    I was reading some forum posts a few weeks ago and noticed that people were selling the LS7 Clutch+flywheel for like $350. Does anyone sell it for that price anymore or is that long gone?

    So I am having some weird issues regarding the electrical system, I replaced the alternator a few months ago and all seemed to work with the exception of one fluke but I wrote that off. I was getting fuel the other day and when I went to start my car back up it just clicked over like a bad...

    Hello, I have a 2006 GTO that broke a valve spring, and the valve dropped into the cylinder. There is a lot of rash on the piston and some damage to the head but it could've been much worse. I brought the head to a machine shop and they said they think it is savable. I'm looking for advice on...

  7. Exhaust
    Hey, I am planning to get a custom catless exhaust system and I am wondering how much harm it would cause my GTO to drive without a tune until I can get an appointment at the local tuning shop. I know it'll throw some check engine codes and a check engine light, I just want to make sure I don't...

    Hello, today I took the heads off of my 2005 gto and while I was cleaning the gasket material I managed to scratch the head. I was wondering if it’s anything to worry about, or should I get it resurfaced. I plan on boosting the car but also keeping my budget down. Is it something I can seal...

    I've been chasing a high oil consumption issue that was slightly improved by replacing valve seals (I did dual springs as well). However my GTO is still consuming roughly 2 quarts every 1000 miles and I believe I have tracked it down to cylinder 7 which has oil all over the spark plug. I checked...
  11. Drivetrain
    I have a 2005 M6 GTO making a little bit above stock HP, when I purchased it there was already a one piece 700 hp driveshaft installed. I broke that one at high speeds due to it not being balanced(I think) and replaced it with a DSS 1000hp single piece with their billet 4 bolt pinion. I still...

  13. LS1/LS2 Engine Tech
    Hello everybody, My name is Marc-Antony. As the title states, I have a 2006 Pontiac GTO. The problem started one day while I was driving and my car wouldn't shift out of any gear. After testing it came down to the Slave Cylinder not working anymore. So I decided to order a Tick Master Cylinder...
