Hey everyone. Just bought a clean one owner G8 GT with the 3.6. Only 105k and completely stock. Plan on driving as a daily for a few years and possibly doing an LS swap. Shouldn't be too difficult considering they optioned them that way. Guessing I would need a lot of GXP parts right? Anyone done this? I know I could just buy one with the V8 but this car was cheap and is a pretty cool car as is. Any input is welcome.
Some years ago there was a kid on here who did it. You may have to search long and hard, but maybe you'll find his thread. What you need is a wrecked GT from which you can pull the entire powertrain, wiring, and controllers.
You sir have a clean one owner G8 base, the GT has a 6.0L V8 (L76) and the GXP has a 6.2L V8 (LS3). I have been thinking about one of these as my next project car though as they are really cheap. If you just want it to run and drive and dont care for it to be a DD it will be super easy to do.
12-18 months WTF? I rewired my entire car in like 2 weeks. 12-18 months I had like 4 different turbo kits made and swapped trans three times lol
He's talking about swapping out the V6 for a V8. Little more complicated to change an engine than some wiring or adding a turbo. You can't even swap a module in a late model GM without getting it programmed and some can't be programmed at all if the VIN doesn't match.

Its not that hard... engine swap takes a couple hours. Use ECM from V8 you can change VIN in HPtuners, keep moving, more working less excuses!
Same people thought a manual swap was hard, it takes 3 hours. Keep BCM working and run Holley for ECM, its wiring. Its only as hard as you make it.
