Re: Turbo
I would say, save your time and effort... It'll have to be a one-off prototype or altered aftermarket kit that is re-manufactured to work with the 112 engine and electronics... And you'll be the first guinea pig and about $10,000 lighter...
Go purchase a Pontiac Solstice GXP / Z0K with full race suspension, aero kit & aftermarket turbo, in the $30,000 range, you'll save yourself a lot of time and money...
