I had a 300bhp Fiat Coupe Turbo (heavily tuned). It handled the power very well. Even an instructor who drove it around Mallory commented how well it handled the extra horses. As the GTV is basically the same as a Coupe at the front (and much more advanced at the rear) I think a turbo conversion would work well. I'm thinking the conversion would be an unbelievably expensive and complicated job though.

You can definitely turbo your GTV 3.0.
Don’t touché the motor just ad a turbo and intercooler with 0.4bar boost you will be making more than 300whp reliably. A T3T4 hybrid turbo with external waste gate will be perfect.
Don’t change the stock ECU just ad a standalone unit with injector for fueling.
Not sure about shipping but we can help you with a flange to mount the turbo pictures of the pipes and the stand alone management with wiring and instructions how to connect it as well as a base map which will be fine although a bit riche.
1000cc bosch injector, turbo, waste gate, intercooler and pipes will be more effective to source on jour side.

price list would be around the following

Turbo £250 Ebay?
Mounting £180 Alfa (the one off the 2.0 v6 turbo if it fits)
Intercooler £100.
oil pipe work £75.
Intercooler pipe work £75
Unichip piggyback ECU £470 excluding RR time.
dump valve £90
Custom exhaust pipe work £250
plus injectors and other bits of work so in total about £2k...

But thats just my thoughts.

this sounds good bud thing is its getting the parts and knowing some one to build this set up and install it etc time i have done that then maybe a super charger but auto delt dont sound that bad but turboing the alfa is a very nice idea and i think i getting a nice rebate so its all going on my alfa :)

Depending on the rubber you are using.
With a Q2 and 225’s you should do the ¼ mile in the low 13’s high 12’s with the top speed limited by your gearing so with a GTV 3.0 it will be more than 270km/h.

The 2.0 with a turbo will be faster than a stock GTA

With what you mentioned plus exhaust and higher CR you should be on par with a 3.2.
Go the turbo rout and get it over with +\- 300whp and you do not even touché the engine internals and low boost.
If you get adventurous and turn the boost to 0.7bar which it will easily take you should be making in the region of 350whp.

Whats the best/cheapest way to get the compression down to fit a turbo and anyone know what the standard CR of the V6 is?

Decompression plate and two gaskets? Machining the combustion chamber or changing the crank stroke? or dished pistons?
All seem like they would be a bit pricey

Do not change the cr just put the turbo on
Stock is 10 on the 3.0 and a bit more on the 2.5 and 3.2.
We are boosting the 156 2.5 0.6bar with stock cr and management just a 1000cc injecto for fueling
