Im starting a second build thread for the direction that I want to take my car. I got the car in April and since then it has gone through a crash into a chain link fence from being stupid, to blowing the 7m motor do to a coolant leak that I did not catch.
The 7m motor had 113K miles on it and I managed to update the intercooler and piping, put a ct-57 turbo in and install a map-ecu. The car had a general tune on it and I was able to do 14lbs daily. Never dyno'd it but estimated about 310hp to the wheels since it was a auto and did not have full 3 inch exhaust. Here is what the motor looked like last when it ran.
The coolant leaked forced me to experience all loss of coolant in the motor over a 150 mile trip one morning and I experienced no signs of over heating. (Let's not argue about this it was discussed in another thread) By time I noticed the leak the motor had over heated so much that the motor shut itself off and melted the spark plug boots for 2 & 5 cylinders into the head.
So as a result I pulled the motor to see what really went wrong, and as a result it was a small cut on the water neck hose is what caused the leak. The head was so over heated that it was visible that the intake side was about 1/8'' higher than the exhaust side when you looked at the back of the motor. When the studs were taken out the exhaust side felt they were torqued at 60lbs and the intake probably around 120lbs. The head was originally torqued to 85 when the HG was done at 101K miles. Also it looks like that piston number 2 experienced breaking of one of the piston rings because it is causing a major scratch on the cylinder wall.
