The "target" Callaway is my 1986 GTV6 and yes there were custom SS exhaust manifolds fabricated by Reeves Callaway for these twin turbo charged production Alfas. Only 2 or so Milanos and around 35 GTV6's were produced by Reeves Callaway for Alfa Romeo making these 2.5L V6 high performance mid 1980 Alfa's very special.
Any updates? Spruell converted two Milanos and they were dark blue like this one.
Indeed. I'd be interested in the details too. I understand there is another thread on the forums with details about the Callaway implementation. I am wondering what changes were made to the L-Jet to run the turbo set up.
Of course these days it would probably be simple with a custom ECU.
