My cousin owns a 2003 Impala LS, and was is looking for advice as to turbo charging it. I know a lot of guys convert from the S/C to a turbo on the Grand Prix GTP/Regal. He has the non-S/C'd 3800, and wants to slap a turbo on it. Where would you recommend looking for parts? Are the trans different from the S/C motor and the N/A motor? Just basically looking for some advice from people who know the 3800. I myself never worked on a 3800 and don't know the parts available for it. I know ZZP works with GTP/Regals, so maybe look there for stuff that might work? Any advice would be great.
