I have a Pure stage 2 DD turbos. The engine has 25k on it and the turbos less. I've had the car 3 years and have driven it less than 3k miles. It smoked only 2x since then, once after changing the plugs and ignition system, and the most recent after the VC change (bc it was leaking and cracked), The first was bc of the vc leak and I believe oil getting in one of the cylinders, the second, well we are talking about that now. I am an amateur and walking blindly in this whole maze of parts and retrofits. I have and will make mistakes and learn from them. There has been no engine neglect or pushing it. My goal is 500 rwhp, nothing more and reliability as this is my daily/family car. Thanks for all chiming in. Wish I could post pics but I don't have the car atm it is in a friends garage and he is swamped, I am stuck at home with kids no daycare/school wife has the only other car she is gone daily oot working.
