need 75 Evolution and 1.8 turbo info

["cpapadop@xxxxxxxxxxxxxxxxxx" <cpapadop@xxxxxxxxxxxxxxxxxx>]

Hi people,
         i'm looking for some help with information from Alfa's turbo 75
homologation cars. We've been running the engine out of one of these in
group A form for the last 5 years in our GTV racecar, but it let go in the
six hour last week, and so now to consider the options, we have a brand
new 1.8 turbo engine from a 75 Evolution, sealed from the factory, but
can't find it's  stats such as compression ratio, standard power output,
maximum feasible boost, and such things, so before we go about getting it
race ready, we would like to know abit about how it would run. So in a
nutshell, could someone please help me with some figures from the Factory
75 Evoluzione Turbo's from 1987, or subsequent experience with turbo 1.8
engines, specifically boost, compression ratio, and problems with
detonation and cooling. 
Thanks in advance,
