Hi All,

I'm also a hungarian Sierra fan and I would need some information as well from you, you Pinto experts Smile

So I have a 24V Cosworth in my Sierra, it works fine but I need more power...

Also I would like to reduce the car's weight, so mainly that is the reason why I want to swap the 24V and and apply a 2 litres pinto engine with turbo (the 2.0 Cosworth is expensive).

I need min 300 hp, but if possible about 400.
My question is how can I retrieve this power from a pinto with turbo, what are the details, probably you have engine in this range...

Thanks in advance,
Luyo

Oh it's very simple, since I have Ford, I would like to run Ford engine.
I don't want to change engine from an other brand...

But it looks fine Smile

That Saab/Ford don´t have 400hp, actually my old sierra where a couple of seconds faster 0-200km/h

Luyo:

Keep the cosworth V6 and mount a turbo on it instead. 1bar will give you 400hp with no trouble at all.

300hp pinto will demand a bit more work.

Thanks Mikael!

So you say that it will be much cheaper if I keep the 24V and mount turbo on it...

In this case do you now any specifications about this project?
So I think I should use 2 turbos, but what kind of turbos? Should I use forged pistons or the stock Mahles will be enough? You say 1 bar, it sounds good but what about compression, should I change the gasket to modify the compression, or some machining on the pistons do more? Or the stock engine will sustain the 1 bar?

So it raises lots of questions and probably I can have them answered also in Hungary but it would be better if you could give me advices about it, as I think hungarian mechanics don't have experience on turbo 24V engines, maybe you do.

I appraciate any help Rolling Eyes

I would recomend one turbo, its cheeper and much cooler with one large turbo than two small ones.
A friend of mine used stock parts and compression but he used a mixture och Ethanol(85%) and gasoline(15%)to get around detonations. To run on gasoline you should lower the compression by using a coppergasket or machining the pistons

Okay Mikael thanks again! Smile

So let me summarize and ask some more questions:

-one big turbo either side is stronger than 2 little? (what about the other side, simple exhaust manifold?)

-which type of turbo do you suggest?

- coppergasket or machined pistons to lower the compression (I think, to get a gasket is much easier but how can I calculate the thickness of the gasket? Is there any program to calculate it? The stock compression ratio of the 24V is 9.7:1 Which compression should I use?

-should I change anything on the ignition?

-will the stock EEC IV computer work with this tuning? (air mass meter, etc...)

- I have an old 2.8 V6 fuel pump, will it carry enough fuel for the injectors?

- are the standard injectors are enough?

-of course I will swap the mt75 to t5 with the clutch system...

Thanks again in advance!

Yes I understand, but you know as it's a V6 engine I have 3 exhaust ports each side. I can collect them to one mounting to the turbo each side. But Mikael said that I should use only 1 turbo, so that would be one side, but what about the other side? That would have been my exact question Wink
Sorry, I'm not a technician...

Holset HX40 or att Garret GT40 would be perfekt for you. Forget all Hybridsturbos (T4/T3) and other small turbos. On that engine you will need a big one. Around 50-60mm on the inlet and 55-65 on the outlet will do just fine.

3mm gasket will do the trick. I haven´t tested cooper gaskets but know that it works for others

For the fuel i would rekomend a aftermarket fuel/ignition system. Standard system will not work so good.

Haltech, Autronic, Vems, Megasquirt and so on. It's expensiv but you will not regret it. Bigger injectors is required. 400cc or bigger to support 400hp, and you will also need two 2.8 fuelpumps.

It´s not cheap to build a engine with twice the power. You could try using extra injectors as i have described in this thread.

And of course you will need to connect all six exhaust to the turbos.

Mikael, xcOOb, thanks again for your help!

Now according to your instructions I 'm starting to understand this Very Happy

I'll try to have a look around about the prices and calculate how much does it cost, also discuss with a mechanic.

First I should buy the turbo, injectors, computer and the other parts then fabricate what I can't purchase.

Just one question Mikael, what did you mean on "Around 50-60mm on the inlet and 55-65 on the outlet will do just fine." ?

It´s the size of the compressor and exhaust wheel on the turbo

Hey Mikael, have you heard something about the 4.0 V6 24V project when the engine block is an Explorer, but the cylinder heads are cosworth 24V? It would be good to mount a turbo on this engine which is 280 ps when it's naturally aspirated. With 1 bar maybe it could produce about 500 ps Smile

It's not bad, but I think for RWD the 400 ps will be absolutely enough...

It's always difficult to estimate cost. Here in sweden 2000 euro will do the trick

Hello from Finland!

Great site you have here and I like your videos too.

But the main reason why I'm posting is that I'm planning on doing a turbo conversion for my Sierra.

That tutorial is great and just something what I have been looking for my budget. But the wiring diagram for extra injectors have gone I see, would it be possible to someone to upload it again? Could be very helpful.

Also how about the ignition timing? It isn't really adjustable in the EEC-IV, so I'm afraid of getting problems with knocking, original timing can be a little too early when there is boost.
In original iS Sierras there is this little 3-pin connector lying under the ignition coil and when you ground those wires you can get the ignition timing modified 2, 4, or 6 degrees later. Have you been using this method or something else, or have it even been required to get the engine run properly?

Thanks

To the left is the pressure switch and to the right is the injector.

Most of all here dont do anything to the ignition timing whit orginal EEC-IV managment.
