Ford Sierra 2.0 DOHC Turbo.

Hello Skogenracing and all Ford fans our name's are Dennis Aretz and Loek Aretz from Holland.
For about one year ago me and my dad begin whit track day racing whit our Ford Sierra 2.0 EFi DOHC and in that period we already modified the car a bit.
We have removed the interior and places two race seat units. We have a open k&n filter and have some smaller wheels for some more acceleration and open the gril for some more cool air.
This week we have raise gas pressure increases and we have a Cosworth exhaust now
For next week there will be a track day planned so we can see if all the hard work paid off.
But there is always need more power.
Now we wand to build a budget turbo on the Sierra 2.0 so let's get started.

Kind regards,

Dennis and Loek from Holland.

So we buy a turbocharger from a Volvo 940 2.3 T4 for the Sierra, Yes !

And also get some exhaust flange and some gaskets.

And some connectors for the oil lines and oil sensor.
Only the screw-thread is poor so we have to find a new one for that.

And we also have a pair of new Siemens 290cc injectors for some more fuel !

And then my dad was started to building up the turbo manifold of stainless steel and welding kit with co2. A big job.

So my poor dad welding all day for this result, we are very happy with the end result of the manifold.

End here is the Volvo 2.4 T4 turbo fit on the Ford Sierra 2.0 DOHC engine.
We have some work to do on this but the manifold what a big step forward today.

We have a little luck last week that we can buy a second spare engine for less money.

very good.

Okay build up some cooling pipes for the water hoses.
The turbo is water cooled so that is done now.

Close up...

Some new pards for the turbo project...
Turbo booster controller and some hoses.

Thanks Thierry.

news ?

Soon more Thierry, the turbo is running and it is running wel. Last details and test will be come soon.

Nice job! Most fun for the money

The turbo is running and it is running fast !
Only around 2000 rpm he holds in a bit, don't know where to search, anyone knows ? Tips are welcome !
When we give it full throttle there is no problem but if we give him metered gas hold briefly and then he shoots just out there.

We drive a Volvo 940 2.3 Turbo T4 with now 0.4 bar still retains the standard injectors and no intercooler. we just simply need more gasoline?
We don't have ride it on the track but on the street it feels real powerful and we have good hope for track conditions because the wheels don't spin to quick.





Also, a new steering wheel and installed new racing belts.
