General diesel cinq thoughts

[clock34]

a 1.4 stroke of 84mm compared to diesel 82mm would move the pistons 2mm lower than on the 1.4 16v???? or would the block be shaved down more so it would be the same???

also 1.3 entire block weighs in at 130kg's

but with the petrol head do you think it would actually be more?

the 1.3 multi jet is only 1248cc, is not really a 1.3

just to quickly skip back to reality its gonna be one hell of a shopping list for you
:new tank
:fuel pump
:fuel lines
:aftermarket ecu or others
:custom exhaust and cat
:custom mounts
oss custom driveshafts maybe ??
and many more

that's if you went all out diesel, you have to remember this with the new 1.3 multijet you wont be able to run in on any after market currently out as the engine has 12 injectors that cut in and out when the engine needs power under certain levels of load


if you went for the hybrid engine there would be a few new parts but alot could be modified to suite

What about getting a rolled car and swapping everything over?

Silly amount of work, doable but bedlam may result.

I hate to say it, but just buy a 1.4D Aygo/107/C1 instead.

i was thinking of stayign petrol so make a 16v loom for the 1.4 then wack the 1.9 diesel block on. but i think the valves would be too small. but the 1248 diesel block if can be fitted to say a 1.28v head or a 1368 8v head then turbo's would have a low compresion due to the shorter stroke (could rev higher too???) pistons capable of taking more pressure due to loads of diesel engines. and a steel crank again due to pressure so would you not have a stronger engine????

Ermm if it is the fire block, then nope just use cinq shaft and mounts .

that's the good attitude that made some thing possible "too hard why bother"

the 1.9 diesel block is just soooo different and would need a different gearbox

the 1.3 block should mate up with any of the normal 5 speeds on the fire range


the 1.3 has pretty small ports but very good flowing ones (and there isn't fuel vapour in them)

without the engines in-front of me i couldn't say if you could use the 1.4 petrol pistons in the 1.4 petrol block with the 1.3 diesel rods and crank due to the fact the lengths of the crank throw rod length and the location of the pin on the piston could be different and when put together could end up with an odd stroke

so you might end up wit ha high compression or low compression engine

i don't think the valves would be a great restriction on the engine like that

dont get me started on small french cars. theyre all the same they fight you at every turn and turn simple mechanics into a nightmare

Be fair, I am finally dragging myself through University at 27.

And Centos don't have awkward jobs (mainly where access is involved)
Also it might be Toyota leading, not PSA Peugeot Citroen (not sure either way).

Yes, I would like to see a diesel Cinq or Sei, especially with newer, nicer sounding (and smelling!) diesel engines and the freakishly high MPG something that light would return if tuned for economy instead of performance, but it's still a huge undertaking.

Also, add extra sound proofing to that list.

its just french cars i have a real hatred for them although ill admit theyre better nowdays but old cars :bang: only good thing about them was ragability

 

[craigb244]

trust me... without even seeing a diesel engine with the same block design as the fire engine it WILL be totally different.

First of... the crank journals will me HUGE compared to a petrol engine. even if you decided to use the block and rods you will find that the gudgeon pins will be HUGE. and rods will will be mahoooooosive.

then the head from a petrol wont fit because the block will have more and/or much much larger head bolts.

think of it this way...

Diesel cylinder pressure : 200+ bar
Petrol : 10ish bar

 

[clock34]

see i was thinking that about the head bolts. but there are companies that could sort a plug type sytem with reverse screw.

tbh dont think anyone is ever going to do it but i honestly think petroldiesel engine is possible one day lol

 

[ycming]

Hm use head studs ? APC might make them ? Yeah don't think anyone will do this

if i had the money i would buy a 1.3 njet engine and a 1242 and then pull them apart and see what happens, but alass i dont so i cant but i pray to god someone on here grows a pair and has the spare readies to give it a go cos personally i think it would go one of 2 ways

1:- be way more powerful than anyone thought
2:- not work and pull itself to bit on first fire up

I'd put money on it being the later.

If you're gonna use the diesel block, use the whole thing rather than messing with the petrol head. TBH unless you go for a mega boost engine its a waste as diesel engines aren't designed to rev above 5K. Compare that to petrol ones which are perfectly ok at 7K. Thats assuming you can get it to run properly at all.

And that's all before you start considering that you've probably added 50-100kg to the front of the car. Something a large car can tolerate, but a cinq would probably go all understeery, not fun.

Better off getting the 1.2 16V engine strengthened properly to run mega boost, far more rewarding in every way.

 

[craigb244]

worth spending the money on something better... something like getting the top half of the 16valve head redesigned to allow the use of shims to get rid of the HORIFFIC hydraulic tappets.

 

[jaydr]

so would the 1.3 multijet be a candidate for a relatively straight swap?

 

[dronenrs]

probably the easiest of the hard ones

 

[jaydr]

if it is an option then id be tempted :yum: i bet it could be tuned to an adequate level for the cinq
