At that point I was tired of working on the project. The fabricating and build was fun, but not chasing oil leaks and tuning. I took the car to a friend’s shop in San Marcos KB Motorsports to have the oil leak addressed and a clutch issue as well. They were able to fix the oil leak but not the clutch issue as it most likely was a pressure plate defect problem.
I made an appointment with Chris at Turbo Kraft to take it to him for dyno tuning last Wednesday. I showed up first thing Wednesday morning with the car and ready for tuning in hoping they could also figure out what the clutch problem was.
Mike at Turbo Kraft dove right into the car to confirm all of my build/ installation was ok. Then he went into the trouble shooting of why the car was running on 1,2,3 cylinders. The crew at Turbo Kraft worked so fast, accurately and efficient my head was spinning. In a very short time they were able to diagnose the problem to my cam installation. Somehow I installed the 4,5,6 cam 180 degrees out. By noon Mike and Chris had the motor out of the car and were ready to fix the cam issue. While he was in there he check cam shaft parallelity, reset cam timing and adjusted the valves.

Motor went back in the car and we still were unable to get the clutch to release properly after adjusting it. The problem was the new pressure plate not disengaging till the pedal was ¼ inch from the floor. The car started right up and sounded good, just like six cylinders should. 
After all of that work, now onto the Dyno tune. While on the dyno the car’s exhaust was glowing orange, pretty cool. The not so cool part is; we ran into a boost control issue with the GSF headers. The tube feeding the wastegate is fed at a bad angle and is not able to flow enough into the wastegate at high RPM, allowing full boost control.
Chris and Tony are amazing tuners.
I have included a few pix and video to show the final numbers of the tune. I don’t have a print out of the power and torque curve yet, but will try to post something later.
Now the car is back in San Diego at KB Motor sports where they will be working to solve the clutch issue.
More to come…
