engine would physically fit into the engine bay---the only real problem would be working out how to then shut the boot area lid down! Giannini, many years ago built (and ran) a flat-4 engine based on 2 Giardiniera engines, with a very short throw crank. One was displayed on the Radbourne Racing stand at one of the "Racing Car" shows---and if you can remember that show, it dates you! Sadly it was not possible to use enough Giardi engine parts to make it financially viable, but it would fit into the back of the 500 saloon.

That sounds like an Alan Millyard conversion. OK when engines are ten-a-penny but not these days when people need to keep the originals running.
