It seems that all fiat forum members are going turbo crazy....i ll post the same answer i gave to another fiat forum member..!!

"Good morning from greece...

It seems that you are very lucky cause there is the coupe engine which is very similar to the scumachers'..!!

my english in mechanical terms is not very good so you just have to bare with it..!

You are going to take the intake, outake,headgasket and exhaust from the coupe 20v engine and the pistons will fit as well...!!The pistons are capable of withstanding up to 1.4bar (don't know the psi conversion)..Anyway i don't think you are going to need more power...At 1.4bar the estimated power is over 400ps so i think it is enough..!!..You can also take the injectors from a coupe, to provide efficient gas..One other trick is to increase the gus pressure..Normally this is set to 3.5bar by the factory..Now under the backseats is the gas pump...You can take that out and you will see that there is a small metal thing that controls the flow of the gas...You need to bend that a little so that the gas pressure is stable at 4.2bar...There is a chance that the coupe gas pump will fit as well but i don't know that...

The tricky parts are the electronics and ecu...I know there is a guy from holland (MANTENOS RACING) that all he needs is the ecu so that he can programme it to run on schumi with coupe settings..This will take care of the ecu...Basicallly you need to find a good ecu programmer, to cheat the map/maf sensor cause it is set to read up to 1bar (atm. pressure)...Since the turbo will produce up to +1.4bar (1+1.4=2.4) you need to find someone to "cheat,bypass" that, and feed the system, with a stable reading of under 1bar (atm . pressure) cause the system will go in safe mod all the time...

If you don't want to program the ecu you can fit 10 cm away of the intake onto the intake pipe a 6th injector from a ford sierra (green) which has a capacity of spraying 500cc per min. with a mini ecu of its own, which is linked directly to the pressure and sprays accordind to that..I wouldn't suggest that cause you don't change the avance with that...Only by programming the ecu will do that..!!!

feel free to contact us whenever you want...Good luck with the project...

i insist to find a guy that will handle with all the electronis BEFORE you start ripping off things from a coupe..!!!
