Technical 1.2 16v turbo project
What is your budget?
Why complicate when you have 1.4 16 t-jet engine

Yes.. I dunno why you want to turbo-charge a 1.2. You have 75 or 80bhp ... you'll spend €2000 and you'll end up with 100bhp. It would be easier and maybe more interesting to just fit a 100bhp 1.4 engine from a Panda 100.

Well.. I admire your optimism.... 
Yes...120-130bhp is easy. Preventing the engine from blowing up after 5000 kms is slightly less easy.
A crankshaft is designed for a certain amount of BHP... generally cranks are moody and try to escape from the engine block if you make them work more than 30% harder than they were designed to. So 100bhp is okay using standard parts. If you want more power you will need to buy new components.
Generally for a big BHP turbo install you will need;
1) The turbo kit (including an intercooler)
2) New/lower compression ratio pistons (since it'll be a lot hotter in the combustion chamber... and Fiat's pistons were designed for atmo' and 80bhp remember).
3) A stronger/reinforced and balanced crank since you insist on 130bhp...
4) Possibly stronger con-rods (but let's say the standard ones can absorb 130bhp for now)
5) Possibly bigger injectors (since all that extra air going in needs fuel to make power.... and the standard injectors are only designed to deliver enough fuel for an 80bhp engine).
6) Your 8 valves might be big enough to flow all that charge.. but the inlet tracts will be too small... so bigger inlet ports (machined from standard). Possibly new valves and harder valve seats later on.
7) Remapped ECU so that everything works together - don't underestimate what a PITA this will be to get the fuelling and timing optimized.
If you have a car accessories shop and mechanics who know what they're doing it's definitely an interesting proposition.. but if you just want a project that's going to give you an interesting mod' but a car you can then still use every day without worrying about what the fuel map is doing... just transplant an existing engine/combo'.

1.4 16v has 120HP with 0.9 bar pressure.
So actualy i made this build, running a turbo + intercoler on my 1.2 fiat stilo, but as soon the turbo boosts, goes on limp pode and cut's the throttle
Already tried to use a zener diode between pin 1 and pin 4 on the map sensor, with no success, any ideas without change the stock ECU?

Keep the stock ECU, revert it to standard engine configuration, sell it, but something more powerful/faster, or, spend a fortune trying to get it to run right.
