Hi everyone, I own a 2002 Pontiac Grand Prix SE and I want to swap out the 3.1L LG6 V6 (mine says 3100 SFI V6. Not sure if they're the same engine or not) with a 3.8L 3800 Series 2. I want to know If I should get the 3.8L S/C because I plan on putting a turbocharger in it or if I should just get the 3.8L with no S/C? My main goal is to up the engine to a 3.8L because many of my friends say the 3.1L wouldn't be able to handle a turbo (they mostly deal with Civics) and I want to up my 4-speed auto to a 5 or 6 speed auto but I can't find out what 5 or 6 speed automatic transmissions match up with the 3.8L engines. Which leads to my main question, what type of 5 or 6 speed trannys can I use with the 3.8 that won't potentially get ruined and cost me in end? (If I can even up my tranny to a 5 or 6 speed.) Please let me know my fellow Pontiac drivers and mechanics.
P.S. I know very little about cars and I'm learning on the way.
