  1. Drivetrain Tech
    Okay so, Weird thing happened to me twice now. My car (3.6l/5L40) while cruising down the highway at 110 (kmph) shifts into park for a couple seconds then the car resumes. The physical shifter itself is in drive. I hadn’t touched it. Just the digital display reads out P (for park) and it kicks...
  2. PCM Tuning / Dyno Results
    Just wondering what types of online tunes are still available looking to get headers and I think extending the O2 sensors might be a little out of my reach.

    Alright I don’t really know where to start but basically my car has a rough idle that start a few months ago has really gotten worse or change at all.

  4. V6 Engine Tech (LY7)
    Just got another G8 (V6), everything works fine. Runs and drives perfect except sometimes when I come to a stop my engine dies out and stalls. It starts right back up with no issues and drives like nothing happened. The problem occurs intermittently so sometimes I’ll come to a stop and it’ll be...

  6. V6 Engine Tech (LY7)
    I recently had a pretty big problem with my G8. I blew a coolant hose and the car got pretty hot. I changed the coolant hose and ECT sensor and I burped it. While it was being burped it was jacked up and I recently bought some RP to do an oil change (was running Castrol Edge). So I decided to do...

  8. Newbie/Introduction Forum
    Hey guys, I'm from Australia. Even though I don't own a G6, just thought I'd pop over and show some pics of my car. It's a 3.6l supercharged motor. Tuning is still progressing, hoping to see 260rwkw, or more. No idea what she's making atm. Will be posting more information soon, as cams and...
  9. G8 Talk (V6)
    I noticed there was not a thread for the NEW v6 owners. Just thought I'd start one and make some kind of introduction. I just bought my G8 last week. I remember all through high school I said I wanted a G8, the closest thing I came to was a G6 due to money. Now I finally have my G8 and even...

    Hello, I am still pretty new and own a 08 G8 v6. Like the rest or most of the people who own the v6 version are looking for modifications to enhance their G8 v6. I work at a autopart store I rather manage it so, I am proposing a reasearch and possible production of headers and possible turbo...
  13. G8 Talk (V6)
    Hello everyone, I created this thread so V6 owners that are tired of getting laughed at and stomped on by V8 owners :slap: can learn there is still hope. Anyone with a V6 that modded their car for performance is welcome to reply on how they made their build. If you can, tell us the what, how...
  14. V6 Engine Tech (LY7)
    Finally got this kit in. Since there hasn't been much info on it I figured I would do a show and tell. Off the back I'm pretty damn impressed. It's a full kit which includes; 2 secondary chains, 1 primary chain, 2 intermediate gears, 1 crank gear, 2 sets secondary tensioner and brackets, and...
