Pinto Turbo Conversion - Howto

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.

Thanks! But the problem is that they are written in Swedish and I can't really tell what are them... I also found this from the Swedish tutorial:

Again I have the same problem, I don't understand Swedish. Some bits I understand but not the whole diagram.

Very fast done

Big thanks!

I'm not still sure what that pressure switch is or from where to get it.

Its to start the injectors at a special pressure eg 0,3bar och 0,5bar. U can get it from a old saab turbo our use a industrial one. The simpliest is to use the orginal oil pressure sender. U have to mount it so that it has boat pressure and vacum eg in the intake mainifold...
Im sure u can find more information on this if u search.

Yeah I just did some searching... I know pretty much how it is called in Finnish "painekytkin". Adjustable would be nice, but it is hard to find a one what is designed to low enough pressures.

With the oil pressure sender you mean Sierra's original one? Does anyone know in what pressure it triggers the injectors?

Around 0.2-0.3bar

Ok, that sounds just perfect.

that is imposible to buy sierra with turbo from skogenracing!? how much?

Think no one have anything for sale, look in "köp o sälj" section on the forum..

ok! tnx

Oh btw one more, when using the Sierra's oil pressure sensor / pressure switch, is that relay nc (normally closed) or no (normally open)?

My understanding on electrics is quite low and my mate just give this question for me.

The oil pressuare sensor is closed when its in "standbye" and the circuit is opened when it have pressuare

So nc relay then?

hi, i have sierra pinto 2.0 and want to blow it up to 0.8 bar, is it okay with stock engine? standart compression ratio and pistons. can i use stock ecu?
what injectors should i use for this pressure?

thank u.

PS great site )

Yes its ok, but the engine needs more fuel. Standard Ecu and some extra injectors driven by a oilpressure switch works. Or 350cc injectors and a biggar and modified air mass sensor

can u tell me more about modificating mass air sensor?

Its also called Air Flow Meter ( AFM ) Use a bigger one or modify the "house" to be bigger. But i think the best way is to use aftermarket injection system as megasquirt or haltec ect...

i was thinking that stock maf willn't give right signal cause too high air flow. i think i will use ecu j5sport its famous in russia cost 320$ and it's easy to program it using lambda(broadband? don't know how it ll in english).

Hello everybody!

I´m from Estonia and my Sierra iS wants to go faster too!
The whole idea is damn simple, thanks for sharing it!

I have one question: Why theres have to be a relay between battery and injectors? And may there be any 4-pin relay, I can find, or are the numbers on pins important? (Im not that good in electronics)

Still, one question more: can anyone suggest, which A/R turbo would be the best to install on a sierra?

The idea is to ease the current flow through the pressure sensor

most relay are 4-pin, but to use a oil pressure sensor you need a 5-pin relay.

We don´t think in A/R. For a simple turbo conversion you can take any turbo from a ordenary car that has the same displacement.

Ok, thats clear now.

But what about the knocking?

Actually it would be quite easy to adjust the timing with another pressure switch.

Or using 98E gasoline I dont have to worry about it?

Another question, can the spark plugs may be original or I have to use "colder" plugs?

You can adjust the ignition on the distributor, the only problem is that you adjust the whole curve, but it´s such a small adjustment så it dont matter that much

I haven´t four K-Jetronic injectors, but I do have BMW 2.0 injectors, may I put those too, or they have to be exactly the cold start injectors from Sierra (because their flow rate etc?)

I suppose, you ment these cold start injectors just because they are very easy to mount on the manifold?

can u show me more photos about mounting extra injectors plz.

Hello,

I see your videos and website and have my Ford Sierra 2.0 DOHC converted to turbo.

The oil supply is connected to the oil contact but now the little engine lubrication oil is only 1 bar and that would be around 3 bar should be.

Do you have this problem and how you solve it? The pictures of the project follow.
