????????? they have galv bodies afaik
engine similar to grale motor but head has smaller valves and ports to give better low down power.
small turbo compared to grale.
get a bleed valve and up fuel pressure abit and have 250bhp
drivetrain is strong
FYI
the Fiat croma, Lancia thema and Saab 9000 all shared the same body just the nose and boot differs.
A better option is the Lancia dedra same 16v turbo motor but smaller body shell.
