So what is the best methods to turbo charge your stilo 2.4 abarth. I emailed some body about this topic and they gave me a extensive list i thought i would share it with you all.

It is possible to turbocharge and actually it is quite a lot easier to do because you can pinch half the parts you need off a Fiat Coupe 20V Turbo as they are the same engine more or less.
It depends what your power objective is with how much it will cost as well.
The best place to speak to is Barbz @ Torque Italia (www.torqueitalia.com) - he has the expertise to do the job.
You can take the following off the 20V Turbo engine
- Intake manifold (the VIS manifold is unsuitable for turbocharging) and plenum chamber
- Exhaust manifold
- Turbocharger (but you will need to clip the turbine wheel as it will overspeed in a 2.4 engine) good for about 270BHP max
- Exhaust downpipe
- Head gasket, head studs
- Turbo camshafts
- Sump with turbo oil feed return
- Injectors (good for up to about 330BHP) and fuel rail possibly
You will need
- Forged pistons if you want more than 220BHP probably. The std pistons are probably ok up to 220BHP, but you will have to run very low boost because of the compression ratio. With the 20VT head gasket you can lower the compression ratio of the engine to about 9.5:1 but that is still quite high for a turbo engine.
- High temp/sodium filled exhaust valves. You might be better fitting a stock 20V Turbo head on instead - they're interchangeable
- Uprated fuel pump. You may need to fit a return feed and swirl pot in-tank as well
- ECU compatible 2.5 or 3 bar map sensor
- SOmeone willing to do an OBDII map for your car
- Intercooler and piping
- Intake filter and induction pipe
- Modified exhaust (to fit onto the exhaust downpipe from the turbo)
You may well need a couple of slimline fans so there is space to fit the turbo off the exhaust manifold
You also need an oil feed for the turbo, so will have to get that from somewhere. Std turbo cars ususally have the block drilled to provide it. You will need to look at what you can do on the gearbox and clutch front whether to go back to a manual setup
You will not have to change the conrods as long as you don't go above about 350BHP.
If you want to do a very mild turbocharging you could probably get away with a lot less stuff, but you would be limited to about 220BHP max for things like injectors, fuel pump etc.
By the way Forza tuning have quite a dubious reputation, so beware.

anybody have any thing to add to this list?

well i emailed the fella he mentioned.

Hi
Your kind of limited on what you can get from a normally aspirated engine. But C&B fast road cams are available for this model and with some head work we may see close to the figure you want.
Or you can be more radical and go Turbo, but must warn you that it'll start getting costly to go that route.
Be very interesting project though with 450bhp.

Unfortunately, it is a 10k conversion.

bummer considering i didnt want to spend that mush that kinda pissed on my chips abit.. so any body whos a stilo veteran willing help me mod a 2.4 stilo into a beast, please stand up, please stand up
