Has anyone tried to fit an 20v turbo engine in a 131?
I want to try this but i was wondering if someone had done this, and how much work it is?

Imagine that in a S1. You'd need some serious brake and suspension modifications Grin Grin Grin For starters.

Can't find the picture of that 20V engine yet. I know it is in an Alitalia replica. Perhaps somebody can help?

I could be missing the point here but isn't the 20V 2000 CC engine the straight 5 engine?  Not the FIAT TC that we know and love?

Yep, they're still a twin cam, just a modern more powerful version.

Now i really wonder why someone would make such an exhaust header. The best way is a direct flow straight from the head. Horizontal as to say.
Why first go up and then with a big curve down? Could anybody explain this to me?

Tanks for all input.
As I said before I already built me an 8v turbo engine, and today I found the cylinder head   Grin
The reason I want to put an 20v turbo engine in a 131 is ofcorse the power and that I want to do something new. The reason that I am asking is because the 20v turbo is a rare car in Norway and they cost 12000-20000 euro  Tongue
So I must import one from the UK.

Hi Mike
The exhaust and general system on a turbo is a case of trying to capture and transfer pressure.  The exhaust behaves differently to a normally aspirated car.  Add the massive heat generated in a turbo and it makes sense to lift it to the location on the green car.
The exhaust pipes are as short as possible into the turbo.  Once the exhaust passes through the turbo, much of the pressure has been consumed and the wide exit pipe works well when it takes a smooth route away from the turbo.
This installation also makes sense with regard to heat.  By wrapping the manifold and turbo housing you help to contain the energy and achieve better response.
The other benefit is that the compressor housing can be kept in the coller airflow area and provide cooler air to the inlet.  This gives better power.
Overall it's all good.  It's a neat installation.

Not only is it easy to service, it looks great under the bonnet.

With the potential power from this installation, how does the owner contain it and keep the car pointing forward?Huh

Thanks
Duncan
