When I bought the car it was like this:

Some years later..

Two weeks ago I took it to the power bank
[Image: ee863ecf9d21be98bb7f70c9463c9db8o.jpg]

But the results were not very good and the graph was ugly...

The pump didn´t let the injection map as it should and the third injector was damaged but.. news are in comming Big Grin

Now I also thought about changing or hybridizing turbo but I don´t know what to do, the space is very small.. 

English are the experts in these things so I'm all ears



Sorry if my English is bad I have to improve it

Your english is fine dont worry. As for the turbo a lot of people use the gt2052s off the landrovers and mercedes but you have to make them fit. Ive known a few people who have run hybrids over here. Seems to give a power increase just not as much as fitting a bigger turbo. im not sure about the science behind why though. I think hybrids still suffer from high manifold pressures.

What a spec! Fair play, you've obviously put a lot of time and effort into this. Who has done your mapping for you? From that picture of the smoke and the dyno graph i would say that is your main problem - a good map, intercooler and exhaust should be enough to reach your target. With the specification you have and a better turbo you should be able to achieve 170-180. I am assuming the MAF sensor is working properly..?

My map has been made by a local business "Spark Load". Now i´m repairing the pump and the injectors for everything work fine. 
To mount a turbo better I do not know what to put .. any help? I´m thinking that hybrydate the original is the best option because there isn´t a lot of space...

Sone people put gt2052s down the back on the 306s. Came on mercs and landrovers. Not sure what the soace is down the back on a 206, if youre concerned go hybrid but its lots of money but less hassle. Ive persnally never driven one but apprently hybrids suffer from back pressure issues as the exhaust housing is quite small on standard turbo

Ok, in which case i'd suggest contacting hdi-tuning for a new map, you might find that makes a lot of difference.

As above with the turbo - using the standard hotside to make a hybrid will cause you problems with back-pressure. You'll be better off fitting something bigger altogether, if you can't fit it down the back then relocate it over the gearbox.

Hi everyone, I bring bad news.
The engine is probably broken...

I am thinking of doing swap to 2.2 but I do not know if it will be too hard (4hx engine) or if you can in the original block rhy put a 16v rhr engine butt.

What do you think the best option ??

On the other hand the easiest option is to leave the factory engine and fatten it until leaving something good and reliable.

I do not know what to do

Hello everyone, sorry for so long without updating.
In the end it was nothing serious. Only a rocker that broke. At this time I had to prepare the car for the technical inspection that is here to pass every year and is already surpassed.
Now I'm popping up another problem that is that the car in stopped and starting made quite white smoke I suppose it will be cause of an injector that was damaged but I have to check.

On the other hand I would like to continue to evolve the device and put things like an RC bridge with disc brakes or put turbo of variable geometry among other things but I do not know if I put a 2056 2060 or 2256, what do you recommend ??
Is it very difficult to install a variable geometry ?? I know that you have to wire several pins of the switchboard but I will look for whoever does it.

Does the smoke smell of fuel and burn your eyes/nose? If not, it's more likely oil smoke from a dead turbo.

It isn't much more difficult than fitting any other non-standard turbo.

Hi guys, I tell you about the little project.

The last problem I commented on was the injectors, I did not manage to go around like this for a while and I broke a rocker from the cylinder head.
As the car had already more than 300,000 km I decided to put an engine that I found with 76,000 km and do things well.
I had to hybridize the turbo, I put new injectors with larger cummis nozzles and I had to hybridize the r70 pump and they made me a r85.
After a little more than a month without a car, he finally left the shop and turned on the lights.
Now this week I will get it to make the electronics to measure and to implement multimapa with 2 curves of power.
As soon as I have news I will teach you

Whats with the injectors then? Never seen ir heard of cummins nozzles fitted to them. Are they the correct flow rate then?

stock injector with DSLA 143P970 - 0433175271 reference nozzles. Tested along 5 years on a rally car , and one street car Smile
Its difficult to calibrate soi - pressure - aperture time maps, but not imposible.

this nozzles flow muuuuch more fuel, but its not good option for low-mid rev's. This is only usable on stage3 , and need good turbo.

im runing 95-100mm3 and i think its reasonable limit for stock connecting rod and pistons. I have broken 2 engines going over 100mm3 limit.

2.2 4hx fuel pump , stock injectors with this nozzles, and you have no problem to make window on engine block.

Those DSLA143P970 are from an Iveco Eurocargo - they're not correct for the 8v engines. Will always smoke and never run correctly as at certain SOI angles with any amount of fuel being injected, half the cone doesn't actually hit the combustion bowl, they will fit the 16v engines however.

If you start injecting really large amounts of fuel and temps are high, I'd expect to see burnt pistons after a while.

As others have found many years ago, simply increasing the needle lift of the stock injectors will net a good gain in fuel flow alone.

yes, car smokes a bit when its cold... and never have found solution for this  Dodgy  Why you know that "half the cone doesn't actually hit the combustion bowl" ??  Huh

please, need good explanation for this because i dont undestand .
And can you give more info about updating injector internals? what they do when remakes injectors?

The plane angle is because the injector in an 8v HDi does not sit upright - imagine the injector nozzle in a 16v configuration, they are angled at 0* to the piston bowl like so:

[Image: gtp_138_10_102808_f005.png]

The 8v HDi is angled to avoid the camshaft - since the camshaft is in the centre of the bores, the injector must be angled to allow the nozzle to reach the centre of the bore, so the nozzle must have a "plane" angle - this is the same type of nozzle with a 25* plane angle:

[Image: gtp_138_10_102808_f004.png]

Hope that kinda makes sense - this is why the spray does not hit the combustion bowl at certain SOI angles, you will never fix the smoke because the angle is simply wrong and is not able to combust in the right area correctly.

Hello everyone, I have been absent for a while in this forum and I see that it has had activity. Now I update with news.
The last thing that was done was to put a 70,000km engine that was a failure.
That engine was never able to be fine and after 2 weeks preparing the electronics with the two power maps one day without logical explanation, it broke the engine.

After this, prepare the original engine, leaving as new as possible, and become riding again. Now the car is working quite well but still has problems of shortness of breath and the only solution I can think of is a larger turbo or port the stock.

Maybe @Ruan can help me. Right now I'm still with OEM injectors but I have good ones at home for the moment to assemble them.

Gasoil pump I have an r70 hybridized to r85 so pressure problems should not have.

As they say around there I was having breakage problems with valve valances. To solve them what would I have to do? Put harder valve springs? Any reference?

When I get home I put some pictures of how it is mounted now that I am now from the university computer and photos always look good XD

The project continues. Right now I'm working on a intake based on the gr.a

[Image: 27336248_1980398012281804_81810756795634...e=5B145944]

As soon as I have it finished I will update with more photos. The car now goes pretty well with about 170hp. It has two changeable power maps at any time with a simple combination of pedals.


The car looks pretty good today but I'm thinking of putting 16-inch wheels that at 15 I'm starting to notice traction losses

[Image: 24837599_2087344514831392_73267376859686...e=5B15E517]


On the other hand I got an engine in which I want to prepare a new project and mount 16V cylinder head that what I see in some good projects in this forum is highly recommended. Let's see what comes out of here. For now in this end with the intake, change camshaft, redo escape line in 2.5 "and surely put a larger turbo, I'm thinking of a garret 2256v
