    For those that did the 6l90 swap on the g8, did you guys use the 6l90e out of a ctsv or zl1? Does it even matter? I have a ctsv transmission I got for 600 dollars in great conditions. I was told that it would not work with the g8 though. That the transmission has to come from a zl1. Any input...
  2. G8 GT Talk (V8)
    Looked at this g8 today and it was super clean besides a couple of things. Newer headers into custom exhaust, power steering seems to be going out, steering wheel vibrates and shakes around 45 mph. Not too worried about exhaust because i was going to get an exhaust anyways but the pipes are...

  7. G8 GT Talk (V8)
    Hey everyone. I bought another G8! This time its a 2008 GT. I found it on FB. A small dealer bought it from an auction not running, engine half disassembled. He was going to sell it to a junk yard if no one took it because he doesn't have time for it, so I figured I try and save it from death...
  8. V8 Engine Tech (L76/LS3)
    Car is in storage right now, but when I get it back in the spring I plan to update my dyno tune a bit. After getting the car tuned, I was surprised that the cam didn't lope as much compared to others with the same cam. My initial though is that maybe its idling too high (around 650-700 I think)...
